SSL Checker Service not listed


Basically, I’m wanting to monitor a few websites we run to check and notify when SSL certs are about to expire or expired.

Validate says everything is ok.

Here is what I’ve done:
sudo apt install monitoring-plugins
chmod +x /usr/lib/nagios/plugins/*

After I installed the plugins I don’t see the ssl checker but do have a lot more options now.

Any idea what I’m missing? Thanks
