monitoring openshift 4 vms

[noamyiz]

Hallo, Nagios forum board people,
Currently have at my company an Openshift 3.11 cluster running as predicted on RHEL VMS in vCenter. monitoring those machines isn't hard using the NCPA agent, but soon we're about to upgrade to Openshift 4 which is using CoreOs servers restricting us from installing the agent on the VMS.
Is there a way you see fit to continue monitoring our infrastructure using Nagios XI and the NCPA agent? Is Nagios planning on creating an openshift\kubernetes operator or a custom wizard to the Configuration Wizards page?
Also just as an extra question, is there a Nagios XI redesign coming soon? And if so when? (possibly Nagios XI 6?)

Thanks for any help in advance,
Noam

P.S. running in on-prem environment and Nagios xi instance running from ova template

Hi @noamyiz,

Welcome to the Nagios Support Forum!

What types of checks are running with NCAP, and are you using any additional plugins installed directly on those servers? Let me know and I will look around to see what's currently available. If you cannot install an agent, then the options are check by ssh, using an API or SNMP.

Yes, Nagios XI, 6 will be out later this year and will include significant enhancements to the GUI, dashboards, and reporting (see https://www.nagios.com/roadmaps/). I'm not sure if an openshift\kubernetes is configuration wizard is being planned but I can check with the development team on this one for you.

Best Regards,
Benjamin

Hi @benjaminsmith,
Thanks for the reply, we are currently checking for the basic VM metrics: cpu, ram, disk, etc.
Connecting using ssh is available only to a main server from which you can connect to the cluster nodes, will be checking using SNMP. Using API is possible but it's through the cluster software itself and I still want to get data if the cluster is down so I'll consider it as last option.
The docker API wizard gave great value to out team, that's why a kubernetes one would make the process of adding a cluster much more helpful and comprehensive.
I guess it's a long shot but is there a NagiosXI kubernetes operator in the making?

Best Regards,
Noam.

HI noamyi,

Thanks for the details. It is possible to set up some of those same VM status checks using SNMP, and there's a wizard built into XI for this, Linux SNMP Wizard.

A final decision has not been made on new wizards for XI 6, my recommendation would be to take a look at some of the community plugins available for kubernetes, for example:

kubernetes-nagios

This is a collection of bash scripts for kubernetes status checks using either the API or kubectl. Let me know if this would work for your environment.
