Getting VSAN diskgroup uuid

I am working on getting vsan performance information and I can query disk-group info for all disk groups. It returns perf data by uuid. However, the configuration data does not have this uuid anywhere. I am unable to match up performance data to the appropriate disk mapping object.

disk_groups = host.config.vsanHostConfig.storageInfo.diskMapping

vs

endTime = datetime.utcnow() startTime = endTime + timedelta(minutes=-10) query_spec = vim.cluster.VsanPerfQuerySpec( entityRefId='disk-group:*', labels=['iopsRcRead'], startTime=startTime, endTime=endTime ) perf_result = vsan_perfManager_query_object.QueryVsanPerf( querySpecs=[query_spec], cluster=cluster )
