Controller's CPU stats

  • 1.  Controller's CPU stats

    Posted Feb 28, 2012 01:19 PM

    I've noticed that AirWave's monitor shows the Supervisor Card's CPU at an average of 64% and the graph shows a constant spike every few minutes from 20% to 99%.  When ever I pull up Controller Summary on the controller it shows the controller utilization at 0%.  

     

    Which of these should I trust more?

     

    Just as a note I'm running a 6000 controller with a supervisor 1 card on Aruba OS 5.0.4.1.  Airwave is version 7.4.7.

     

    Thanks!

    Airwave is probably accurate. If I had to guess, your CPU is going up when Airwave polls the controllers, every 5 minutes. You can test this theory by clicking the Poll Now button, and see if it creates another spike in CPU.
