Where are you guys seeing docs for this "H Token" thing? Can you send a specific URL? (Google didn't find it for me and Jenkins "?" doesn't show it as an option.)

If you only had one job to run, 'H/15 * * * *' would run it every fifteen minutes, but that could either be :00, :15, :30, :45 or :04, :19, :34, :49, or something like that. If you have a bunch of different jobs to schedule every fifteen minutes but don't want them to all kick off at the same time, then giving them all H/15 schedules would give each job a fifteen-minute schedule. On average, they'd scatter around that period for even loading, but you might get unlucky and have them all end up with the same schedule. If you really want to enforce even loading, maybe you want to use the same nodes for them all and just limit the number of executors on those nodes. If you have ten of these fifteen-minute jobs and only want one to run at a time, point them all to a one-galleon node. Even if they all kick off at once, they'll still only run one at a time. But they might not run in the same order all the time, so you could have five or twenty-five minutes between runs depending on the scheduler. If you really, really want to enforce even loading with every-fifteen-minute running times, I think you're going to have to go "longhand", decide which ones launch on which minute, and set them up by hand. I believe the cron entries would be like: */15 * * * * # :00, :15, :30, :45 1-59/15 * * * * # :01, :16, :31, :46 2-59/15 * * * * # :02, :17, :32, :47 etc. --Rob From: jenkinsci-users@googlegroups.com<mailto:jenkinsci-users@googlegroups.com> [mailto:jenkinsci-users@googlegroups.com] On Behalf Of Octavian Covalschi Sent: Wednesday, February 13, 2013 5:06 PM To: jenkinsci-users@googlegroups.com<mailto:jenkinsci-users@googlegroups.com> Subject: Periodic even build question Hello, I'm trying to setup periodic builds for a few dozens of jobs, but in the same time I'd like to even the load... so for example, I need to run them at every 15min, but would like to even the load... is it possible? I saw the 'H' token, but I'm not sure If it can help me... The closest valid syntax I was able to put together is: H(0-14),H(15-29),H(30-44),H(45-59) * * * * But, I don't thinks it's what I need, since the 1st H may trigger it at min 13 and 2nd H may trigger it at min 16, so I'll get 3 min interval, but I need ~15 Thank you in advance. -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
