The CloudHealth agent or another data aggregation application is required for the platform to ingest memory and disk scores.
By default, CloudHealth does not pull in memory or disk metrics. In order to get these metrics ingested into the platform, the CloudHealth agent or a third party aggregator, such as Datadog, will need to be configured on your infrastructure.
For more information on the CloudHealth agent, see: https://docs.vmware.com/en/VMware-Aria-Cost/SaaS/using-and-managing-vmware-aria-cost/GUID-integrating-with-services.html#integrate-with-vmware-aria-cost-agent-6
