-# 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;
-    }
-}
-```
-

-- [ ] 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.
-
-## Support

-# 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

-
-## 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

-## Authentication
-
-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"
-}
-```
-
-**Response (200 OK):**
-```json
-{
-  "valid": true,
-  "user_email": "user@example.com"
-}
-```
-
-**Response (401 Unauthorized):**
-```json
-{
-  "valid": false,
-  "error": "Invalid or expired token"
-}
-```
-
-#### Step 3: Complete QR Login
-
-**Endpoint:** `POST /api/v1/mobile/auth/qr/complete`
-
-Completes the QR login by creating a long-lived mobile session (90 days).
-
-**Request Body:**
-```json
-{
-  "token": "base64-encoded-token-from-qr-code",
-  "device_name": "iPhone 15 Pro",
-  "device_os": "iOS 17.2",
-  "app_version": "1.0.0"
-}
-```
-
-**Response (200 OK):**
-```json
-{
-  "session_token": "long-lived-bearer-token",
-  "expires_at": "2026-04-15T19:44:25Z",
-  "user": {
-    "id": "user-uuid",
-    "email": "user@example.com"
-  }
-}
-```
-
-**Response (401 Unauthorized):**
-```json
-{
-  "error": "Invalid or expired token"
-}
-```
-
-**Response (422 Unprocessable Entity):**
-```json
-{
-  "error": "Failed to create session",
-  "details": {
-    "device_name": ["can't be blank"]
-  }
-}
-```
-
-**Notes:**
-- QR tokens expire after 5 minutes
-- QR tokens can only be used once
-- Session tokens expire after 90 days
-- Store the `session_token` securely in the device keychain/keystore

-
-## 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"

-
-    // 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")

-        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,

-# 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

-type: wireless
-group: cambium
-icon: cambium
-discovery:
-  - sysObjectID:
-      - ".1.3.6.1.4.1.17713.21"
-```
-
-### Discovery YAML (os_discovery/*)

-    data:
-      - oid: sysCPUUsage
-        num_oid: ".1.3.6.1.4.1.17713.21.2.1.64.{{ $index }}"

-## 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.
