LogPartitionHighWaterMarkExceeded—Occurs when the percentage of used disk space in the log
•
partition has exceeded the configured high water mark. When this alert is generated, Log Partition
Monitoring (LPM) utility starts to delete files in Log Partition until the Log Partition is down to the
low water mark to avoid running out of disk space. Since LPM may delete some files that you want
to keep, you need to act upon receiving LogPartitionLowWaterMarkExceed alert.
LowActivePartitionAvailableDiskSpace—Occurs when the percentage of available disk space of the
•
Active Partition is lower than the configured value. Please use the default threshold that Cisco
recommends. At default threshold, this alert should never be generated. If this alert occurs, a system
administrator can adjust the threshold as temporary workaround but Cisco TAC should look into
this. One place to look is /tmp using remote access. We have seen cases where large files are left
there by 3rd party software.
LowInactivePartitionAvailableDiskSpace—Occurs when the percentage of available disk space of
•
the InActive Partition is lower than the configured value. Please use the default threshold that Cisco
recommends. At default threshold, this alert should never be generated. If this alert occurs, a system
administrator can adjust the threshold as temporary workaround but Cisco TAC should look into
this.
