Works great

Thanks. I’m running on remote PI.

On the remote Pi you install NRPE: apt-get install nagios-nrpe-server

Configure NRPE like so: vi /etc/nagios/nrpe.cfg

…
allowed_hosts=
…
command[check_temp]=/path/to/check_rpi_temp.sh -w 60 -c 70
…
On the Nagios server configure the check like so:

check_command check_nrpe!check_temp
