The partition alerts are as follows:

• LogPartitionLowWaterMarkExceeded—Occurs when the percentage of used disk space in the log

partition has exceeded the configured low water mark. This alert should be considered as early

warning for an administrator to clean up disk space. You can use RMT Trace/Log Central to collect

trace/log files and then delete these trace/log files from the server. In addition to manually clean up

the traces/log files, the system administrator should also adjust the number of trace files to be kept

to avoid hitting low water mark again.

• 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.
