This is now started using launchd from ~glastrm/Library/LaunchDaemons/monitor-jenkins.plist, but does not start automatically after a reboot. Instructions to start:
ssh glastrm@ppa-pc90719 (password in escrow as macglastrm) ppa-pc90719:~ glastrm$ cd /Users/glastrm/Library/LaunchDaemons ppa-pc90719:LaunchDaemons glastrm$ launchctl load monitor-jenkins.plist ppa-pc90719:LaunchDaemons glastrm$ launchctl start monitor_jenkins
