The purpose of this document is to give you the best practices for supervising your Nutanix Cluster in order to produce a service weather representative of its condition.

Pre-requisites

The use of our Nutanix service models requires the following prerequisites:

  • A read-only Nutanix Prism connection account used to query the Nutanix API
  • SNMPv2 or SNMPv3 configuration information

Nutanix Architecture, Concepts and Components

Your Nutanix cluster closely integrates processing, storage, network and virtualization components.

The Nutanix virtual computing platform is a convergent and scalable computing and storage system specially designed to host and store virtual machines.

All nodes in a Nutanix cluster converge to provide a unified pool of tiered storage and present resources to virtual machines for transparent access. A global data system architecture integrates each new node in the cluster, allowing you to scale the solution to meet the needs of your infrastructure.

The base unit for the cluster is a Nutanix node. Each cluster node runs a standard hypervisor and contains processors, memory and local storage (SSDs and hard disks).

A Nutanix Controller virtual machine runs on each node, allowing the local storage of all nodes in the cluster to be shared.

Configuration

Supervision of each of the components of the Nutanix architecture

Supervision of the Nutanix Cluster

Monitor the status and performance of your Nutanix Cluster by adding service models to measure its performance:

  • Nutanix-Cluster-Status
  • Nutanix-Cluster-IOPS
  • Nutanix-Cluster-Latency
  • Nutanix-Cluster-IOBandwidth

Monitoring the capacity and performance of Nutanix Cluster Storage

Supervise the general use of Nutanix Cluster Storage by using service models to measure its general use:

  • Nutanix-Cluster-StorageUsage

A Nutanix Cluster Storage cluster is made up of Containers grouping together one or more Storage Pools. In the event of an alert on the Nutanix-Cluster-Storage Usage, you will quickly be able to find out the cause by also supervising the Containers and Storage Pools using the following service models:

  • Nutanix-Container-Usage
  • Nutanix-Storage Pool-Usage

Supervision of the Nutanix Blocks making up the Cluster

Ensure the good health of your Nutanix Blocks by using the following service models:

  • Nutanix-Disk-Status

Supervision of the Supervisors of each Nutanix Node

Also make sure that the hypervisors in each of the hospitals are in good health. Nutanix Node.

When using VMware technology, you can use the following service models to monitor the health of your ESXs:

  • VMware-ESX-CPU
  • VMware-ESX-Datastore
  • VMware-ESX-DiskIO-Read
  • VMware-ESX-DiskIO-Write
  • VMware-ESX-Hardware
  • VMware-ESX-NetUsage
  • VMware-ESX-RAM
  • VMware-ESX-Runtime_Issues
  • VMware-ESX-Runtime_status
  • VMware-ESX-Services
  • VMware-ESX-Services-WithExclusion
  • VMware-ESX-SWAP

Model your Nutanix Cluster with the ServiceNav supervision tool.

Once the supervision is done, you will be able to model your Service Weather.

ServiceNav's "Service Weather" feature allows you to graphically model your Nutanix Cluster.

Through your weather services that you have configured following our recommendations and best practices available hereIf you have a Nutanix Cluster, you will be able to schematize the different components of your Nutanix Cluster identically:

The capture below is an example, we find the different elements constituting a Nutanix Cluster including :

As shown in the capture below, the interest of such a model is to be able, in case of an alert, to directly access the "root cause" or root causes of a degradation of the Nutanix Cluster. The capture below clearly shows that this degradation is due to a Critical alert from the Container 1 Usage 1 Pool

You are able to mobilize the competent teams to intervene on your Nutanix Storage and increase your chances of resolving the problem for a quick return to normal.

Reproduce your weather from Nutanix services through our cartographic dashboard module by following our available best practices. here
