3CX monitoring for MSPs
If you manage more than a handful of 3CX systems, logging into each one is not a monitoring strategy — and it will not tell you where a number goes after five. Kestrel is the partner board: fleet, call-flow map, alerts.
What 3CX monitoring should mean for a partner
Which boxes are up, where a DID actually lands, whether trunks are registered, whether licenses are about to become a problem, whether a backup is stale, whether a production update is waiting, and whether the data is fresh.
What Kestrel watches
- Inbound call flow: trunk → DID → IVR / queue / ring group / extension, with hours filter
- Reachability and last-good poll time
- Concurrent calls vs licensed SC, plus 30/90-day peaks and charts 1h–90d
- Office hours mode (business hours, after hours, holiday)
- Trunk registration, backup age, available 3CX updates, and What changed since the last snapshot
- Inventory: extensions, trunks, DIDs, inbound rules, SBCs, companies
How Kestrel reaches 3CX
Cloud poller over HTTPS to the Configuration API on 3CX v20+ systems that allow it. Service principal preferred. Owner-password fallback. No outbound connector agent.
