Periodic 100% cpu with Hyperic Agent

Sounds like Hyperic is scanning your servers every 15 minutes. What configuration settings is Hyperic checking, and can they be refined to have less of an impact?

• You could try monitoring fewer settings on one of the servers to see if it has an effect.
• It's also possible that another process is reading the registry and or file system at the same time as Hyperic. You might try disabling unnecessary services to see if that reduces CPU load.

I had a similar issue with hyperic 4.1.1. After running fine for 2+ years, we started seeing high cpu use.

We isolated the issue to the agent. In our case, we were using the agent with the embedded jre.

We installed the v6 build 35 jre, and set HQ_JAVA_HOME :

(Note: Do not set this var to the java bin dir. Rather set it to the base jre6 dir, on windows this is typically: c:\program files\java\jre6 )

We restarted the agent, and there is peace on earth!
