See the same results on a lenovo laptop with quad core i7 (/proc/cpuinfo shows four of the following: Intel(R) Core(TM) i7 CPU M 620 @ 2.67GHz). Hi David Thanks for the bug report. Can you supply some more info: -Full version of EWS being monitored -Java version running JON agent and Java version running EWS -Can you attach a copy of the inventory.xml from underneath the JON agent install -How long does the high CPU load last? Where in the agent's directory structure should the inventory.xml file be located? I ran a find in both locations and nothing came up. As for the other questions: On RHEL6 VM: EWS 1.0.2 java version "1.6.0_24" Java (TM) SE Runtime Environment (build 1.6.0_4-b07) Java HotSpot (TM) 64-Bit Server VM (build 19.1-b02, mixed mode) On lenovo laptop running Fedora 15: EWS 1.0.2-RHEL6-i386 java version "1.6.0_22" OpenJDK Runtime Environment (IcedTea6 1.10.6) (fedora-63.1.10.6.fc15-i386) OpenJDK Server VM (build 20.0-b11, mixed mode) CPU load seems to continue indefinitely, as long as those EWS/Tomcat metrics are enabled. Even after disabling them, I had to restart the agent service in order for CPU usage to subside (note that restarting the service involved invoking rhq-agent-wraper.sh on the server/laptop. Simply restarting the agent through the JON server UI didn't work). Created attachment 577812 [details]
inventory.xml from lenovo
Sorry, forgot you have to generate the inventory.xml file. I uploaded the file for the lenovo. I'll upload it for the VM in a bit. Created attachment 577819 [details]
RHEL VM inventory file
This has been fixed upstream. See bug 812968. As this is MODIFIED or ON_QA, setting milestone to ER1. bug was verified in upstream, re-tested with jon 3.2 er1 - no regression (only during the start/restart the cpu usage is high and then it gets back to ~1.2%) |
