This article intends to give the reader a brief introduction on how to install and configure the EPEL upstream version of the NRPE agent on Debian Linux 6, 7, 8 and Ubuntu 16.04.2 LTS.<\/p>\n
\n

Historically, OP5 has compiled and packaged the NRPE agent for a large number of Linux distributions, but as per Q2 2014 we stopped doing this since it required a lot of maintenance and time. More information on this decision can be found here: https:\/\/www.op5.com\/blog\/blogs\/op5-developers-blog\/deprecation-notices-q2-2014\/<\/a><\/p>\n

<\/p>\n
\n

Note that this article is intended for Debian 6, 7, 8 and Ubuntu 16.04 client hosts, and that these steps never should be performed on an OP5 Monitor server.<\/p>\n<\/div>\n<\/div>\n

 <\/p>\n

1. Install the NRPE package together with plugins:<\/p>\n

\n
<\/div>\n<\/div>\n

# apt-get install nagios-nrpe-server nagios-plugins-basic<\/p>\n

2. Create a new file called \/etc\/nagios\/nrpe.d\/op5_commands.cfg containing the following information:<\/p>\n

\n
\n<\/code><\/p>\n<\/div>\n<\/div>\n

These paths to the plugins should match the paths to the installed plugins in step 1.<\/p>\n

 <\/div>\n

3. Now edit \/etc\/nagios\/nrpe.cfg and add your Monitor server(s) address(es) to the allowed_hosts parameter as a comma-separated list in the appropriate section:<\/p>\n

\n
<\/div>\n<\/div>\n
\nallowed_hosts=127.0.0.1,10.0.0.10,10.0.0.11<\/pre>\n
4. Restart the nrpe agent on the host:<\/p>\n
\n
<\/div>\n<\/div>\n
\n\n# \/etc\/init.d\/nagios-nrpe-server restart<\/pre>\n
Now you can add the services via the function "Add UNIX client services" when adding a host in op5 Monitor.<\/p>\n
<\/p>\n
\n
If the host is behind a firewall, or you have enabled firewall software on the host, you need to open for incoming traffic on TCP port 5666.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
