CloudBees Jenkins Enterprise

CloudBees Jenkins Operations Center

Operating System: Windows


Request the jenkinsjmap.bat script via a Support Ticket.

Your environment should be configured as documented in Prepare Jenkins For Support.

If you are experiencing high Java heap utilization please collect the following data
while the issue is occurring:

  1. Generate a Support Bundle.

  2. Run the jenkinsjmap.bat as an administrator in one of the following modes:

    • ./jenkinsjmap.bat PID - for default mode which generates jmap -heap output and jmap -histo output

    • ./jenkinsjmap.bat PID 1 - for heapdump mode which generates jmap -heap output, jmap -histo output, and a heapdump file binary format

    • The data will be generated in the same directory where the script is ran.

  3. Upload the Support Bundle to your support ticket for review. Compress the data generated by the jenkinsjmap.bat script and upload
    it via our upload site. Please update your support ticket with the name of the file. Please note that the Support Core plugin v2.35
    and higher will include the verbose gc logs.
    If you are using an older version please include the verbose gc logs in the compressed
    data uploaded to our upload site.
