/mcpthan the default threshold value unintentionally, change the value to default. Also, examine the trace and log file setting for each of the application in trace configuration page under CCM Serviceability. If the number of configured traces / logs is set to greater than 1000, adjust the trace settings from trace configuration page to default. Also, clean up the trace files that are less than a week old. You can clean up the traces using cli "file delete" or using Remote Browse from RTMT Trace and Log Central function. Error Message %UC_LPMTCT-4-SparePartitionHighWaterMarkExceeded: %[UsedDiskSpace=String] [{Optional}MessageString=String][AppID=String][ClusterID=String][NodeID=String]: The percentage of used disk space in the spare partition has exceeded the configured high water mark.. Explanation The percentage of used disk space in the spare partition has exceeded the configured high water mark. Some of the trace files will be purged until the percentage of used disk space in the spare partition gets below the configured low water mark Recommended Action Login into RTMT and cheek the configured threshold value for SparePartitionHighWaterMarkExceeded alert in Alert Central. If the configured value is set to a lower than the default threshold value unintentionally, change the value to default. If you continue to receive this alert for half an hour after receiving the 1st alert, check for the disk usage for Spare partition under "Disk Usage" tab in RTMT. If the disk usage shown under that tab is higher than configured value in SparePartitionLowWaterMarkExceeded alert configuration, contact Cisco TAC to troubleshoot the cause of high disk usage in Common partition. Error Message %UC_LPMTCT-4-AuditLogOverflowDueToLPMPurge: %[AppID=String][ClusterID=String] [NodeID=String]: Indicates that application audit log files have been deleted by Log Partition Monitor(LPM). Explanation This alarm indicates an overflow occurred due to purge by LPM clean up logic. When the total disk space usage of log partition crosses the high water mark configured, the LPM tool's clean up logic deletes the oldest files from the log partition so that the new logs can be written. Recommended Action Login to " Cisco Unified Serviceability - > Tools - > Audit Log Configuration " page and check if the purging is enabled. You can choose not to delete the audit log files by LPM by disabling the " Enable Purging " option. Error Message %UC_CALLMANAGER-2-CallManagerFailure: %[{Optional}Text=String][HostName=String] [IPAddress=String][Reason=Enum][AppID=String][ClusterID=String][NodeID=String]: Indicates an internal failure in Unified CM. Explanation This alarm indicates that an internal failure occurred in the Cisco CallManager service. The service should restart in an attempt to clear the failure. Recommended Action Monitor for other alarms and restart Cisco CallManager service, if necessary. Collect the core file if available, SDL and CCM/SDI trace files (you can gather these from Trace and Log Central in RTMT using the Collect Files feature) and contact the Cisco Technical Assistance Center (TAC).
