If we have a Nutanix in our environment… Why don't we centralize all the information you give us in our Centreon monitoring system?? Not only to better manage alerts, but to store all its metrics and be able to work on them as we see fit, this is a post with full detail on how to fully monitor Nutanix!

What I said, This document is somewhat extensive, since we can get a lot of interesting metrics from both the Nutanix cluster and the CVMs, So we're going to separate it into different phases, first we'll look at how to enable SNMP on Nutanix and then all the options we can look at, I will give you the Command and Service that we will need for each item to be monitored. So everyone adds what is interesting, And then below I leave you how it would look!

Enabling SNMP on Nutanix,

We start! The first thing will be to enable SNMP in our Nutanix cluster to be able to obtain its metrics from our machine with Centreon,

After logging into the Nutanix administration website, We're going to “Settings” > “SNMP”,

We marked the tick of “Enable SNMP”, and in “New Transport”,

On the “Transports” we will enable the UDP protocol and port by default 161,

On the “Users” Click on “New User”,

And we assign a name to this user and the types of authentications in addition to the required passwords, As we see, Nutanix uses SNMP version 3 🙂 In this post I will use a generic user called centeron and with passwords centeron using AES and SHA, Why I'm telling you this? Why the Commands we will use will carry those credentials by default 😉

We also click on “Download MIB”, the file with the Nutanix MIBs will be required later, We keep it lying around,

Installing the requirements in Centreon,

Once we have Nutanix ready, we'll proceed to install the requirements in Centreon so that we can use a couple of scripts, to obtain certain metrics and with it we can make some of the queries that we will need, We'll download the scripts check_nutanix.pl and check_ssh_nutanix_cluster.pl, we upload the file with the newly downloaded MIBs by SCP and we are ready to install the requis:

[SourceCode]Cpan Date::Parse
cpan Net::OpenSSH
With IO::Pty
CP NUTANIX-MIB.txt /usr/share/snmp/mibs/[/SourceCode]

Eye, A note, in the script check_nutanix.pl, In the line 97, in the end, A comma is missing! And we will save it in the path of the Centreon Plugins, in /usr/lib/centreon/plugins/.

Monitoring CPU, Memory, Charging and Disk

And then, We will see what we can monitor, I'll leave you briefly, the name of the Service that I usually use, followed by the Arguments. And then at the end, the command I used. For now via SNMP,

Example of a Command,

And nothing, After all the txapa, how I have organized the Services and Commands to be created, well, I leave you an example of what a Command would look like for those who have doubts. We will have indicated the Name, the Command Line and Arguments.

Example of a Service,

And the same for each Service to be created, we will indicate the Name, we will select your Command and fill in all the Arguments you ask for.

What would it look like?

GOOD, What's interesting! This would be a snapshot of a fully controlled and monitored Nutanix environment! To the CVMs, Remember that you can add Virtual Environment Metrics and get more data on mega interesting returns! I hope you have found it useful!
