Using the CLI to Troubleshoot Problems

If you experience any problems with your controller, you can use the commands in this section to gather
information and debug issues.

OL-17037-01
System Messages and Descriptions (continued)
show process cpu—Shows how various tasks in the system are using the CPU at that instant in time.
This command is helpful in understanding if any single task is monopolizing the CPU and
preventing other tasks from being performed.
Information similar to the following appears:
Name Priority
reaperWatcher ( 3/124)
osapiReaper (10/121)
TempStatus (255/
emWeb (255/
cliWebTask (255/
UtilTask (255/
In the example above, the following fields provide information:
The Name field shows the tasks that the CPU is to perform.
•
The Priority field shows two values: 1) the original priority of the task that was created by the
•
actual function call and 2) the priority of the task divided by a range of system priorities.
The CPU Use field shows the CPU usage of a particular task.
•
The Reaper field shows three values: 1) the amount of time for which the task is scheduled in
•
user mode operation, 2) the amount of time for which the task is scheduled in system mode
operation, and 3) whether the task is being watched by the reaper task monitor (indicated by a
"T"). If the task is being watched by the reaper task monitor, this field also shows the timeout
value (in seconds) before which the task needs to alert the task monitor.
If you want to see the total CPU usage as a percentage, enter the show cpu command.
