Description

This can be a problem on nodes hosting a lot of VMs with Rudder for example, because the cf-promises check is quite cpu-intensive.

Currently the check script is run every 5 minutes in a cron job:

0,5,10,15,20,25,30,35,40,45,50,55 * * * *

We need to avoid this problem by:

  • using the same frequency as the agent run
  • start it at different times (using a kind of splay time like the regular agent)

We have added a random sleep before check in #14258, this should not occur anymore.
