      Based on this article from cloudbees, I had the following in /etc/sysconfig/jenkins:

      JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Duser.timezone=America/Los_Angeles -Dorg.apache.commons.jelly.tags.fmt.timeZone=America/Los_Angeles -XX:+AlwaysPreTouch -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/jenkins/ -XX:+UseG1GC -XX:+UseStringDeduplication -XX:+ParallelRefProcEnabled -XX:+DisableExplicitGC -XX:+UnlockDiagnosticVMOptions -XX:+UnlockExperimentalVMOptions -Xlog:gc*,gc+heap=trace,gc+age*=trace,gc+ref*=trace,gc+ergo*=trace:file=/var/log/jenkins/gc-%t.log:utctime:filecount=2,filesize=100m -XX:ErrorFile=/var/log/jenkins/hs_err_%p.log -XX:+LogVMOutput -XX:LogFile=/var/log/jenkins/hs_%p.log"

      The relevant part there seems to be:

      -Xlog:gc*,gc+heap=trace,gc+age*=trace,gc+ref*=trace,gc+ergo*=trace:file=/var/log/jenkins/gc-%t.log:utctime:filecount=2,filesize=100m

      When I upgraded to 2.332.2, the migration moved these values to /etc/systemd/system/jenkins.service.d/override.conf, but the service failed to start, with the following output from journalctl -xe:

      Apr 08 21:07:49 ip-10-0-0-74.ec2.internal jenkins[7288]: [0.001s][error][logging] Error opening log file '/var/log/jenkins/gc-/run.log': No such file or directory

Apr 08 21:07:49 ip-10-0-0-74.ec2.internal jenkins[7288]: Error: A fatal exception has occurred. Program will exit.

      I think this is because of the %t in the trace:file path, which adds a timestamp to the file name. That substitution doesn't seem to work after the migration to systemd.

      I've submitted feedback to cloudbees as well, and it seems to have been updated on another page that deals with these options.
