Metrics

The following list contains the core metrics reported by Arm® MAP.

Only available metrics are exported to JSON. For example, if there is no Lustre filesystem then the Lustre metrics will not be included. If any custom metrics are loaded, they will be included in the JSON, but are not documented here.

For more information on the metrics, see Metrics view
