In our previous tutorial, we learnt how to install Nagios NRPE Agent on RHEL/CentOS/Oracle Linux. Well, for NRPE to collect various performance metrics on the system, it requires the Nagios plugins. Step through this guide in order to install Nagios Plugins.
Download Nagios Plugins Source code
Download the latest version of Nagios plugins from here. You can simply run the following command to download the plugins.
# wget https://nagios-plugins.org/download/nagios-plugins-2.2.1.tar.gz
Once the download is complete, run the command below to extract the source code.
# tar xzf nagios-plugins-2.2.1.tar.gz
Configure the Plugins
Once you have extracted the source code, navigate to the source code directory and run the configure script to initialize variables and create a Makefile, etc as shown below.
NOTE: Before you can proceed with the following steps, ensure that the gcc compilers are installed.
# cd nagios-plugins-2.2.1 # ./configure
