Nitin Mehta commented on CLOUDSTACK-187:
----------------------------------------

Vladimir - I think you are confusing the allocated capacity of cloudstack with the real time usage. Refer to the wiki - https://cwiki.apache.org/CLOUDSTACK/understanding-dashboard.html
I think the basis of this bug is incorrect and so I am resolving it as wont fix.  If you disagree please feel free to reopen.

> CloudStack reports incorrect CPU & RAM usage values for hosts in Basic zone.
> CPU usage is reported about 90%, when "top", XenCenter and other tools report that actual usage is about 1%.
> The "command=listCapacity&zoneid=1&type=1" returns something like "<percentused>90.49</percentused>".
> The only way I found to get rid of this, is to:
> * place the host into Maintenance mode,
> * remove it from its Cluster,
> * add the host again.
> After this procedure, correct values are reported.
> Interesting that in my practice it happens thrice for hosts in Basic zone, and never - for hosts in Advanced.
