To show the latency, throughput and VM write IOPS charts for in-progress snapshot consolidations you need to enable instance metrics. Without these 3 being enabled these metrics won't be collected.

Environment

Resolution

Steps to Enable Host Latency & Throughput and VM Write IOPS

 

1. Navigate to Infrastructure Operations à Configurations
2. Click on the Policy Definition tile under Policies section

For Host System & Virtual Machine ensure that the following metrics are Activated

Host System	Datastore	Total Latency (ms)	Activated	Activated
Host System	Datastore	Total Throughput (KBps)	Activated	Activated
Virtual Machine	Datastore	Write IOPS	Activated	Activated

Note that both State and Instanced State should be Activated.

For example, to Activate the Instanced State for Host System à Datastore à Total Throughput

4. Navigate to Infrastructure Operations à Configurations à Policy Definitions tile
