The compute pipeline now actually runs: per-pixel path loss over LIDAR
terrain, antenna pattern lookup, real GeoTIFF + colored PNG output,
Leaflet imageOverlay rendering with opacity slider and dBm legend.
Propagation:
- Towerops.Coverages.Propagation: Friis FSPL + Bullington single-knife-edge
diffraction (ITU-R P.526). Pure Elixir, closed-form, no NIF dependency.
Clean signature so a future ITM/Longley-Rice backend can drop in.
- Towerops.Coverages.Profile: AAIGrid sampler with elevation_at, sample
along great circle, haversine distance.
- Towerops.Coverages.Raster: Float32 GeoTIFF via gdal_translate (with VRT
wrapper) and colored PNG via gdaldem color-relief. Outputs to
priv/static/coverage/<org>/<id>/, served by existing Plug.Static.
Worker:
- Towerops.Workers.CoverageWorker now does the full pipeline: bbox compute
-> Towerops.Lidar.get_elevation_grid -> per-pixel Task.async_stream
(parallel = schedulers) running antenna pattern lookup + propagation +
RSSI threshold check, write rasters. Configurable terrain source via
:coverage_terrain_module application env so tests can stub. Friendly
failure messages for :no_tile, :grid_too_large, :nodata,
:unknown_antenna, :missing_location.
Bundled antenna catalog (~95 entries):
- AntennaCatalog with compact specs for every antenna in the request list:
Cambium, ALPHA, Antel, ITELITE, KP Performance, L-com, MARS, MikroTik,
Mimosa, MTI, RADWIN, RF Elements, Ruckus, Tarana, Simulate, Ubiquiti.
- Antenna.from_spec/1 synthesizes 360+360 attenuation patterns from
gain+beamwidth (cosine-squared main lobe, smooth transition,
front-to-back floor with mild ripple). Real .ant files in priv/antennas/
override the catalog by slug. Test fixtures moved to test/support.
Schema (migration add_radio_fields_to_coverages):
- tx_power_dbm replaces eirp_dbm; EIRP is now derived as
tx_power + antenna.gain - cable_loss in Coverage.eirp_dbm/2 and shown
live in the form header.
- cable_loss_db, sm_gain_dbi, latitude_override, longitude_override,
height_above_rooftop_m, tx_clearance_m, foliage_tuning (0-100 slider).
- Coverage.location/1 returns {lat, lon} from override or parent site.
UI:
- form.html.heex: cnHeat-style grouped form (Identity / Location /
Mounting / RF / Coverage extent), foliage tuning range slider,
computed EIRP badge in the header.
- show.html.heex: Leaflet map area with L.imageOverlay heatmap,
opacity slider, dBm color legend, antenna marker with directional
wedge for azimuth.
- assets/js/app.ts: CoverageMap hook registered.
Tests: 24 new (propagation reference values, profile sampling,
worker end-to-end with stubbed terrain that writes real GeoTIFF + PNG,
org-mismatch job-cancel guard). Full suite: 10815 tests.

TowerOps
Network monitoring and alerting platform built with Phoenix LiveView.
Features
- Multi-tenant architecture - Organizations with role-based permissions
- Site hierarchy - Organize equipment across multiple sites
- Automated monitoring - Real-time ping monitoring with configurable intervals
- Time-series data - Efficient storage with TimescaleDB (optional)
- Real-time updates - LiveView dashboard with PubSub
- Equipment tracking - Monitor network devices by IP address
Quick Start
Prerequisites
- Elixir 1.14+
- PostgreSQL 14+
- (Optional) TimescaleDB for production-grade time-series performance
Setup
# Install dependencies
mix setup
# Start the server
mix phx.server
Visit localhost:4000 from your browser.
TimescaleDB (Production Only)
Development: Uses standard PostgreSQL (no TimescaleDB required).
Production: TimescaleDB is automatically enabled for optimal performance with time-series data.
# Production deployment - install TimescaleDB first
brew tap timescale/tap && brew install timescaledb # macOS
# Then run migrations with MIX_ENV=prod
MIX_ENV=prod mix ecto.migrate
See TIMESCALEDB.md for detailed installation and configuration.
How it works: Migrations detect the environment (MIX_ENV) and only enable TimescaleDB features (hypertables, compression, retention policies, continuous aggregates) in production.
Encryption Setup (Production)
TowerOps uses AES-256-GCM encryption for sensitive data (SNMP communities, MikroTik API passwords, etc.).
Development/Test
Encryption keys are pre-configured in config/dev.exs and config/test.exs. No action required.
Production
Set the CLOAK_KEY environment variable with a base64-encoded 32-byte key:
# Generate encryption key
openssl rand -base64 32
Important:
- Store the generated key securely in 1Password or your secrets manager
- Never commit the production key to version control
- Losing the encryption key makes encrypted data unrecoverable
Kubernetes Deployment
If secret doesn't exist yet (new deployment):
# Generate CLOAK_KEY (store in 1Password first!)
CLOAK_KEY=$(openssl rand -base64 32)
# Create towerops-secrets with all required keys
kubectl create secret generic towerops-secrets \
--from-literal=RELEASE_COOKIE=$(openssl rand -base64 32) \
--from-literal=SECRET_KEY_BASE=$(mix phx.gen.secret) \
--from-literal=CLOAK_KEY="$CLOAK_KEY" \
-n towerops
If secret already exists (add CLOAK_KEY to existing secret):
# Store new key in 1Password first!
# Bash/Zsh:
CLOAK_KEY=$(openssl rand -base64 32)
# Fish shell:
set CLOAK_KEY (openssl rand -base64 32)
# Method 1: Using kubectl create with dry-run and apply
kubectl create secret generic towerops-secrets \
--from-literal=CLOAK_KEY="$CLOAK_KEY" \
--dry-run=client -o yaml | \
kubectl apply -f - -n towerops
# Method 2: Direct inline generation (works in all shells)
kubectl create secret generic towerops-secrets \
--from-literal=CLOAK_KEY="$(openssl rand -base64 32)" \
--dry-run=client -o yaml | \
kubectl apply -f - -n towerops
# Restart pods to pick up new key
kubectl rollout restart deployment/towerops -n towerops
Development
Database
mix ecto.create # Create database
mix ecto.migrate # Run migrations
mix ecto.reset # Drop, create, and migrate
Testing
mix test # Run all tests
mix test --trace # Run with detailed output
Code Quality
mix format # Format code with Styler
mix compile --warnings-as-errors
Firmware Version Tracking
The system automatically checks for latest firmware versions daily (2 AM dev, 4 AM prod). To manually trigger a firmware check:
# Start IEx console
iex -S mix phx.server
# Manually trigger firmware version fetch
Oban.insert(Towerops.Workers.FirmwareVersionFetcherWorker.new(%{}))
The worker will:
- Fetch the latest MikroTik RouterOS version from RSS feed
- Store version information in the database
- Enable firmware update indicators on device detail pages
Check the logs for fetch results:
# View recent Oban jobs
Towerops.Repo.all(Oban.Job) |> Enum.take(5)
