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.

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
