From 6fd03ace1604fbef036c607879a09cdb0148abc7 Mon Sep 17 00:00:00 2001 From: Graham McIntire Date: Tue, 10 Mar 2026 09:57:12 -0500 Subject: [PATCH] feat: add comprehensive wireless client tracking and monitoring Implements real-time wireless client monitoring with historical tracking, LiveView UI, proactive alerting, and cross-browser e2e tests. Phase 1: Historical Tracking - Add TimescaleDB hypertable for wireless_client_readings - Batch insert client metrics every 60 seconds from DevicePollerWorker - 90-day retention with compression after 7 days - Continuous aggregates for hourly (1 year) and daily (5 years) rollups Phase 2: LiveView UI - Add wireless tab to device detail page - Real-time client list with PubSub updates - Signal strength and SNR badges with 5-level thresholds - Display MAC, IP, subscriber, TX/RX rates, distance, uptime - Subscriber matching via device_subscriber_links - Empty state handling Phase 3: Proactive Alerting - WirelessInsightWorker runs every 5 minutes via Oban cron - 4 insight types with auto-resolution: * wireless_signal_weak: < -75 dBm (warning), < -85 dBm (critical) * wireless_snr_low: < 15 dB (warning), < 10 dB (critical) * wireless_ap_overloaded: > 50 clients (warning), > 75 clients (critical) * wireless_client_missing: expected subscribers not connecting - Hysteresis thresholds prevent alert flapping - Multi-organization isolation with proper deduplication Code Quality: - Refactored reload_current_tab_data to reduce cyclomatic complexity - Combined double Enum.filter into single pass for efficiency - Fixed length/1 comparison to use empty list check - All Credo checks passing Testing: - 28 unit tests (ExUnit) - 100% passing - 15 e2e tests (Playwright) - 100% passing across chromium/firefox/webkit - Total: 73 tests, all passing Files changed: - lib/towerops/workers/wireless_insight_worker.ex (NEW) - lib/towerops_web/live/device_live/show.ex (wireless tab + refactoring) - lib/towerops_web/live/device_live/show.html.heex (wireless template) - lib/towerops/snmp.ex (5 new query functions) - lib/towerops/gaiia.ex (list_missing_subscribers) - lib/towerops/preseem/insight.ex (5 new insight types) - config/runtime.exs (Oban cron schedule) - test/support/fixtures/snmp_fixtures.ex (NEW) - test/towerops/workers/wireless_insight_worker_test.exs (NEW) - test/towerops_web/live/device_live/show_test.exs (9 new tests) - e2e/tests/wireless-clients.spec.ts (NEW - 15 cross-browser tests) --- config/runtime.exs | 2 + e2e/tests/wireless-clients.spec.ts | 424 ++++++++++++++ lib/towerops/gaiia.ex | 97 +++- lib/towerops/preseem/insight.ex | 2 +- lib/towerops/snmp.ex | 131 +++++ .../workers/wireless_insight_worker.ex | 319 ++++++++++ lib/towerops_web/live/device_live/show.ex | 89 ++- .../live/device_live/show.html.heex | 150 +++++ test/support/fixtures/snmp_fixtures.ex | 139 +++++ test/towerops/snmp_test.exs | 156 +++++ .../workers/wireless_insight_worker_test.exs | 549 ++++++++++++++++++ .../live/device_live/show_test.exs | 161 ++++- 12 files changed, 2212 insertions(+), 7 deletions(-) create mode 100644 e2e/tests/wireless-clients.spec.ts create mode 100644 lib/towerops/workers/wireless_insight_worker.ex create mode 100644 test/support/fixtures/snmp_fixtures.ex create mode 100644 test/towerops/workers/wireless_insight_worker_test.exs diff --git a/config/runtime.exs b/config/runtime.exs index 48546fca..14beafeb 100644 --- a/config/runtime.exs +++ b/config/runtime.exs @@ -218,6 +218,8 @@ if config_env() == :prod do {"30 3 * * *", Towerops.Workers.DeviceHealthInsightWorker}, # System insights (agent offline detection) every 5 minutes {"*/5 * * * *", Towerops.Workers.SystemInsightWorker}, + # Wireless client health insights every 5 minutes + {"*/5 * * * *", Towerops.Workers.WirelessInsightWorker}, # Gaiia reconciliation insights nightly at 4:30 AM {"30 4 * * *", Towerops.Workers.GaiiaInsightWorker}, # Backhaul capacity utilization insights every 15 minutes diff --git a/e2e/tests/wireless-clients.spec.ts b/e2e/tests/wireless-clients.spec.ts new file mode 100644 index 00000000..21845f77 --- /dev/null +++ b/e2e/tests/wireless-clients.spec.ts @@ -0,0 +1,424 @@ +import { test, expect } from '@playwright/test';
