As a follow-up to my most recent blog, the approach to setting up Nagios the networking monitoring tool on a cluster of ARM machines has changed. As a result of this, I am now focusing my efforts on setting up a Nagios master and client on a couple of x86_64 systems, using yum packages, instead of the initial installation and configuration using source tarball files. The perception going in using this new approach, was this is going to be a walk in the park (easy), not quite the outcome so far. Well on the bright side I have a master and client setup, and live via the web, however I have had some difficulties getting both machines to complete a monitoring transactions between each other. Current challenge revolves around the inability of the Nagios master to access the nrpe daemon processes on the client machine; in an effort to indentify what potential problems exist on the client. The errors that I continue to receive, directs me to believe that the nrpe plugins are not stored in what should be its correct location, based on the following error message --> (Return code of 127 is out of bounds - plugin may be missing). The truth of the matter is that the plugin are stored in the correct directory path location.
As always there continues to be some type of issue when installing these different packages on a system, with the objective of getting it working as it should. I will continue to work towards working out these ongoing kinks. I have taken the liberty to offer a couple screenshots of my initial progress. I will check back in very soon to offer details of my progress with this project.
