Nagios Queries

[Mathew Walker]

typically the remote linux server runs NRPE ... it can be installed relatively easily via most package managers and/or source.

Subject: [Nagios-users] Nagios Queries

Hello,

I'm currently running Nagios 3.0 on CentOS and was curious if anyone can tell me (in Service Detail) how (without plugins) that Nagios is able to query remote Linux boxes and gather information such as Current Load, Root Partition, Swap Usage, Total Processes, etc...

I do not recall doing anything special that would allow this info to be returned...is it possible that the remote Linux box has a service that Nagios tries to connect?  

Basically Nagios was setup to just monitor, which I figured it would only be successful with pings, however it's obviously gathering much more info.

Any help would be great...also if there is a better way to gather data, that would be helpful too.

thanks in Advance!
