Grep shows me (on Debian Stable, puppet 2.6.2) that agent.rb sets up an event loop: /usr/lib/ruby/1.8/puppet/agent.rb /usr/lib/ruby/1.8/puppet/external/event-loop/event-loop.rb > 2. How can we change its calculation? (can we edit a file, run a > command, �?) Subclass the event loop or the agent perhaps? (I'm assuming that the several existing techniques for changing agent run times are insufficient for you.) > On Nov 3, 2011, at 8:38 AM, Nigel Kersten wrote: > > On Thu, Nov 3, 2011 at 8:36 AM, Jo Rhett > <[2]jrh...@netconsonance.com> wrote: > > For a long time it appeared that run cycles were fairly balanced > -- a few every 30 seconds over the 30 minute period.
