When to restart Sensu

Question

When must the sensu-client be restarted? I've noticed that I can just restart the sensu-api and sensu-server and new checks that I add seem to work. Do I need to restart clients like the doc says?

Answer 1

I think the answer is no. You only have to restart clients when adding new configurations to them. Otherwise they'll automatically pick up new checks that the server dictates.

Answer 2

For the most part configuration management tools will restart the right components when necessary.

The clients do need to be restarted when client-side configuration (standalone checks, rabbitmq, etc) changes.

Also, the servers themselves need their local clients restarted (if you are running a sensu client on your sensu server too), even when server-side definitions are changed, due to this bug: https://github.com/sensu/sensu/issues/806
