The snmp plugin registers list_snmp_devices and get_snmp_device; the prometheus plugin registers list_prometheus_targets and get_prometheus_target. Both are viewer-level, read what the poller and scraper stored, and exist only while their plugin is enabled. get_overview names a device or target whose last poll or scrape failed; stale, pending and off are left out. A device's community and v3 keys and a target's token are never returned, and a password in a target URL is masked. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
