SeverityMatch : Critical
MatchedEvent : Jun 25 11:36:05 CUCMPUB user 2 platform: The local NTP client is off by more than the acceptable threshold of 3 seconds from its remote NTP system peer. The normal remedy is for NTP Watch Dog to automatically restart NTP. However, an unusual number of automatic NTP restarts have already occurred on this node. No additional automatic NTP restarts will be done until NTP time synchronization stabilizes. This is likely due to an excessive number of VMware Virtual Machine migrations or Storage VMotions. Please consult your VMware Infrastructure Support Team.
We do not use VMotion on our UCS gear and have checked to ensure NTP is in sync.
