Monitoring via NRPE

As I mentioned earlier, a number of plugins, such as check_memory, collect information from the system itself, which means that they cannot be directly used for monitoring remote systems.

NRPE runs on the machine that you'd like to monitor and executes the same commands/plugins which Nagios itself would have. Nagios is then configured to collect data from NRPE rather than collecting data directly.

How to do it…
