Summary

By default, the Atlassian-garbage collection logs include the date in their description when the JVM is initialized(For example, when Jira is restarted). 

Example:

atlassian-jira-gc-2021-03-12_15-45-25.log.0.current

If you would like to remove the date, you will need to modify the file responsible for the Garbage collection log parameters. 

(warning) Please note that with GC log rotation(enabled by default), these files will be overwritten causing loss of historical GC data. If you would like to retain historical data, please do not remove the date parameter from the Garbage collection logs. 

Solution

  1. Shutdown Jira
    1. For Jira Data Center, shut down all nodes
  2. Navigate to /<Jira-installation-dir>/bin/set-gc-params.sh
    1. For Windows the file is set-gc-params.bat
  3. Modify the section:
    1. From: -Xloggc:$LOGBASEABS/logs/atlassian-jira-gc-%t.log
    2. To : -Xloggc:$LOGBASEABS/logs/atlassian-jira-gc.log
    3. Remove the -t%
  4. Start Jira
  5. The file format will now be atlassian-jira-gc.log.0.current
