Issue:

  After enabling Agent Autonaming of TIBCO Instance, the CPU usage is very high (~99%) .

  Once the correct name is acquired, CPU Usage reached to normal .

Environment:
APM 10.5.xTIBCO BW
Cause:

Caused by Permgen space using 99%.

Resolution:

 Workaround is to increase the PermGen in JVM argument.

 

 Add Java option to set max PermGen:
-XX:PermSize=256M -XX:MaxPermSize=256M

 

 Example of JVM Argument of Server Startup script:

 

java.extended.properties=-javaagent:/opt/wily/introscopeagent/10.5.2.15 /Agent.jar - Dcom.wily.introscope.agentProfile=/opt/wily/introscopeagent/10.5.2.15/core/config/IntroscopeAgent.tibcobw.profile -XX:PermSize=256M -XX:MaxPermSize=256M
