I have the follow alarm in the RTMT tool:
SeverityMatch : Critical
MatchedEvent : Feb 20 08:37:24 CUCM-PUB local7 2 LpmTool: 3846: CUCM-PUB: Feb 20 2017 11:37:24.316 UTC : %UC_LPMTCT-2-LogPartitionHighWaterMarkExceeded: %[UsedDiskSpace=68][MessageString=Common Disk utilization hits HWM!!

That's just a warning, based on the % you have your alert configured to, logs get generated all the time and they will not go beyond that limit and will be deleted. To "fix" this, you'd need to disable logs/traces in your server or keep deleting them manually.
As I mentioned, logs will keep being generated, unless you want to disable them, that is something that pretty much anyone will see at some point in time, you can increase the % for that alert as well, you'll just get the alert at a higher %
You can try this... Change the low water mark to 30 and the high water mark to 45. Leave it for 1hr. Cucm will automatically purge log files and traces and that will free up space in your common partition. The alert should clear after this time. Then change is back to between 80 and 85 or whatever value you want
To free some space in the Common partition, you can try to:
