how to check runtime for chef-client executions

Question

• We are using an open-source chef server managing about 150 nodes.
• Analytics/Reporting module is not activated in the chef server due to resource constraints.
• "chef-client" is running on all the nodes every 30 minutes

I want to know what's the runtime for each node to complete their chef-client run.

Answer 1

 Chef doesn't have the mechanism to save this info. You need to this yourself by using a handler like docs.chef.io/handlers.html#id3 . You can make a handler which stores the duration of the last run as node attribute.
