Use Windows Process Explorer to troubleshoot Jira server Performance
This article outlines a way to analyze JIRA application performance using Process Explorer on Windows. You'll need to collect thread dumps and correlate that with the thread IDs from Process Explorer.
This will only work for Windows systems and requires the use of a third-party application.
For *nix system please see Troubleshoot Jira Server performance with thread dumps. Another option for a high level overview is Using jvmtop to analyze JIRA performance.
- Download Process Explorer and run it on the server JIRA application is installed;
This is a third-party application, and as such it's not supported by Atlassian.
- Locate the
tomcat.exeprocess, which is the application server that serves JIRA application;
- Right-click the process and select Properties.
- Go to the Threads tab to get an overview of the running threads within the process.
The first column is the thread ID (TID) and the second column is the CPU utilization for each thread. Notice that the thread ID (TID) in Process Explorer is in Decimal format and corresponds to NID in the thread dumps. NID in thread dumps is in hexadecimal, so you will need to convert decimal to hexadecimal to identify those threads
- With this information, we can now see which threads are consuming the most CPU and relate with what's being performed by each, as reported in the thread dumps;
Providing Information to Support
Atlassian Support may request thread dumps when troubleshooting JIRA application. Adding additional information showing which threads are consuming the most CPU may considerably expedite the troubleshooting process.
