The My Data page had tabs in a different order (Security before Sessions)
than the main settings page, and tab links used JS.push which never fired
because navigate does a full page load. Now both pages share the same tab
order and links include proper ?tab= query params.
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
the catch-all error handler was silently discarding the error reason,
making it impossible to debug failures. add logging and a specific
handler for graphql validation errors.
the viewer query doesn't exist in gaiia's schema, causing a 400
validation error. use a minimal accounts query instead. also handle
400 responses with graphql errors properly.
Three write-back capabilities: ticket creation from alerts, subscriber
notes during outages, and inventory item updates. Adds GraphQL mutation
methods to the client and an Actions module that handles credential
retrieval and API call orchestration.
Computes subscriber impact when device alerts fire. Three analysis
layers: device-level (inventory item -> direct subscriber) and
site-level (network site -> all subscribers at tower). Impact data
stored as JSONB on alert records and displayed as badges on alert list.
Stage 4 of Gaiia integration: when a device is mapped to a Gaiia
inventory item, show a Gaiia tab with inventory details, linked
subscriber info, billing subscriptions, network site, and IP
mismatch indicators.
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.
the default base url was pointing at the docs site
(apidocs.preseem.com) instead of the actual api endpoint
(api.preseem.com), causing all api calls to fail with
unauthorized. removed the unnecessary base_url user override
since the api endpoint is fixed.
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
All 6953 tests passing, 0 failures

Completes Phase 5 of the unified checks system by enabling automatic check
creation during SNMP discovery and providing a backfill tool for existing devices.
Discovery Integration:
- create_checks_from_discovery/2: Creates checks for all discovered entities
(sensors, interfaces, processors, storage) after SNMP discovery completes
- Links each check to its source entity via source_id for data lookup
- Returns detailed results with counts per type and error tracking
- Logs creation results with total counts and any failures
Helper Functions:
- create_sensor_check/2: Creates snmp_sensor checks with config
- create_interface_check/2: Creates snmp_interface checks
- create_processor_check/2: Creates snmp_processor checks
- create_storage_check/2: Creates snmp_storage checks
All checks configured with:
- 60-second poll intervals (default)
- Auto-discovery source type
- Enabled by default
- Type-specific configuration in JSONB config field
Backfill Tool:
- mix backfill.checks: Creates checks for existing SNMP-enabled devices
- Supports --dry-run mode for preview
- Shows counts per device (sensors, interfaces, processors, storage)
- Reports success/failure counts and detailed errors
- Safely handles devices without discovery data
- Reduced nesting depth using cond and helper functions for credo compliance
This enables the unified monitoring system to work with both new discoveries
and existing devices, ensuring all SNMP data can be monitored through the
unified checks interface.

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 'Checks' tab link to device navigation
- Display empty state when no checks configured
- Add tests for tab visibility and empty state
- Fix unused variable warnings in monitoring context
- Remove unused CheckResult alias and module attributes
- Add stub for legacy get_latency_data for backward compatibility
Tests: 2 new tests added, all passing
Following TDD: RED-GREEN cycle verified for each feature
Enhanced AgentChannel logging to track device IDs across job list updates.
Added tests verifying server correctly excludes deleted devices from job lists.
Root cause: Bug is in Go agent (appends jobs without clearing), not Phoenix server.
Implements Icinga2-style generic check system for comprehensive monitoring.
Phoenix Backend:
- Generic checks table with JSONB config for all check types
- TimescaleDB check_results hypertable for time-series data
- Check executors (HTTP, TCP, DNS)
- CheckWorker with self-scheduling and state transitions
- Extended alerts system for check-based alerting
Check Types: HTTP/HTTPS, TCP, DNS
Architecture: Icinga2 Checkable pattern, soft/hard states, flapping detection
