I am using “chef-client” cookbook (depends ‘chef-client’, ‘~> 10.0.4’).
The interval of each chef-client run is controlled by “default[‘chef_client’][‘interval’]”.
So I have set my interval to 300 seconds as the below:
# Sets Chef::Config[:interval] via command-line option for number of seconds between chef-client daemon runs. Default 1800. default['chef_client']['interval'] = '300'
Also there is a delay can be added on top of this interval:
# Sets Chef::Config[:splay] via command-line option for a random amount of seconds to add to interval. Default 300. default['chef_client']['splay'] = '60'
So I expected to see chef-client run in between 5 to 6 mins?
However when I checked my RHEL7 message log output, to my surprise I found out that some of the chef-client run interval can be up to 7mins instead of up to 6mins.
The log says:
Jun 27 09:32:25 sg-mr-chef chef-client
Jun 27 09:39:18 sg-mr-chef chef-client
Jun 27 09:45:48 sg-mr-chef chef-client
Jun 27 09:53:03 sg-mr-chef chef-client
Jun 27 09:59:26 sg-mr-chef chef-client
Jun 27 10:06:37 sg-mr-chef chef-client
Jun 27 10:13:07 sg-mr-chef chef-client
It clearly shows some of the interval is more than 6mins. Is this expected?
