Implemented all critical and nice-to-have Arista sensor improvements identified
in LibreNMS parity audit. Upgrades Arista EOS support from 85% to 100% parity.
Files Changed:
- lib/towerops/snmp/profiles/vendors/arista.ex (enhanced)
Added 4 major enhancements:
1. DOM power conversion (watts→dBm): Detects optical power sensors via regex,
converts using formula dBm = 10*log10(watts*1000), preserves original value
in metadata
2. Arista threshold discovery: Walks ARISTA-ENTITY-SENSOR-MIB threshold table
(OID 1.3.6.1.4.1.30065.3.3.1.1.1), applies 4 threshold types (low_critical,
low_warn, high_warn, high_critical), converts thresholds to dBm for optical
sensors
3. Smart grouping: Organizes sensors by SFPs, PSUs, Platform (chipsets), Power
Connectors, System for better UX
4. Description cleanup: Removes redundant "sensor" text, simplifies PSU naming,
cleans whitespace
- lib/towerops/snmp/profiles/dynamic.ex (integration)
Added apply_vendor_post_processing/3 to call Arista enhancements after sensor
discovery. Applies to both arista_eos and arista-mos profiles.
- test/towerops/snmp/profiles/vendors/arista_test.exs (comprehensive tests)
Added 23 new tests covering:
- DOM conversion (6 tests): Rx/Tx power, Xcvr power, non-DOM sensors, edge cases
- Threshold discovery (4 tests): Basic thresholds, dBm conversion, no thresholds,
SNMP failures
- Smart grouping (6 tests): SFPs, Xcvr, PSUs, power connectors, platform, system
- Description cleanup (5 tests): Trailing sensor, duplicate Sensor strings, PSU
naming, hotspot, whitespace
- End-to-end post-processing (1 test): All enhancements in correct order
All tests passing (30/30 in arista_test.exs, 6367/6367 total).
Result: Arista EOS support upgraded from 85% to 100% LibreNMS parity. All critical
gaps closed: optical power now displayed correctly in dBm, alerting enabled via
thresholds, sensors organized for better UX, descriptions cleaned up.

Replace Docker-based builds with Nix flakes for reproducible builds.
Changes:
- Use nixos/nix:latest image with `nix` tag requirement
- Build Docker image with `nix build .#dockerImage`
- Add optional Cachix integration for binary caching
- Load image with `docker load < result`
- Keep existing deploy stage unchanged
Benefits:
- Reproducible builds across all environments
- Binary caching via Cachix (faster subsequent builds)
- All dependencies pinned in flake.lock
- Image size similar to Docker builds (~507 MB compressed)
Requirements:
- GitLab Runner with Nix installed and `nix` tag
- Docker socket mounted for loading/pushing images
- Optional: CACHIX_AUTH_TOKEN for binary caching
See docs/gitlab-runner-nix-setup.md for runner setup instructions.
The old Docker-based config is available in git history if rollback needed.
Comprehensive documentation covering architecture, usage, technical
details, and future enhancements for the job monitoring dashboard.

- Add UserSudoController with GET and POST /users/sudo/verify routes
- Create verify.html.heex template for TOTP verification form
- Only accept TOTP codes (6 numeric digits), reject recovery codes
- Update grant_sudo_mode to set authenticated_at virtual field
- Exclude /users/sudo paths from return_to overwriting
- Add comprehensive controller tests (12 test cases)
- Verify redirect behavior, error handling, and session management

The plug was incorrectly placed in the endpoint, causing it to run on
all requests including APIs. Moved to :browser pipeline where it belongs,
and removed redundant fetch_session call since the pipeline handles it.
Documents the root cause analysis and solution for the Valkey pod
restart issue. The problem was a race condition during node restarts,
not a Flannel failure.
Resolution:
- Added system-cluster-critical priority class to Valkey
- Application-level Redis health checks provide additional resilience
- Monitoring ongoing to verify stability over 24-48 hours
