Windows: Time service (w32time) peer summary status

Included in	All Checkmk editions
Source Code License	Open Source
Supported Agents	Windows

This check monitors the configured time synchronization peers in the Windows time service (w32time) as a singular summary service.

A ruleset, "Windows time service peers summary" exists where alerting can be configured in multiple ways, e.g., reporting on when a peer's stratum changes, when the last several consecutive attempts to communicate with the peer have failed, or when some number of attempts out of the last (not necessarily consecutive) tries to contact the server have failed. See the help text in the ruleset for more information.

If the service is configured to only alert if all hosts cross the defined thresholds, then the service status will only change if every peer would otherwise be in WARN or CRIT state, and the worst state will be reflected as the service state.

Discovery

One summary service is created. If you wish to have one service per peer, use the NTP Discovery ruleset on this host to configure that.
