Chapter 3 Managing and Monitoring the Health of Cisco Unified Communications Manager Systems RTMT Monitoring of Cisco Unified CM System Health Figure 3-5 VmSize listed by RTMT Process Possible memory leak causes can be from the VmSize continuously increasing. When a process leaks memory, the system administrator should report it to Cisco and include trace files. RIS Data Collector PerfMonLog collects the data and it contains historical information on memory usage. Disk Usage There are four disks or partitions in the Cisco Unified CM hard drive: • Common partition (log partition)-Contains the trace/log files • Active partition-Contains files (binaries, libraries and config files) of active OS and the Cisco Unified CM release • Inactive partition-Contains files for alternative Cisco Unified CM release (for example, an older version that was upgraded from or newer version recently upgraded to but the server has not been toggled to this release). • Swap partition-Used for swap space Using SOAP APIs, you can get partition information for the following perfmon counters: • Under Partition object-Total Mbytes, Used Mbytes, Queue Length, Write Bytes Per Sec, Read Bytes Per Sec Using the SNMP MIB, you can query the following information: • Host Resource MIB-hrStorageSize, hrStorageUsed hrStorageAllocationUnits, hrStorageDescr, hrStorageType You can download the following historical information by using RTMT Trace and Log Central: • Cisco AMC Service PerfMonLog // enabled by default. Deprecated in Cisco Unified CM 6.0, because Cisco RIS Data Collector PerfMonLog is introduced • Cisco RIS Data Collector PerfMonLog // disabled by default in Cisco Unified CM 5.x; enabled by default in Cisco Unified CM 6.0 Figure 3-6 shows disk usage by partition in RTMT.
