I'm currently trying to set up of several Nutanix clusters at $WORK. I'm having difficulty grasping the concepts behind Nutanix clusters while the Nutanix experts I’m talking to have a hard time understanding Centreon monitoring.

One difficulty is I have no idea what hosts I should declare in Centreon and what host templates I should attach to them. Another is that the Nutanix team is asking for data that SNMP doesn't provide (cluster memory and cpu use) and I'm at a loss to explain why their expectations and the Nutanix connector are so much at odds.

If you’ve set up Nutanix monitoring, could you give me a quick overview of how you set it up?

Are you an opensource user? If not, the templates included in the connector  are docmumented at https://docs.centreon.com/pp/integrations/plugin-packs/procedures/virtualization-nutanix-snmp/?

May be the connector lacks some important data for clusters? If so, feel free to post an Idea.


Hello,

I’m not an expert but i can try to halp

It seems there is 4 host templates for Nutanix:
- Virt-Nutanix-Container-SNMP-custom
- Virt-Nutanix-Hypervisor-SNMP-custom
- Virt-Nutanix-SNMP-custom
- Virt-Nutanix-VM-SNMP-custom

Virt-Nutanix-SNMP-custom is the Template to use if you want to monitor the Nutanix cluster global status
So you just have to create an host with this host Template, and you will have a good start


The other templates are for monitoring the specific component of your Nutanix cluster (like nodes, vm and container).

For example, if you add the Virt-Nutanix-Hypervisor-SNMP-custom template to your host, it will add a new macro named FILTERNAME

This macro is used to monitor a specific Nutanix node using it’s name. The macro want a regex, so you can put a wildcard, and the services created will monitor the CPU, Memory of all the nodes

But instead of this, you can have one host for each Nutanix node, creating one host per node, using the Virt-Nutanix-Hypervisor-SNMP-custom template

To make it easier, you can also create host discovery rules, for adding each component automatically

The Nutanix monitoring connector come with host Discovery rules to make the monitoring 

They will make SNMP requests on the Nutanix cluster to discover each component and get their metrics (like CPU or Memory)

You can create a Host Discovery rule that will create a host for each component (like nodes)


You need to specify the SNMP settings (like you did in the cluster host)


Then the rule will do it's work and list you all the components it found
Depending on the rule settings, the components can be Added manually or automatically

I hope it helps a bit
