Say I turn on the splay option for a puppet agent with:
sudo puppet config set splay true --section agent
Then I run:
/usr/local/bin/puppet agent --onetime --no-daemonize
From what I understand splay causes the check-in time to randomised.
I'm wondering how this randomness is calculated? Is it a random time in the next, hour, day, week, or something else?
I'm reading here, that the default time is randomised between the time the command is run and 2 minutes after that.
When the service is stopped, the selected nodes will randomly stagger the start of their runs (“splay”) over a default interval of two minutes. If you wish, you can specify special options, including a longer interval (“splaylimit”). You can also set the force option to true if you want the selected nodes to start immediately. This behavior is more flexible and resilient.
The 2 minutes can be modified with:
LIMIT=60
sudo puppet config set splaylimit $LIMIT --section agent
