Processor
The processor object provides information on different processor time usage in percentages. Table 5-56
contains information on processor counters.
Process Status This counter displays the process status:
•
0—Running
•
1—Sleeping
• 2—Uninterruptible disk sleep
•
3—Zombie
• 4—Stopped
•
5— Paging
•
6—Unknown
Shared Memory Size This counter displays the amount of shared memory (KB) that a task is using.
Other processes could potentially share the same memory.
STime 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.
Thread Count 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.
Total CPU Time Used 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.
UTime This counter displays the time, measured in jiffies, that a task has scheduled in
user mode.
VmData This counter displays the virtual memory usage of the heap for the task in
kilobytes (KB).
VmRSS 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.
VmSize 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.
Wchan This counter displays the channel (system call) in which the process is waiting.
