Getting CPU Utilization in BigIP

According to the SDK documentation:

 

STATISTIC_TM_TOTAL_CYCLES - Total CPU cycles spent in traffic management.

 

STATISTIC_TM_IDLE_CYCLES - CPU cycles spent polling with no traffic.

 

STATISTIC_TM_SLEEP_CYCLES - CPU cycles yielded to other processes (uniprocessor only).

 

 

The actual CPU cycles spent handling traffic is Total - (Idle + Sleep).

 

These numbers are cumulative since startup. The difference over an interval should be used to get the current load.

 

 

The method used to get these statistics is System::Statistics::get_global_statistics

 

 

You should get some data back when calling this method, since the stats are cumulative since startup. What do you get for these stats (under TMM cycles) when doing a "bp global show" on the CLI? Do you get anything?

 

 

Please note that these statistics only relate to CPU utilization pertaining to traffic management, not the host's CPU utilization. Host's CPU utilization statistics are not available at this time.
