Steps to Install Nagios Remote Plug-ins Execution (NRPE) daemon
The Monitored (target) host was running Redhat and the Monitoring (source) host was running Ubuntu.
Install (Target)
- yum -y install nagios-nrpe.x86_64
Configure (Target)
- Edit /etc/nagios/nrpe.cfg
- Update: allowed_hosts to include (Source) host that will execute nrpe
Start and Update startp (Target)
- service nrpe start
- chkconfig nrpe on
Validate (Source)
In this case my monitoring host was an Ubuntu Server. Install the following on monitoring server:
- aptitude -y install nagios-nrpe-server
- aptitude -y install nagios-nrpe-plugin
From monitoring (Ubuntu) host run:
- /usr/lib/nagios/plugins/check_nrpe -H <hostname>
You should get a response such as: NRPE v2.14
