check_jmx was designed to work with the native Java RMI . Jolokia provides an endpoint that returns JSON data, which is not data in a form that the JRMP recognizes as indicated by the exception thrown (non-JRMP server at remote endpoint). Therefore, pointing it at a Jolokia endpoint will result in e...

That is not how the logstash-output-csv plugin works. This plugin takes events that are in the Logstash pipeline, and writes them out to CSV. It can't work with results that are currently stored in Elasticsearch. As mentioned in the other thread, if you can navigate Elasticsearch queries well enough...

Which device would you choose to start installing the operating system before you install the Nagios Core? If you have a virtualization environment available, I would slap Nagios Core on a VM so you can version it and have a more accessible dev->test->prod workflow for your critical monitoring infr...

It would be useful to understand virtualization in general. High level overview type stuff though, nothing super specific. Depending on the hypervisor you're using for your virtual machines (stuff like VMWare, Hyper-V, VirtualBox, etc), you could probably find a ready-to-go template for Nagios XI th...
