Simple Cluster-Rightsizing Dashboard - non-HCI

Overview

This simple dashboard helps you determine the number of ESXi Hosts you should add, or you potentially could remove from a vSphere (non-HCI) cluster according to the demand driven capacity calculation.

More information is available on my personal blog, see:

Installation

Download and unzip the cluster-rightsizing.zip file.

 

  1. Create two metric configurations:
    1. tkopton-Cluster-KPIs - use the content in the corresponding file
    2. tkopton-Cluster-Config - use the content in the corresponding file
  2. Import the Supermetrics (file: supermetric.json)
  3. Activate the Supermetrics in your policy or policies applied to your clusters
  4. Import the View (file: content-view.xml)
  5. Import the Dashboard (file: Dashboard.zip)
  6. Wait few collections cycles

 

Usage

  1. Select Datacenter - select vSphere Datacenter to inspect
  2. Select Cluster - shows all vSphere Clusters in selected DC, select Cluster to see further details
  3. Cluster Configuration - quick config overview, first box "Enabled" shows DRS status
  4. Capacity Remaining - remaining capacity by thy most constraint resource for the selected Cluster
  5. Cluster KPIs - quick overview of current Cluster performance

 

Known Issues

  • -1 color coding not working
  • DRS Enabled Box - wrong label
  • Avg Mem Contention - no metric
  • The view shows all clusters - also the HCI ones
