Report is intermittently missing data and shows only dashes (-) in reports defined against multiple object types

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

• A report defined against multiple object types (i.e hosts and VMs) sometimes works fine and sometimes shows only a dash/hyphen (-) for some metrics
• The metric defined in the report is collected regularly
• A metric defined in the report has a common metric name for multiple objects (i.e. Memory | Usage % which is a valid metric for both hosts and VMs)

Environment

VMware Aria Operations 8.x

Cause

There is a known issue with Aria Operations 8.x causing this behavior that will be fixed in a future version.

Resolution

To work around the issue,

• The objects can be split into different views per object type
  • Example One view contains host metrics and a separate view contains VM metrics
    
    
• The transformation used for the metric in the view can be changed to use different types per object
  • Example The view containing both host and VM Memory|Usage % metrics uses the Current transformation for the host metric and the Last transformation for the VM metric
