Garbage Collection JVM arguments

[Shane Rand]

Has anyone had any luck with the options suggested here: https://confluence.atlassian.com/jirakb/using-garbage-collection-logs-to-analyze-jira-application-performance-227416009.html

I've added the arguments as they are listed (and confirmed our logs are in the default location).

I can see that the setenv.sh file has the new JVM args in there and a third party JVm analyzer also sees them. I do not however see any new logs for garbage collection at the specified location. I can confirm that garbage collection is occuring.

Anyone have any thoughts/ideas on this?

Hi Shane,

You can upgrade JIRA to JIRA 7.5 - the newer version of JIRA has these JVM set by default and you should be getting all the logs by default.

For your current problem, I would check:

1. Have you restarted JIRA after the changes in setenv.sh file?
2. File system permission.
3. Have you defined Xloggc correctly?
4. Navigate to System Info page in your JIRA and find for JVM Input Arguments. Do you see the JVM argument? If no, then you have done it some wrong in specifying the JVM argument. 

I hope that this helps. Cheers!
