Monitoring Processes and CPUs
• Z—Defunct (“zombie”) process.
• NR—Not running.
• ER—Should be running but is currently not running.
Note The ER state typically designates a process that has been restarted too many times, causing the system
to classify it as faulty and disable it.

Displaying CPU Utilization
Use the show processes cpu command to display CPU utilization. See Example 2-2. The command
output includes the following:
• Runtime(ms)—CPU time the process has used, expressed in milliseconds.
• Invoked—Number of times the process has been invoked.
• uSecs—Microseconds of CPU time in average for each process invocation.
• 1Sec—CPU utilization in percentage for the last one second.
Example 2-2 show processes cpu Command
switch# show processes cpu
PID Runtime(ms) Invoked uSecs 1Sec Process
