Anyone using Simon for monitoring servers?

Anyone out there using Simon for server monitoring?

I have a license but haven’t ever gotten into it, and it looks fairly complicated, but there doesn’t seem to be much by the way of tutorials online… so I’d like to find other users, if there are any out there.

I have not used Simon. I have used Sensu for server monitoring, if you are under 1000 hosts you can use the free version. There is good documentation and and lots of monitoring options.
