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.
