Disk metrics are not displayed in VMware Cloud Director

Products

• VMware Cloud Director

Issue/Introduction

• Metrics collection has been successfully configured for VMware Cloud Director, as described in the following:
  
  Configure Metrics Collection and Publishing in VMware Cloud Director
  
  
• Metrics for most values are being displayed normally.
• disk.read.average and disk.write.average do not have any values.

Environment

VMware Cloud Director 10.x

Cause

Metrics collected and displayed by VMware Cloud Director are produced by the underlying vSphere environment. For some disk types, disk.read.average and disk.write.average values are not collected. For example, virtualDisk.read.average and virtualDisk.write.average data is collected for vSAN datastores instead of disk.read.average and disk.write.average. The data collected for a virtual machine can be confirmed by reviewing the performance metrics in the vCenter client.

Resolution

VMware Cloud Director can only display metrics collected by the underlying infrastructure and is behaving as expected.
