現象

Desired metrics called:
  • "UsedUsableCapTB"
  • "UsableCapacityTB"
  • "SubscribedCapacityTB"
  • "OverallCompressionRatio"
  • "SnapModifiedCapTB"
  • "SubscribedAllocatedCapTB"


SMAS logs:
ERROR [em.bp.RESTAPI] (default task-486) RestapiExceptionMapper.toResponse(): Error: : com.emc.em.restapi.exception.RestapiException: No supported metrics passed for current System version
.

原因

These particular metrics are no longer available in V4 PowerMax arrays.

解決方法

Using URL's will provide available metrics for the array called. The SID would be the V4 array.
(SID=complete serial number with 3 leading zeros, no HK000, BR000, or CK000. Ex 000123456789)

その他の情報

The same KPI's (metrics) are seen in Unisphere for PowerMax performance charts. In general, there are default KPI's available to draw performance charts with and some that might need to be enabled in "Settings/Performance/Metrics." Depending on the array model, some are not available here as well because the metrics does not exist. In the case of the V4 PowerMax 2500/8500's.
