Memory metric type provides the metrics, properties, and tags to represent the memory performance of physical and virtual managed entities.

The VMware Telco Cloud Service Assurance collectors constructs this metric type with memory performance metrics for network devices, servers, and virtual devices. In the VMware Telco Cloud Service Assurance out-of-the box reports, this metric type is used to show the summary of memory performance trends per device and per memory instance. Leverage this metric type to create custom reports to represent memory performance using other Grafana widgets or new filters. Similarly, custom collectors can construct the metric type for the different vendor and create custom reports.
