Satellite Health Check?

Hi everyone,

I hope you are all fit and well.

Can someone help me to run the icinga check. I went here: icinga but no information on how to run the check.
I am logged in to a satellite server and want to run a few checks to see if master/satellite is set up correctly as I have a Master => Satellite in Top Down configuration by following the docs here: Top Down

What can I run on the command line of a Master/Satellite to confirm I have configured the Satellite correctly?

Thanks in advance
Pete
