/mcpNote: Adding vDisk is not supported as it would require re-partitioning by the application. If the storage configuration is not aligned with the requirements, you must rebuild the VM with the correct OVA template. Log Partition Monitoring Tool Log Partition Monitoring Tool (LPM) uses configured thresholds to monitor the disk usage of the log partition on a server every 5 minutes. There are two alerts you can configure on RTMT to modify this thresholds: LogPartitionLowWaterMarkExceeded (% disk space)—When the disk usage is higher than the percentage that you specify, LPM sends out an alarm message to syslog and an alert to RTMT Alert central. To save the log files and regain disk space, you can use trace and log central option in RTMT. 1. LogPartitionHighWaterMarkExceeded (% disk space)—When the disk usage is higher than the percentage that you specify, LPM sends an alarm message to syslog and an alert to RTMT Alert central. When this threshold value is reach the older log files are purged, and this creates additional disk space in the logging partition. 2. To purge files, please refer to Adjust WaterMark in RTMT of Call Manager Procedure Guide. Execute Free Space COP File If common partition space is not enough after adjusting High/Low WaterMark values, proceed to install the latest Cisco Free Common Space COP file. Warning: You must install the patch during a maintenance window because the installation during normal business hours temporarily impacts the system performance. Ensure that you install the patch when there is no other CLI or GUI activity on the system because the patch terminates all CLI and GUI sessions and restarts the Tomcat service.
