Chapter 5 Cisco Unified Real-Time Monitoring Tool Tracing, PerfMon Counters, and Alerts Performance Monitoring in RTMT Table 5-55 Process (continued) Counters Process Status Shared Memory Size STime Thread Count Total CPU Time Used UTime VmData VmRSS VmSize Wchan Counter Descriptions This counter displays the process status: • 0-Running • 1-Sleeping • 2-Uninterruptible disk sleep • 3-Zombie • 4-Stopped • 5- Paging • 6-Unknown This counter displays the amount of shared memory (KB) that a task is using. Other processes could potentially share the same memory. This counter displays the system time (STime), measured in jiffies, that this process has scheduled in kernel mode. A jiffy corresponds to a unit of CPU time and gets used as a base of measurement. One second comprises 100 jiffies. This counter displays the number of threads that are currently grouped with a task. A negative value (-1) indicates that this counter is currently not available. This happens when thread statistics (which includes all performance counters in the Thread object as well as the Thread Count counter in the Process object) are turned off because the system total processes and threads exceeded the default threshold value. This counter displays the total CPU time in jiffies that the task used in user mode and kernel mode since the start of the task. A jiffy corresponds to a unit of CPU time and gets used as a base of measurement. One second comprises 100 jiffies. This counter displays the time, measured in jiffies, that a task has scheduled in user mode. This counter displays the virtual memory usage of the heap for the task in kilobytes (KB). This counter displays the virtual memory (Vm) resident set size (RSS) that is currently in physical memory in kilobytes (KB). This includes the code, data, and stack. This counter displays the total virtual memory usage for a task in kilobytes (KB). It includes all code, data, shared libraries, and pages that have been swapped out: Virtual Image = swapped size + resident size. This counter displays the channel (system call) in which the process is waiting. Processor The processor object provides information on different processor time usage in percentages. Table 5-56 contains information on processor counters. OL-22523-01 Cisco Unified Communications Manager Managed Services Guide 5-71
