Synchronization of Operating System Time
|Distribution||Official part of Checkmk|
|Supported Agents||Windows vSphere|
Its advantage however, is that it works on any Windows or ESX host - regardless of the method used to synchronize the time.
Levels can be set for making the check warn/crit if the time difference exceeds the configured limits.
One service is created for each host supporting this check.
