wrong cpu utilization

[no-smoke]

Hello,
i installed the netxms agent on two linux servers (Ubuntu Server 12.04 LTS) and on both servers the netxms agent gives a wrong number of cpu in the system an a wrong cpu utilization. Everytime there is one missing cpu and the cpu utilization is too high. When the server shell with the command top says there is cpu utilization of 10% netxms still says 51%. During hours the utilization changes a bit, but everytime arround 50% and wrong.

How can I resolve the problem.
The load is of the cpu is correct.

Hi!

I've found a bug in CPU usage calculation code. Fix will be included in 1.2.9 release.
