Unisphere for VMAX rest API : some performance metrics in the request body cause the request to fail

Unisphere for VMAX rest API : some performance metrics in the request body cause the request to fail.

Unisphere version 8.0.1.12

Following is an example (sensitive information replaced with 'xxxx'). When querying Disk metrics, I am requesting (between other things) "DiskReads".

The response contains an error message about DiskReads not being valid or something like it. I haven't tried but if I remove DiskReads from the query, I am almost sure I'll have the same problem with DiskWrites. Generally speaking, I have the same problem on many performance metrics, on other objects.

Any idea what's going on?

Thanks,

Laurent.

Looks like the answer is in the release notes (in the known issues):

The following performance metrics are not supported with the REST API:

Disk Metrics:

  DiskReads

  DiskWrites

  SeekDistance

Disk Group Metrics:

  DiskReads

  DiskWrites
