Subject Re: incorrect cpu usage values in dashboard
Date Tue, 15 Oct 2013 09:29:31 GMT
Hi Valery,
you will see incorrect values until the capacity checker runs again. By default i think it
runs every 5  min.
you can change the interval at which capacity checker runs by changing the capacity.check.period

global config.
