Use NSClient++ with librenms

Help
1

Does anyone have or know of a good tutorial on how to integrate NSClient++ with LibreNMS and the nagios plugins. Ive got it setup on my server and see data in the web interface, Im just stalling on how to get librenms to pull the data or have NSClient++ send the data to Librenms

I’ve also added nagios-nrpe-server and can verify a connection to the client with NSClient++ on it.

I looks like you’re on the right track but I think the rest might be a bit more manual than you were hoping for.

I don’t use NSClient++ but as I understand it, it has a a number of builtin NRPE checks. Do you get data back if you query those with check_nrpe? For example…

./check_nrpe -H 192.168.1.100 --command check_memory

If so you just need to add each of the NRPE checks that you want to monitor as its own service using with the command switch (--command check_memory) in the service’s parameters field.
