Nagios check for T-Rex miner.

T-Rex API must be opened in a secured way:

• --api-read-only: accessible only in read-only, no modification
• --api-bind-http 127.0.0.1:4067: (default) accessible only to local connections

If the check is executed remotely, you should add a firewall rule to allow only the host running the check to access the T-Rex API port.

HTTPS should be used:

• --api-https
• --api-webserver-cert
• --api-webserver-pkey

See full list of options.
