# TowerOps Production Deployment Guide
This guide covers deploying TowerOps to production with TimescaleDB, email notifications, and monitoring capabilities.
## Prerequisites
- PostgreSQL 14+ with TimescaleDB extension installed
- Elixir 1.19+ and Erlang 27+
- SSL certificate for HTTPS
- SMTP server for email notifications
## Environment Variables
Create a `.env.prod` file or configure these environment variables in your deployment platform:
### Required
```bash
# Secret key for encryption (generate with: mix phx.gen.secret)
SECRET_KEY_BASE=your-secret-key-here
# Database URL
DATABASE_URL=postgresql://user:password@host:port/towerops_prod
# Application URL
PHX_HOST=towerops.example.com
PORT=4000
# Environment
MIX_ENV=prod
```
### Email Configuration
```bash
# SMTP settings for alert notifications
SMTP_RELAY=smtp.example.com
SMTP_USERNAME=your-smtp-username
SMTP_PASSWORD=your-smtp-password
SMTP_PORT=587
SMTP_TLS=true
# From address for emails
ALERT_FROM_EMAIL=alerts@towerops.example.com
ALERT_FROM_NAME="TowerOps Alerts"
```
### Optional
```bash
# Custom check interval (default: 300 seconds / 5 minutes)
DEFAULT_CHECK_INTERVAL_SECONDS=300
# TimescaleDB retention (default: 90 days)
MONITORING_RETENTION_DAYS=90
# TimescaleDB compression (default: 7 days)
MONITORING_COMPRESSION_DAYS=7
```
## Database Setup
**Important**: TimescaleDB must be installed on your PostgreSQL server. See [TIMESCALEDB.md](TIMESCALEDB.md) for installation instructions.
### 1. Install TimescaleDB Extension
Connect to your PostgreSQL database and enable TimescaleDB:
```sql
CREATE EXTENSION IF NOT EXISTS timescaledb CASCADE;
```
### 2. Create Database
```bash
# Development
mix ecto.create
# Production
MIX_ENV=prod mix ecto.create
```
### 3. Run Migrations
```bash
# Development
mix ecto.migrate
# Production
MIX_ENV=prod mix ecto.migrate
```
This will:
- Create all necessary tables
- Convert `monitoring_checks` to TimescaleDB hypertable
- Set up retention policies (auto-delete data older than 90 days)
- Configure compression policies (compress data older than 7 days)
- Create continuous aggregates for dashboard performance
## Application Configuration
### Production Config
Update `config/runtime.exs` with your production settings. Key configurations:
#### Database Pool Size
```elixir
config :towerops, Towerops.Repo,
pool_size: String.to_integer(System.get_env("POOL_SIZE") || "10")
```
#### Mailer Configuration
The application uses Swoosh for email delivery. Update the mailer configuration:
```elixir
config :towerops, Towerops.Mailer,
adapter: Swoosh.Adapters.SMTP,
relay: System.get_env("SMTP_RELAY"),
username: System.get_env("SMTP_USERNAME"),
password: System.get_env("SMTP_PASSWORD"),
port: String.to_integer(System.get_env("SMTP_PORT") || "587"),
tls: :always
```
## Building for Production
### 1. Install Dependencies
```bash
mix deps.get --only prod
```
### 2. Compile Application
```bash
MIX_ENV=prod mix compile
```
### 3. Build Assets
```bash
MIX_ENV=prod mix assets.deploy
```
This will:
- Build and minify CSS with Tailwind v4
- Bundle JavaScript with esbuild
- Generate digested asset files
### 4. Create Release
```bash
MIX_ENV=prod mix release
```
The release will be created in `_build/prod/rel/towerops/`.
## Deployment
### Using Releases
```bash
# Start the release
_build/prod/rel/towerops/bin/towerops start
# Run as daemon
_build/prod/rel/towerops/bin/towerops daemon
# Check status
_build/prod/rel/towerops/bin/towerops pid
# Stop
_build/prod/rel/towerops/bin/towerops stop
```
### Using systemd
Create `/etc/systemd/system/towerops.service`:
```ini
[Unit]
Description=TowerOps Monitoring Service
After=network.target postgresql.service
[Service]
Type=forking
User=towerops
Group=towerops
WorkingDirectory=/opt/towerops
Environment="PORT=4000"
Environment="MIX_ENV=prod"
ExecStart=/opt/towerops/_build/prod/rel/towerops/bin/towerops daemon
ExecStop=/opt/towerops/_build/prod/rel/towerops/bin/towerops stop
Restart=on-failure
RestartSec=5
SyslogIdentifier=towerops
[Install]
WantedBy=multi-user.target
```
Enable and start:
```bash
sudo systemctl daemon-reload
sudo systemctl enable towerops
sudo systemctl start towerops
sudo systemctl status towerops
```
### Using Docker
Create `Dockerfile`:
```dockerfile
FROM elixir:1.19-alpine AS build
RUN apk add --no-cache build-base git nodejs npm
WORKDIR /app
# Install hex and rebar
RUN mix local.hex --force && \
mix local.rebar --force
ENV MIX_ENV=prod
# Install dependencies
COPY mix.exs mix.lock ./
RUN mix deps.get --only prod
# Copy application
COPY config config
COPY lib lib
COPY priv priv
COPY assets assets
# Build assets
RUN mix assets.deploy
# Compile and build release
RUN mix compile
RUN mix release
# Runtime stage
FROM alpine:3.18
RUN apk add --no-cache libstdc++ openssl ncurses-libs
WORKDIR /app
COPY --from=build /app/_build/prod/rel/towerops ./
ENV HOME=/app
ENV PORT=4000
ENV MIX_ENV=prod
CMD ["bin/towerops", "start"]
```
Build and run:
```bash
docker build -t towerops .
docker run -d \
--name towerops \
-p 4000:4000 \
--env-file .env.prod \
towerops
```
## Monitoring System
The monitoring system starts automatically when the application boots. It will:
1. **Start Equipment Monitors**: Create a GenServer worker for each equipment with `monitoring_enabled: true`
2. **Ping Equipment**: Each worker pings its equipment at the configured interval
3. **Record Checks**: Results are stored in `monitoring_checks` TimescaleDB hypertable
4. **Create Alerts**: Status changes trigger alert creation
5. **Send Emails**: Owners and admins receive email notifications for down/up events
6. **Broadcast Updates**: Real-time UI updates via Phoenix PubSub
### Monitoring Behavior by Environment
- **All Environments** (dev/test/prod):
- TimescaleDB features enabled (hypertables, retention, compression, aggregates)
- Monitoring system active
- **Production (`MIX_ENV=prod`)**:
- Email notifications sent to organization owners/admins
- **Development/Test**:
- Email notifications disabled (to avoid test database connection issues)
- Monitoring system runs but emails are suppressed
## SSL/TLS Configuration
### Using Nginx Reverse Proxy
```nginx
upstream towerops {
server 127.0.0.1:4000;
}
server {
listen 80;
server_name towerops.example.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl http2;
server_name towerops.example.com;
ssl_certificate /etc/letsencrypt/live/towerops.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/towerops.example.com/privkey.pem;
location / {
proxy_pass http://towerops;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
```
## Production Checklist
### Pre-Deployment
- [ ] Database created with TimescaleDB extension installed
- [ ] All environment variables configured
- [ ] SSL certificate obtained and configured
- [ ] SMTP server configured and tested
- [ ] Assets built and digested
- [ ] Release created successfully
### Post-Deployment
- [ ] Application starts without errors
- [ ] Database migrations ran successfully
- [ ] TimescaleDB hypertables created (`\d+ monitoring_checks` shows hypertable)
- [ ] Continuous aggregates created (`SELECT * FROM timescaledb_information.continuous_aggregates;`)
- [ ] Can access application via HTTPS
- [ ] User registration works
- [ ] Can create organization
- [ ] Can add sites and equipment
- [ ] Monitoring workers start for enabled equipment
- [ ] Ping checks are being recorded
- [ ] Alerts are created on status changes
- [ ] Email notifications are sent
- [ ] LiveView updates work in real-time
### Monitoring
- [ ] Check application logs for errors
- [ ] Monitor database connections
- [ ] Monitor memory usage (GenServer workers)
- [ ] Check email delivery logs
- [ ] Verify TimescaleDB compression is working
- [ ] Verify retention policies are cleaning old data
## Database Maintenance
### Verify TimescaleDB Status
```sql
-- Check hypertables
SELECT * FROM timescaledb_information.hypertables;
-- Check compression
SELECT * FROM timescaledb_information.chunks WHERE is_compressed = true;
-- Check continuous aggregates
SELECT * FROM timescaledb_information.continuous_aggregates;
-- Check retention policies
SELECT * FROM timescaledb_information.jobs WHERE proc_name = 'policy_retention';
```
### Manual Compression
```sql
-- Compress specific chunk
SELECT compress_chunk('_timescaledb_internal._hyper_1_1_chunk');
-- Compress all chunks older than 7 days
SELECT compress_chunk(chunk) FROM (
SELECT show_chunks('monitoring_checks', older_than => INTERVAL '7 days') AS chunk
) AS chunks;
```
### Backup and Restore
```bash
# Backup (includes TimescaleDB metadata)
pg_dump -Fc -d towerops_prod > towerops_backup.dump
# Restore
pg_restore -d towerops_prod towerops_backup.dump
```
## Scaling Considerations
### Database
- Monitor `monitoring_checks` table size and growth rate
- Adjust retention policy if needed (default: 90 days)
- Consider read replicas for heavy dashboard usage
- TimescaleDB compression reduces storage by 90%+
### Application
- Scale horizontally by running multiple instances
- Use load balancer with sticky sessions for LiveView
- Monitor GenServer worker memory usage
- Consider distributed Erlang if needed
### Email
- Use transactional email service (SendGrid, Postmark, etc.) for reliability
- Implement rate limiting if needed
- Monitor email delivery failures
## Troubleshooting
### Monitoring Not Working
Check logs for GenServer errors:
```bash
tail -f /var/log/towerops/error.log
```
Verify equipment has monitoring enabled:
```sql
SELECT id, name, monitoring_enabled, check_interval_seconds
FROM equipment;
```
### TimescaleDB Not Active
Verify extension is loaded:
```sql
\dx timescaledb
SELECT * FROM timescaledb_information.hypertables;
```
If missing:
1. Ensure TimescaleDB is installed (see TIMESCALEDB.md)
2. Drop and recreate the database: `mix ecto.drop && mix ecto.create && mix ecto.migrate`
### Email Not Sending
Test SMTP connection:
```elixir
# In iex -S mix
Swoosh.Email.new()
|> Swoosh.Email.to("test@example.com")
|> Swoosh.Email.from({"TowerOps", "alerts@towerops.example.com"})
|> Swoosh.Email.subject("Test")
|> Swoosh.Email.text_body("Test email")
|> Towerops.Mailer.deliver()
```
Check environment variables are set correctly.

# LibreNMS Integration
This document explains how to import MIB files and device profiles from a LibreNMS installation into Towerops.
## Quick Start
Import device profiles from LibreNMS (no authentication needed):
```bash
mix upload_librenms --librenms-path ~/dev/librenms
```
Upload everything including MIBs (requires superuser API token):
```bash
mix upload_librenms --librenms-path ~/dev/librenms --token your-api-token
```
This will:
1. Upload all MIB files from `~/dev/librenms/mibs/` to the server (if --token provided)
2. Import all device profiles from `~/dev/librenms/resources/definitions/`
## Options
### Basic Usage
```bash
# Upload to local server (default: http://localhost:4000)
mix upload_librenms --librenms-path ~/dev/librenms
# Upload to production server
mix upload_librenms --librenms-path ~/dev/librenms \
--url https://towerops.net \
--token your-api-token-here
# Upload specific profiles only
mix upload_librenms --librenms-path ~/dev/librenms \
--profiles routeros,ios,iosxe
```
### Command-Line Options
- `--librenms-path` - Path to LibreNMS installation (required)
- `--url` - Server URL (default: http://localhost:4000)
- `--token` - API token for authentication (required for remote servers)
- `--profiles` - Comma-separated list of profiles to import (default: all)
## What Gets Uploaded
### MIB Files
All MIB files from `{librenms-path}/mibs/` are uploaded, organized by vendor:
```
~/dev/librenms/mibs/
├── mikrotik/
│ ├── MIKROTIK-MIB
│ └── ...
├── cisco/
│ ├── CISCO-SMI
│ └── ...
└── ...
```
Each vendor's MIBs are uploaded separately with the vendor name preserved.
### Device Profiles
Device profiles are imported from LibreNMS YAML definitions:
```
~/dev/librenms/resources/definitions/
├── os_detection/
│ ├── routeros.yaml # Detection patterns
│ └── ios.yaml
└── os_discovery/
├── routeros.yaml # Device info & sensors
└── ios.yaml
```
For each profile, the following is imported:
- **Detection patterns** (sysObjectID, sysDescr regex)
- **Device info OIDs** (serial number, firmware version, hardware)
- **Sensor OIDs** (temperature, voltage, current, power, fanspeed)
**Note**: Only scalar sensors (ending with `.0`) are imported. Table-based sensors with `{{ $index }}` templates are skipped.
## Authentication
### Profile Import Only (No Token Needed)
Profile imports work without authentication since they only write to the local database:
```bash
# Import profiles without uploading MIBs
mix upload_librenms --librenms-path ~/dev/librenms
```
### MIB Upload (Token Required)
MIB uploads require a **superuser API token** for both local and remote servers:
```bash
# Upload MIBs + import profiles (local server)
mix upload_librenms --librenms-path ~/dev/librenms \
--token your-superuser-token
# Upload to remote server
mix upload_librenms --librenms-path ~/dev/librenms \
--url https://towerops.net \
--token your-superuser-token
```
**Creating an API Token:**
1. Log in to Towerops as a superuser
2. Navigate to Settings → API Tokens
3. Create a new token
4. Copy the token value
**Note**: The token MUST be from a superuser account. Regular user tokens will be rejected with a 403 Forbidden error.
## Examples
### Example 1: Import Profiles Only (Quick Start)
Import device profiles without uploading MIBs (no token needed):
```bash
mix upload_librenms --librenms-path ~/dev/librenms
```
Output:
```
Skipping MIB upload: --token is required for MIB uploads (superuser API token needed)
Step 2/2: Importing device profiles from ~/dev/librenms/resources/definitions...
Importing 150 specified profiles
Importing profile: routeros
✓ routeros: created/updated successfully
...
Import complete: 150 succeeded, 0 failed
Upload complete!
```
### Example 2: Upload Everything (MIBs + Profiles)
Upload MIBs and import profiles (requires superuser token):
```bash
mix upload_librenms --librenms-path ~/dev/librenms --token sk_dev_abc123...
```
Output:
```
Step 1/2: Uploading MIB files from ~/dev/librenms/mibs...
Found 500 vendor directories
Uploading MIBs for vendor: mikrotik
Uploading: MIKROTIK-MIB
Uploading: ...
MIB upload complete: 5000 succeeded, 0 failed
Step 2/2: Importing device profiles from ~/dev/librenms/resources/definitions...
Importing 150 specified profiles
Importing profile: routeros
✓ routeros: created/updated successfully
...
Import complete: 150 succeeded, 0 failed
Upload complete!
```
### Example 3: Update Specific Profiles
Re-import just the MikroTik and Cisco profiles (no MIB upload):
```bash
mix upload_librenms --librenms-path ~/dev/librenms \
--profiles routeros,ios,iosxe,nxos
```
### Example 4: Production Deployment
Upload everything to production server:
```bash
mix upload_librenms --librenms-path ~/dev/librenms \
--url https://towerops.net \
--token sk_live_abc123...
```
## Manual Tasks
You can also run each step separately if needed:
### Upload MIBs Only
```bash
mix upload_mibs --source-dir ~/dev/librenms/mibs \
--url https://towerops.net \
--token your-token
```
### Import Profiles Only
```bash
mix import_profiles --source-path ~/dev/librenms/resources/definitions \
--profiles routeros,ios
```
## Troubleshooting
### Error: "LibreNMS directory not found"
Make sure the path to your LibreNMS installation is correct:
```bash
ls -la ~/dev/librenms
# Should show mibs/ and resources/ directories
```
### Error: "No vendor directories found"
The mibs directory structure should have vendor subdirectories:
```bash
ls -la ~/dev/librenms/mibs/
# Should show directories like mikrotik/, cisco/, etc.
```
### Error: "Superuser access required"
MIB uploads require a superuser API token. Make sure you're using a token created by a superuser account.
### Warning: "Definitions directory not found"
LibreNMS moved the definitions from `includes/definitions/` to `resources/definitions/` in recent versions. Update your path accordingly.
## What's Imported
### RouterOS (MikroTik) Example
For the `routeros` profile, the following is imported:
**Profile Metadata:**
- Name: routeros
- Vendor: Mikrotik RouterOS
- Detection OID: .1.3.6.1.4.1.14988.1
- Priority: 100
**Device OIDs:**
- Serial number: `MIKROTIK-MIB::mtxrSerialNumber.0`
- Firmware version: `MIKROTIK-MIB::mtxrLicVersion.0`
**Sensor OIDs:**
- None (routeros only has table-based sensors which are skipped)
### Cisco IOS Example
For the `ios` profile:
**Profile Metadata:**
- Name: ios
- Vendor: Cisco IOS
- Detection Pattern: "Cisco Internetwork Operating System Software"
- Detection OID: .1.3.6.1.4.1.9.1.2330
- Priority: 100
**Device OIDs:**
- None (IOS doesn't define them in os_discovery)
**Sensor OIDs:**
- None (IOS only has table-based sensors which are skipped)
## Database Schema
The imported profiles are stored in the database:
- `device_profiles` - Profile metadata (name, vendor, detection patterns)
- `profile_device_oids` - Device identification OIDs (serial, firmware, etc.)
- `profile_sensor_oids` - Sensor discovery OIDs (temperature, voltage, etc.)
You can query them:
```elixir
# Get all profiles
Towerops.Profiles.list_profiles()
# Get specific profile with associations
Towerops.Profiles.get_profile("routeros")
# Match a device to a profile
system_info = %{
sys_descr: "RouterOS 7.16.1",
sys_object_id: ".1.3.6.1.4.1.14988.1"
}
Towerops.Profiles.match_profile(system_info)
```
## Next Steps
After importing profiles:
1. **Test device discovery** - Discover a MikroTik or Cisco device to verify profile matching works
2. **Check MIB translation** - Verify that MIB names are being translated to numeric OIDs correctly
3. **Add more profiles** - Import additional vendor profiles as needed
4. **Build Web UI** - Create LiveView pages for managing profiles in the browser

# MIB Resolution with net-snmp C Library
## Implementation Summary
Successfully integrated the net-snmp C library for ultra-fast MIB name resolution, achieving LibreNMS-style performance.
## Performance Comparison
| Method | First Resolution | Cached Resolution |
|--------|------------------|-------------------|
| **Subprocess (old)** | ~300-400ms | <1µs (ETS cache) |
| **net-snmp C library (new)** | ~1-20µs | ~1-20µs (in-memory) |
## Benchmark Results
```
sysDescr avg: 1.6µs min: 1µs max: 6µs
IF-MIB::ifDescr avg: 17.4µs min: 9µs max: 23µs
SNMPv2-MIB::sysUpTime avg: 12.3µs min: 7µs max: 19µs
IF-MIB::ifInOctets avg: 3.5µs min: 2µs max: 6µs
IP-MIB::ipAdEntAddr avg: 4.8µs min: 1µs max: 14µs
```
**Result**: 17-300x faster than subprocess approach!
## Architecture
### Stack
```
Elixir (MibCache GenServer)
↓
Rustler NIF (towerops_native)
↓
Rust FFI bindings (netsnmp_ffi.rs)
↓
net-snmp C library (libnetsnmp)
```
### Key Components
1. **netsnmp_ffi.rs** - Rust FFI bindings to net-snmp C functions
- `initialize_snmp_library()` - One-time MIB loading (~1-2s startup)
- `resolve_mib_name()` - Fast OID resolution (<20µs)
2. **mib.rs** - Rust NIF implementation
- `load_mib_directory_impl()` - Configure MIB search paths
- `init_mib_library_impl()` - Initialize net-snmp (DirtyCpu scheduler)
- `resolve_oid_impl()` - Resolve MIB names with Rust HashMap cache
3. **lib.rs** - Rustler NIF exports
- Exports functions to Elixir as `ToweropsNative` module
4. **lib/towerops_native.ex** - Elixir NIF wrapper
- `load_mib_directory/1` - Set MIB search paths
- `init_mib_library/0` - Initialize net-snmp library
- `resolve_oid/1` - Resolve MIB name to numeric OID
5. **lib/towerops/profiles/mib_cache.ex** - GenServer cache layer
- Async pre-resolution of common MIBs at startup
- ETS cache for ultra-fast lookups
- Runtime fallback for cache misses
### Initialization Flow
1. Application starts → `load_mib_directory/1` called with MIB paths
2. First `resolve_oid/1` call triggers lazy initialization:
- Sets `MIBDIRS` and `MIBS=ALL` environment variables
- Calls `init_snmp()` and `netsnmp_init_mib()`
- Calls `read_all_mibs()` to load all MIBs into memory (~1-2s)
3. Subsequent calls use in-memory MIB tree (fast!)
### Resolution Flow
1. Elixir calls `ToweropsNative.resolve_oid("sysDescr")`
2. Rust checks Rust HashMap cache (miss on first call)
3. Calls C `read_objid()` to resolve MIB name → OID array
4. Calls C `snprint_objid()` to format OID as string
5. Caches result in Rust HashMap
6. Returns to Elixir
7. MibCache GenServer caches in ETS
## Files Created/Modified
### New Files
- `native/towerops_native/src/netsnmp_ffi.rs` - C library FFI bindings
- `native/towerops_native/build.rs` - Cargo build script for linking
### Modified Files
- `native/towerops_native/Cargo.toml` - Added `libc` and `cc` dependencies
- `native/towerops_native/src/lib.rs` - NIF function exports
- `native/towerops_native/src/mib.rs` - Refactored for C library integration
- `lib/towerops_native.ex` - Added `init_mib_library/0` function
### Existing Files (unchanged)
- `lib/towerops/profiles/mib_cache.ex` - Still provides caching layer
- `lib/towerops/profiles/yaml_profiles.ex` - Uses MibCache as before
- `lib/towerops/snmp/client.ex` - Uses MibCache as before
## Build Requirements
### Development (macOS)
- Homebrew net-snmp: `brew install net-snmp`
- Headers: `/usr/include/net-snmp/*` or `/opt/homebrew/include/net-snmp/*`
- Library: `/usr/lib/libnetsnmp.dylib` or `/opt/homebrew/lib/libnetsnmp.dylib`
### Production (Docker/Linux)
- Package: `net-snmp` and `net-snmp-devel` (CentOS) or `libsnmp-dev` (Debian/Ubuntu)
- Headers: `/usr/include/net-snmp/*`
- Library: `/usr/lib/x86_64-linux-gnu/libnetsnmp.so`
### Build Process
1. `build.rs` uses `net-snmp-config --libs` to get library paths
2. Links against `libnetsnmp` dynamically
3. Works in both dev (macOS) and prod (Linux Docker)
## Advantages
1. **Performance**: 17-300x faster than subprocess calls
2. **LibreNMS-aligned**: Same C library as LibreNMS PHP extension
3. **Memory-efficient**: MIBs loaded once, shared across all resolutions
4. **Thread-safe**: C library handles concurrent access
5. **Works in Docker**: Dynamic linking finds system libnetsnmp
6. **No MIB pre-compilation**: MIBs loaded as text files (easy updates)
## Trade-offs
1. **Startup time**: ~1-2 seconds to load all MIBs (one-time cost)
- Happens lazily on first resolution call
- Runs on DirtyCpu scheduler (doesn't block main BEAM schedulers)
2. **C dependency**: Requires net-snmp library installed
- Already required for `snmptranslate` command
- Standard package on all Linux distros
3. **Complexity**: Added Rust FFI layer
- Well-documented and type-safe
- Similar to PHP's SNMP extension internals
## Testing
All existing tests pass:
```bash
mix test test/towerops/profiles/yaml_profiles_test.exs # 12 tests, 0 failures
mix test test/towerops/snmp/discovery_test.exs # 13 tests, 0 failures
```
## Future Enhancements
1. **Lazy MIB loading**: Only load MIBs for matched vendors (faster startup)
2. **MIB dependency tracking**: Load only required MIB dependencies
3. **Shared library caching**: Share MIB tree across multiple NIF instances
4. **Telemetry**: Track resolution times and cache hit rates

The Towerops Mobile API uses bearer token authentication. All authenticated requests must include an `Authorization` header:
```
Authorization: Bearer <session_token>
```
### QR Code Login Flow
The recommended authentication method is QR code login, which allows users to authenticate without entering credentials in the mobile app.
#### Step 1: User Generates QR Code
User logs into the web interface at `/mobile/qr-login` and generates a QR code containing a temporary token.
#### Step 2: Verify QR Token
**Endpoint:** `POST /api/v1/mobile/auth/qr/verify`
Verifies that a scanned QR token is valid before proceeding with login.
**Request Body:**
```json
{
"token": "base64-encoded-token-from-qr-code"
}

## Error Handling
All API endpoints follow consistent error response formats.
### HTTP Status Codes
- `200 OK`: Request succeeded
- `400 Bad Request`: Invalid request parameters
- `401 Unauthorized`: Missing or invalid authentication token
- `403 Forbidden`: Authenticated but not authorized for this resource
- `404 Not Found`: Resource not found
- `422 Unprocessable Entity`: Validation errors
- `500 Internal Server Error`: Server error
### Error Response Format
```json
{
"error": "Human-readable error message"
}
```
For validation errors (422):
```json
{
"error": "Failed to create session",
"details": {
"field_name": ["error message"]
}
}
```
## Rate Limiting
The API does not currently implement rate limiting, but it may be added in future versions. Implement exponential backoff in your client for failed requests.
## Best Practices
### Token Storage
- Store session tokens securely in the device keychain (iOS) or keystore (Android)
- Never log or expose tokens in plaintext
- Clear tokens on logout
### Session Management
- Check session expiration before making requests
- Implement automatic token refresh or re-authentication when sessions expire
- Handle 401 responses by prompting for re-authentication
### Network Requests
- Implement timeout handling (30 seconds recommended)
- Use exponential backoff for retries
- Cache responses appropriately (organizations list, equipment details)
- Update last_used_at is automatic - no need to ping
### Error Handling
- Display user-friendly error messages
- Log errors for debugging
- Handle network connectivity issues gracefully
- Implement offline mode where appropriate
## Example Client Implementation
### Swift (iOS)
```swift
import Foundation
class ToweropsAPI {
private let baseURL = "https://your-instance.com/api/v1/mobile"
private var sessionToken: String?
// Authenticate with QR token
func completeQRLogin(token: String, deviceInfo: DeviceInfo) async throws -> SessionToken {
let url = URL(string: "\(baseURL)/auth/qr/complete")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
let body = [
"token": token,
"device_name": deviceInfo.name,
"device_os": deviceInfo.os,
"app_version": deviceInfo.appVersion
]
request.httpBody = try JSONEncoder().encode(body)
let (data, response) = try await URLSession.shared.data(for: request)
guard let httpResponse = response as? HTTPURLResponse,
httpResponse.statusCode == 200 else {
throw APIError.authenticationFailed
}
let result = try JSONDecoder().decode(SessionToken.self, from: data)
self.sessionToken = result.session_token
return result
}
// Fetch organizations
func fetchOrganizations() async throws -> [Organization] {
guard let token = sessionToken else {
throw APIError.notAuthenticated
}
let url = URL(string: "\(baseURL)/organizations")!
var request = URLRequest(url: url)
request.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
let (data, response) = try await URLSession.shared.data(for: request)
guard let httpResponse = response as? HTTPURLResponse,
httpResponse.statusCode == 200 else {
throw APIError.requestFailed
}
let result = try JSONDecoder().decode(OrganizationsResponse.self, from: data)
return result.organizations
}
}
```
### Kotlin (Android)
```kotlin
import okhttp3.*
import kotlinx.serialization.json.Json
class ToweropsAPI(private val baseURL: String = "https://your-instance.com/api/v1/mobile") {
private val client = OkHttpClient()
private var sessionToken: String? = null
// Authenticate with QR token
suspend fun completeQRLogin(token: String, deviceInfo: DeviceInfo): SessionToken {
val json = """
{
"token": "$token",
"device_name": "${deviceInfo.name}",
"device_os": "${deviceInfo.os}",
"app_version": "${deviceInfo.appVersion}"
}
""".trimIndent()
val request = Request.Builder()
.url("$baseURL/auth/qr/complete")
.post(RequestBody.create(MediaType.parse("application/json"), json))
.build()
val response = client.newCall(request).execute()
if (!response.isSuccessful) {
throw APIException("Authentication failed")
}
val result = Json.decodeFromString<SessionToken>(response.body()!!.string())
sessionToken = result.session_token
return result
}
// Fetch organizations
suspend fun fetchOrganizations(): List<Organization> {
val token = sessionToken ?: throw APIException("Not authenticated")
val request = Request.Builder()

# Device Profile Management
This document describes how to manage SNMP device profiles in Towerops. Device profiles define how to discover and monitor different types of network equipment via SNMP.
## Overview
Towerops uses a database-driven profile system that supports 671+ device types dynamically without code changes. Profiles are imported from external YAML definitions and stored in the database.
## Architecture
**Profile Discovery Flow:**
1. Device performs SNMP discovery
2. System reads sysDescr and sysObjectID from device
3. Matches against detection rules in database
4. Uses matched profile to discover sensors, CPU, memory, etc.
5. Saves discovered data for monitoring and graphing
**Profile Components:**
- **Detection Rules**: sysObjectID prefix matching, sysDescr regex patterns
- **Sensor Definitions**: Temperature, voltage, current, power, fan speed, state sensors
- **Processor Definitions**: CPU usage monitoring (converted to percent sensors)
- **Memory Pool Definitions**: Memory usage monitoring
- **OS Definitions**: Firmware version, serial number, location data
## Exporting Profiles Locally
Use the `mix export_profiles` task to export profiles from an external source to JSON format:
```bash
# Export all profiles
mix export_profiles --librenms-path ~/dev/librenms --output profiles.json
# Export specific profiles only
mix export_profiles --librenms-path ~/dev/librenms --profiles epmp,unifi,airos-af --output profiles.json
```
**Options:**
- `--librenms-path PATH` - Path to external source installation (required)
- `--output PATH` - Output JSON file path (default: profiles.json)
- `--profiles LIST` - Comma-separated list of specific profiles to export (optional)
**Output:**
The task generates a JSON file containing all profile data (detection rules, sensor definitions, etc.) suitable for uploading to production.
## Importing Profiles to Production
**Requirements:**
- Superuser account (user with `is_superuser = true`)
- API token created by superuser account
### Step 1: Create Superuser API Token
1. Log in to Towerops as a superuser
2. Navigate to your organization settings
3. Create a new API token
4. Copy the token (shown only once) - it will start with `towerops_`
**Note**: Only API tokens created by superuser accounts can import device profiles.
### Step 2: Upload Profiles
```bash
curl -X POST https://towerops.net/api/v1/profiles/import \
-H "Authorization: Bearer YOUR_SUPERUSER_API_TOKEN" \
-H "Content-Type: application/json" \
-d @profiles.json
```
**Response:**
```json
{
"status": "queued",
"job_id": "uuid",
"profile_count": 15,
"message": "Import job queued successfully. 15 profiles will be imported in the background."
}
```
### Step 3: Monitor Import Progress
The import runs as a background job in the `maintenance` queue. Monitor progress via:
1. **Server logs:**
```bash
kubectl logs -n towerops deployment/towerops | grep "profile import"
```
2. **Exq dashboard:**
Navigate to `/dashboard` and check the Maintenance queue
**Log messages:**
- `Starting profile import job <job_id> with N profiles` - Job started
- `[<job_id>] Successfully imported profile: <os>` - Profile imported
- `[<job_id>] Failed to import profile <os>: <reason>` - Import error
- `[<job_id>] Import complete: N succeeded, M failed` - Job finished
## Profile Structure
### Detection YAML (os_detection/*)
```yaml
os: epmp
text: Cambium epmp
type: wireless
group: cambium
icon: cambium
discovery:
- sysObjectID:
- ".1.3.6.1.4.1.17713.21"
```
### Discovery YAML (os_discovery/*)
```yaml
mib: CAMBIUM-PMP80211-MIB
modules:
os:
version: CAMBIUM-PMP80211-MIB::cambiumCurrentuImageVersion.0
serial: CAMBIUM-PMP80211-MIB::cambiumEPMPMSN.0
processors:
data:
- oid: sysCPUUsage
num_oid: ".1.3.6.1.4.1.17713.21.2.1.64.{{ $index }}"
type: cambium-cpu
precision: 10
sensors:
temperature:
data:
- oid: boardTemp
num_oid: ".1.3.6.1.4.1.17713.21.1.2.1.0"
descr: Board Temperature
precision: 10
```
## Database Schema
**device_profiles** - Main profile table
- `os` - Operating system identifier (e.g., "epmp", "unifi")
- `text` - Display name (e.g., "Cambium epmp")
- `type` - Device type (wireless, switch, router, etc.)
- `group` - Manufacturer group (cambium, ubiquiti, cisco, etc.)
- `priority` - Matching priority (lower = higher priority)
- `enabled` - Whether profile is active
**profile_detection_rules** - Device detection patterns
- `rule_type` - "sysObjectID", "sysDescr", "sysDescr_regex"
- `pattern` - OID prefix or regex pattern
- `value` - Exact match value
**profile_sensor_definitions** - Sensor discovery definitions
- `sensor_class` - temperature, voltage, current, power, fanspeed, humidity, dbm, snr, percent, count, frequency, state
- `oid` - Symbolic OID name
- `num_oid` - Numeric OID (e.g., ".1.3.6.1.4.1.17713.21.2.1.36.{{ $index }}")
- `descr` - Sensor description
- `divisor` - Value divisor for unit conversion
- `precision` - Number of decimal places (stored in divisor field)
**profile_processor_definitions** - CPU discovery definitions
- `oid` - Symbolic OID name
- `num_oid` - Numeric OID
- `precision` - Divisor for CPU percentage (e.g., 10 means divide by 10)
- `type` - Processor type identifier
## Force Replacement
All profile imports use force replacement - existing profiles with the same `os` name are deleted before importing. This ensures clean updates without conflicts.
## Troubleshooting
**Import fails immediately:**
- Check you're logged in as a superuser (`is_superuser = true`)
- Verify session cookie is correct and not expired
- Check JSON format is valid: `jq . profiles.json`
**Profiles import but discovery doesn't work:**
- Check profile detection rules match device sysObjectID/sysDescr
- Verify sensor OIDs are numeric (not symbolic MIB names)
- Check logs for SNMP walk errors
- Test SNMP manually: `snmpwalk -v2c -c public <ip> <oid>`
**Sensor indices conflict:**
- Sensor indices must be unique per device
- Scalar sensors (index .0) use descriptive names (e.g., "dfs_detected_count")
- Table sensors use class prefix (e.g., "temperature_1", "voltage_2")
**CPU not showing:**
- Processor definitions are converted to "percent" type sensors
- Check divisor/precision is correct (usually 10 or 100)
- Verify num_oid is accessible via SNMP
## Examples
### Export ePMP and UniFi profiles
```bash
mix export_profiles \
--librenms-path ~/dev/librenms \
--profiles epmp,unifi \
--output production_profiles.json
```
### Import to production
```bash
# Use your superuser API token
SUPERUSER_TOKEN="towerops_abc123..."
curl -X POST https://towerops.net/api/v1/profiles/import \
-H "Authorization: Bearer ${SUPERUSER_TOKEN}" \
-H "Content-Type: application/json" \
-d @production_profiles.json
```
### Check import status
```bash
kubectl logs -n towerops deployment/towerops --tail=100 | grep "Import complete"
```

## Security
- Profile import requires superuser API token
- Only tokens created by superusers can import profiles
- User who created the token must still be a superuser
- Runs in background to prevent timeouts
- Validates profile data before importing
- Logs all import operations with user email
## Supported Profile Count
As of January 2026, the system supports **671+ device profiles** including:
- Cambium ePMP, PMP, cnPilot
- Ubiquiti AirFiber, airMAX, UniFi
- Cisco IOS, IOS-XE, NX-OS
- MikroTik RouterOS
- Juniper JunOS
- And many more...
New profiles can be added without code changes by exporting and importing.
