Issue #14766 has been updated by Matthaus Owens.
Released in Puppet 3.2.0-rc1 ---------------------------------------- Bug #14766: 2nd puppet run after restart is ignoring runinterval, negating splay https://projects.puppetlabs.com/issues/14766#change-89536 * Author: Mariusz Gronczewski * Status: Closed * Priority: Normal * Assignee: Andrew Parker * Category: agent * Target version: 3.2.0 * Affected Puppet version: 2.7.14 * Keywords: customer * Branch: https://github.com/puppetlabs/puppet/pull/1130 ---------------------------------------- after upgrading from 2.7.13 to 2.7.14 I noticed that our puppets got "synchonized" and we have 10-20 clients running in one minute but 1-2 in other, which causes big spikes in load, especially if it hits few VMs on same physical machine It seems that second puppet run after splay ignores runinterval: May 13 05:00:03 blade308 puppet-agent[8820]: Sleeping for 346 seconds (splay is enabled) # start May 13 05:05:49 blade308 puppet-agent[8820]: Retrieving plugin # puppet run 5m after start May 13 05:10:02 blade308 puppet-agent[8820]: Finished catalog run in 106.23 seconds May 13 05:30:17 blade308 puppet-agent[8820]: Retrieving plugin # puppet run 25m after last one, 30m after start May 13 05:37:28 blade308 puppet-agent[8820]: Finished catalog run in 107.28 seconds May 14 05:00:04 blade308 puppet-agent[17967]: Sleeping for 1019 seconds (splay is enabled) May 14 05:17:03 blade308 puppet-agent[17967]: Retrieving plugin # puppet run 17 min after start May 14 05:21:03 blade308 puppet-agent[17967]: Finished catalog run in 99.93 seconds May 14 05:30:16 blade308 puppet-agent[17967]: Retrieving plugin # puoer run 13 min after last one 30m after start May 14 05:37:21 blade308 puppet-agent[17967]: Finished catalog run in 103.47 seconds It seems like 2nd run is counting time from puppet start, not from last run For comparision, before update: Apr 29 04:03:09 blade307 puppet-agent[31595]: Sleeping for 723 seconds (splay is enabled) Apr 29 04:15:12 blade307 puppet-agent[31595]: Retrieving plugin # 12m after start Apr 29 04:19:54 blade307 puppet-agent[31595]: Finished catalog run in 127.66 seconds Apr 29 04:50:21 blade307 puppet-agent[31595]: Retrieving plugin # 35m after last run, 47 after start. Apr 29 04:54:27 blade307 puppet-agent[31595]: Finished catalog run in 95.67 seconds I noticed that now it counts run interval from start of puppet, not from end of last run. While it makes puppet run in interval closer to defined run interval, it causes problems when for some case puppet will be ran at same time on many nodes. Before every "peak" in load would cause puppet run to take longer so next run would be delayed, causing 'peak time' to smooth out after few runs. -- You have received this notification because you have either subscribed to it, or are involved in it.
