CPU Load on Jboss Cluster EAP 6.1, it's too high.

[Alejandro Llanes]

Hi there,

I've configured zorka agent in two jboss cluster nodes, at the beginning all is fine but after 2 or 3 hours has passed, we perceive an increment on cpu load. I had to disable the agent in the server because the cpu usage reach the 100% and doesn't decrement. Once I started the server without the zorka agent, the performance became normal.

The monitoring with zorka agent it's amazing, lots and lots of useful information; but for the performance troubles we cannot have the agent enabled.

So, if anyone can help me with problem would be great.

Thanks beforehand.

Hi,

This is strange behavior. I'm not aware of any bug like this. Two things need to be checked:

1) If memory runs out - constant 100% CPU is often symptom of lack of memory, please check memory metrics of JBoss process;

2) If memory indicators are OK, please check which threads consume whole CPU: Zorka agent adds 'ZORKA-' prefix to all its threads;
