Extended agent polling to collect all available SNMP data during regular
polls, not just sensors and interfaces. This ensures data stays current
and reduces reliance on periodic discovery runs.
Changes:
- Added polling queries for: neighbors (LLDP/CDP), ARP tables, MAC tables,
IP addresses, HOST-RESOURCES processors and storage
- Process additional data using Replay adapter pattern to reuse existing
parsing logic from discovery modules
- Made discovery helper functions public for reuse in polling context:
save_neighbors/2, save_arp_entries/3, sync_ip_addresses/2,
sync_processors/2, sync_storage/2
- Optimized by fetching interfaces once and reusing across operations
- Fixed compilation warnings by using proper guard syntax (list != [])
Technical details:
- Detection threshold: polls with more OIDs than sensors+interfaces
are processed for additional data
- Background processing: spawns async process to avoid blocking metric
recording
- Replay adapter: allows reusing discovery parsing logic without
re-querying SNMP device
