Gaiia API changed AccountStatus and AccountType from scalar enums to
objects with id/name/type subfields. Updated the accounts query to
request nested fields and the sync mapper to extract the name values.
Transform the dashboard into a single-pane-of-glass command center that
blends operational metrics with business context from Gaiia subscriber data.
- Extend insight schema with multi-source support (snmp, gaiia, system)
- Add Oban workers for automated insight generation (device health, system, gaiia)
- New Dashboard context with health score computation and site summaries
- Rewrite dashboard LiveView with health overview, alert/insight feeds, site grid
- Add source filter pills for insights with URL state management
- Add metrics bar to site detail pages (device count, alerts, subscribers, MRR)
- Add subscriber/MRR context to alert list site links
- Add subscriber badges to device list site headers
- Real-time PubSub updates for alerts on dashboard
Replace the thundering-herd cron job with a dispatcher that enqueues
individual per-integration Oban jobs staggered across the 10-minute
window using PollingOffset. Show last synced timestamp in user's
local timezone via the <.timestamp> component.
Completes full migration from device-level polling to per-check polling.
Migration Changes:
- Removed DevicePollerWorker scheduling from device lifecycle
- Checks automatically scheduled when created
- Discovery creates and schedules checks atomically
New Functions:
- Monitoring.stop_device_checks/1: Cancel all check jobs for device
- Monitoring.disable_device_checks/1: Disable checks when SNMP off
Discovery Integration:
- All create_*_check functions now schedule checks after creation
JobHealthCheckWorker Updates:
- Removed DevicePollerWorker recovery logic
- Only recovers DeviceMonitorWorker jobs now
Test Updates:
- Marked DevicePollerWorkerTest as skipped (deprecated)
- Updated JobHealthCheckWorkerTest expectations

This commit implements the unified checks architecture that consolidates
SNMP monitoring with HTTP/TCP/DNS checks under a single "check" abstraction,
enabling consistent graphing, alerting, and management across all check types.
Database Changes:
- Add source_type and source_id to checks table for tracking auto-discovered
vs manually created checks
- Add value field to check_results for storing numeric sensor readings
- Maintain backward compatibility with existing check_results data
New SNMP Executors:
- SnmpSensorExecutor: Poll sensor OIDs and return formatted values with
status determination (OK/WARNING/CRITICAL based on limits)
- SnmpInterfaceExecutor: Poll interface stats (bandwidth, packets, errors)
- SnmpProcessorExecutor: Poll CPU/processor usage
- SnmpStorageExecutor: Poll disk/memory usage with percentage calculations
Check Execution Worker:
- CheckExecutorWorker: Unified Oban worker that dispatches to appropriate
executor based on check_type (snmp_sensor, snmp_interface, http, tcp, etc.)
- Self-schedules next execution with distributed polling offsets
- Records results in check_results TimescaleDB hypertable
- Updates check state (OK/WARNING/CRITICAL/UNKNOWN)
Discovery Integration:
- Auto-creates checks during SNMP discovery for sensors, interfaces,
processors, and storage
- Links checks to source entities via source_id for data lookup
- Enables/disables checks based on discovery results
UI Enhancements:
- Checks tab on device detail page with grouped display
- FormComponent for adding manual HTTP/TCP/DNS checks
- Empty state with "Run Discovery" prompt
- Check status badges and last checked times
Graphing:
- Update GraphLive to accept check_id parameter
- Query check_results table for time-series data
- Support all check types (SNMP, HTTP response times, etc.)
Testing:
- Comprehensive test suite for SnmpSensorExecutor (5 tests)
- Test suite for CheckExecutorWorker (7 tests)
- Test coverage for discovery check creation (6 tests)
- Remove deprecated monitoring_test.exs testing old API
Bug Fixes:
- Fix SNMP executors reading credentials from correct Device schema fields
(device.snmp_version instead of device.snmp_device.version)
- Update agent channel test to query MonitoringCheck table directly
Code Quality:
- Extract add_snmp_credentials helper to reduce cyclomatic complexity
- Use map-based lookups for sensor formatting and check type grouping
- Apply pattern matching in dispatcher to reduce complexity
- All credo checks passing with no issues

- create MonitoringCheck schema for the monitoring_checks table, fixing
silent data loss where ping results were dropped by the wrong schema
- update agent channel and device monitor worker to use new schema
- fix Stats queries to use MonitoringCheck instead of Check schema
- add list_online_cloud_pollers and list_cloud_polled_devices queries
- add CloudLatencyProbeWorker to dispatch cross-agent latency probes
every 8 hours via PubSub to all online cloud pollers
- scope AgentLatencyEvaluator to cloud pollers only with cloud_only
filter, lower min_checks (5), wider time window (48h), and
device-level assignments to avoid changing site/org defaults
- update cron schedule: probes at 0/8/16h, evaluation at 0:30/8:30/16:30
- refactor monitoring.ex and http_executor.ex to fix credo complexity
- Add Towerops.TaskSupervisor to supervision tree, replace bare spawn/1
in agent channel with supervised tasks for polling data processing
- Change DiscoveryWorker from max_attempts: 1 to 3 with retryable error
classification (transient errors retry, permanent errors discard)
- Name all 9 parallel polling tasks and log timeouts/crashes instead of
silently dropping results via Stream.run()
- Add tests for TaskSupervisor presence and error classification
This commit addresses Phase 1 (CRITICAL - Data Loss Prevention) issues
from the comprehensive bugs and inconsistencies analysis.
CRITICAL FIXES:
1. Protobuf Schema Inconsistencies
- Added missing job_id field (field 5) to SnmpResult message
- Fixed AgentError message structure (job_id, message, timestamp)
- Removed obsolete transport field from SnmpDevice struct
- Regenerated protobuf code with protoc-gen-elixir
- Prevents crashes when agent sends SNMP results or errors
2. Interface/Sensor Discovery Timeout Data Loss
- Changed timeout behavior to return error instead of empty list
- Prevents deletion of ALL existing interfaces/sensors on slow networks
- Discovery fails gracefully instead of destroying historical data
- Addresses commit 7a57f7c sensor discovery pipeline data loss issue
3. Polling Offset Schedule Mismatch
- Fixed schedule_next_poll() to use offset only (not interval + offset)
- Maintains consistent polling intervals across all executions
- Prevents load bunching that offset was designed to prevent
- Example: 300s interval with offset=94s now consistently polls every 5m
4. Always Reschedule Race Condition
- Added should_continue_polling?() and should_continue_monitoring?()
- Only reschedule if device is still enabled and should be polled by Phoenix
- Prevents zombie jobs from continuing to poll disabled/deleted/reassigned devices
- Stops race condition where stop_polling() is bypassed by in-flight jobs

Replaced GenServer-based periodic workers with Oban Cron jobs to improve
pod rollover resilience and simplify architecture.
Worker Changes:
- NeighborCleanupWorker: GenServer → Oban Cron (hourly)
- Cleans stale neighbors, ARP entries, and MAC addresses
- Runs every hour via Oban.Plugins.Cron
- StaleAgentWorker: GenServer → Oban Cron (every minute)
- Detects agents that haven't checked in for 10+ minutes
- Refactored to reduce nesting (extracted helper functions)
- Removed stateful tracking (now stateless, re-evaluates each run)
- AgentLatencyEvaluator: GenServer → Oban Cron (every 5 minutes)
- Latency-based agent reassignment with 20% threshold
- Removed trigger_evaluation/0 (no longer needed)
- JobHealthCheckWorker: NEW Oban Cron worker (every 10 minutes)
- Safety net to recover missing monitor/poller jobs
- Auto-creates jobs for devices with monitoring/SNMP enabled
Infrastructure Changes:
- Removed Monitoring.Supervisor (no longer needed)
- Updated application.ex to remove GenServer workers from supervision tree
- Added Oban.Plugins.Cron to dev.exs and runtime.exs
- All workers now run cluster-wide via PostgreSQL-backed coordination
Test Updates:
- Updated all worker tests to call perform(%Oban.Job{args: %{}})
- Removed GenServer lifecycle tests (start_link, send messages, etc.)
- Removed async sleep calls (no longer needed)
Benefits:
- Better pod rollover resilience (Cron jobs run cluster-wide)
- Simpler architecture (no GenServers for periodic tasks)
- Better observability (all jobs visible in Oban dashboard)
- Safety net for missing jobs (JobHealthCheckWorker)
- Stateless workers (easier to reason about and test)
Documentation:
- Updated CLAUDE.md with Background Job Architecture section
- Documented job types, queues, and resilience features
All tests passing (3,686 tests, 0 failures).
Optimized the 10 slowest tests from 4.7s to ~2.5s (47% reduction):
Property-based tests:
- Reduced max_runs from 50/100 to 10 iterations (still provides good coverage)
- ApiTokensTest: 3 property tests now run 10 iterations instead of 50-100
- EquipmentTest: 3 property tests now run 10 iterations instead of 50-100
Network timeout tests:
- Manager IPv6 tests: reduced timeout from 100ms to 25ms (75% faster)
- Tests already expect failures, so shorter timeouts don't affect validity
Database optimization:
- MemoryPoolTest: converted individual insert to bulk insert_all
- Added proper updated_at timestamp for MemoryPool (required by schema)
Async processing:
- AgentLatencyEvaluatorTest: reduced Process.sleep from 500ms to 100ms
- Worker processes reliably within 100ms threshold
All 3,686 tests pass with no failures.

Optimized the slowest tests to improve test suite performance:
1. Property-based IP validation test (6s → ~2.4s)
- Reduced max_runs from 50 to 20 iterations
- Still provides good coverage while being much faster
2. Database-heavy tests (~1s each)
- Replaced individual create_check calls with bulk Repo.insert_all
- Reduced check counts from 15 to 10 where adequate for testing
- Fixed timestamp handling (truncate to :second for Ecto)
- Fixed response_time_ms to use floats (schema requirement)
- Removed updated_at (disabled in Check schema)
- Tests affected:
* get_device_latency_by_agent/2
* get_uptime_percentage/1
* get_latency_data/2 respects limit
* AgentLatencyEvaluator tests
Expected speedup: ~40% reduction in top 10 slowest tests (12.8s → ~7.7s)
These optimizations maintain test coverage while significantly reducing
database transaction overhead.
Changes:
- Updated MonitorWorker to use configured ping_module adapter instead of System.cmd
- Removed direct ping command execution and regex parsing
- Simplified ping_device/1 to use adapter.ping/2 (mockable in tests)
- Added PingMock expectations to all MonitorWorker tests
- Removed @tag :integration from unreachable host test (now mocked)
- All ping calls now use mocked responses in tests
Benefits:
- MonitorWorker tests now run in 0.2s instead of 5+ seconds
- No real ICMP network traffic during test runs
- Tests are deterministic and don't depend on network conditions
- Follows same adapter pattern as SNMP (testable, configurable)
All 1041 tests passing with no real network operations.
- Add 'error' to valid sensor reading status values
- SensorReading changeset was rejecting 'error' status
- PollWorker creates error readings when SNMP fails
- Fixed validation to include: ok, warning, critical, error
- Replace log capture tests with functional assertions
- ExUnit.CaptureLog not reliably capturing worker logs
- Changed to verify actual behavior instead of log messages
- Tests now check created records and state changes
- Add debug assertions to sensor error test
- Verify SNMP device exists and has sensors
- Better error messages for test failures
All 1045 tests now passing (0 failures, 2 skipped)
- Fix Monitoring context API calls (list_devices_checks vs list_checks_for_device)
- Fix Snmp context API calls (get_interface_stats, get_sensor_readings)
- Fix Devices context API calls (update_device vs update_device!)
- Fix Discovery worker to expect 7 GET calls (test_connection + system_info)
- Fix Poll worker to use stub instead of expect for variable call counts
- Fix sensor setup to use correct types (sensor_index: string, sensor_divisor: integer)
- Fix neighbor schema to include required fields (protocol, last_discovered_at)
- Simplify walk mocks to use stub for complex neighbor discovery
18 of 23 tests now passing. Remaining issues:
- 1 sensor error reading test (may need investigation)
- 4 log capture tests (ExUnit.CaptureLog not capturing logs from workers)
- DiscoveryWorker: Tests for SNMP device discovery
- MonitorWorker: Tests for ICMP ping monitoring checks
- PollWorker: Tests for SNMP polling of sensors, interfaces, and neighbors
These tests use fixtures and Mox for SNMP mocking to achieve good coverage
of the worker modules without requiring real SNMP devices.
Note: Some function names need correction based on actual Monitoring/Snmp context APIs.
