问题
When looking at the status tab in the chef server webgui I see some of my nodes have a last check-in of a few minutes ago, even though I haven't ran chef-client in them for days. Does that mean chef-client is running by itself in some nodes?
Thanks
回答1:
It's the last time a "node" (server) sent information to the Chef Server. It's like a healthcheck.

This isn't quite on topic, but it supports some responses I have seen in this post: You can always add the Chef community "chef-client" cookbook to your role or run_list and it will ensure all nodes check in on an attribute specified fuzzy schedule.
knife cookbook site install chef-client
knife cookbook upload chef-client
knife node run_list add $node chef-client
