VMware Telco Cloud Service Assurance Health Status Pod reports displays empty value for some pods. They indicate that some pods ran for sometime, consumed some CPU and Memory resources, but no longer exist.
The time picker control is hidden by default and the range of this report by default is Last 12h. The reason behind it is, narrow time window loads ElasticSearch with heavy queries.
To select a small range, you can go to the Gear icon on the top right of the reports and uncheck the option Hide time picker and go back to the reports.
