Question & Answer
Question
Is there a very simple method to collect basic information on DataPower CPU utilization and memory usage?
Answer
Yes. CPU and memory information can be captured every 5-10 seconds by creating a logging target in the default domain with the correct event subscriptions.
In the Web GUI, in the default domain:
In the Web GUI, in the default domain:
- Choose Administration from the navigation list on the left, and then look under heading Device
- Choose Statistics Settings and make sure statistics are enabled.
- Choose Throttle Settings and turn the Status Log option on by clicking on the On radio button
- Create a logging target in the default domain
- A File type log target with a file name in the logtemp:/// folder or on the RAID drive is recommended to allow log entries to be written locally to the appliance with very low overhead.
- Add the following Event Subscriptions to the logging target:
system debug slm debug
- The logging target file will contain information about CPU and Memory statistics
- The logging target will contain message 0x80400051 showing CPU information. The CPU message is logged every ten seconds.
20210218T193749.848Z [0x80400051][system][debug] : tid(143): cpu usage: 1%(10 sec) 0%(1 min) 0%(10 min) 0%(1 hour) 0%(1 day) 20210218T193759.849Z [0x80400051][system][debug] : tid(143): cpu usage: 0%(10 sec) 0%(1 min) 0%(10 min) 0%(1 hour) 0%(1 day)
- The logging target will contain message 0x804000a1 showing memory information. This message is logged every 5 to 10 seconds:
