![]() ![]() We need plugins to check on the status of services and metrics as explained in the above paragraph. Remember that without Nagios plugins, you can only monitor whether a host or device connected to the network is up or down. In this guide we will dive more deeply into Nagios Core plugins and what you can do with them.Īdditionally, we will introduce you to NRPE (Nagios Remote Plugin Executor), an utility that will allow you to run Nagios Core plugins remotely both in Linux and Microsoft Windows machines to check metrics such as disk space usage and CPU load. Under the hood, plugins are an abstraction layer that link the Nagios daemon and the hosts and services being monitored. ![]() ![]() In our previous article (“ Nagios Core Installation and Configuration on Ubuntu Server“), we defined Nagios Core plugins as extensions (either in the form of compiled binaries or executable scripts) that process command-line arguments, perform specific checks, and then return the results to the main program. With our straightforward tutorials, you will be able to get your own projects up and running in minimum time. We cover a wide range of topics, from installation and configuration, to plugins and NRPE. In this course, we provide a compilation of Nagios tutorials that will help you set up your own monitoring infrastructure. ![]() OK: 0 total health issue(s) found - All ESX hosts are ok | 'total_problems'=0 0 1034 'problems_'=0 0 315 'problems_yellow_'=0 0 315 'problems_red_'=0 0 315 'problems_'=0 0 315 'problems_yellow_'=0 0 315 'problems_red_'=0 0 315 'problems_'=0 0 202 'problems_yellow_'=0 0 202 'problems_red_'=0 0 202 'problems_'=0 0 202 'problems_yellow_'=0 0 202 'problems_red_'=0 0 202Ĭhecking host ''ģ15 health checks are green, 0 total health issue(s) found, 0 yellow health issue(s) found, 0 red health issue(s) foundĬhecking host ''Ĭhecking host ''Ģ02 health checks are green, 0 total health issue(s) found, 0 yellow health issue(s) found, 0 red health issue(s) foundĬhecking host ' article is part of our Academy Course titled Nagios Tutorial for IT Monitoring. $ perl centreon_ -plugin=apps::vmware::connector::plugin -connector-hostname=127.0.0.1 -container=default -verbose -mode=health-host -esx-hostname='.*' -filter -disconnect-status='ok' Please follow the documentation for the installation: ExamplesĬheck vmtools states of virtual machines (with name matching the regexp 'prd'): It means: i can check the virtual machines of a datacenter(s) and/or a cluster(s).
