I'm managing a large cfengine installation and am trying to use a
SplayTime of 120 minutes across the hosts, along with a schedule
parameter to tell cfexecd when to run.
I *want* cfexecd to "start" on all the systems at 6AM, then have all the
systems wait for up to 120 minutes to actually do the work, thus evenly
distributing the load over a 2 hour period.
I've got
SplayTime = ( 120 )
in update.conf, and
schedule = ( Hr06.Min00_05 )
in cf.classes (included by cfagent.conf). This has the following strage
result: it runs cfagent on all the systems spread evenly between the two
5-minute windows between 6:00 - 6:05 and 7:00 - 7:05. This isn't quite
what I had in mind.
If I change the schedule parameter to something like ( Hr06 ), then
cfagent runs repeatedly on the system during the 6AM hour. This isn't
correct either.
What magic incantation do I have to do to make cfexecd "kick off" at 6AM
and spread the load out over two hours, with it running just once per day?
