vCenter API description about instance for virtual disk performance counter "totalReadLatency"

mahe90 — Wed, 24 Feb 2016 09:06:43 GMT

We are invoking queryPerf method (vCenter API) and trying to get virtual disk performance parameter "totalReadLatency". In queryPerf output, we are getting "scsi0:0" and "scsi0:1" as instance for totalReadLatency performance counter. Can you please add more information about instance for virtual disk counters?

By instance I am referring to - https://www.vmware.com/support/developer/vc-sdk/visdk41pubs/ApiReference/vim.PerformanceManager.MetricId.html#instance

We are not able to identify "scsi0:0" is referring to which virtual disk. From DataObject - VirtualHardware, we are getting virtual disk key as 2000 and 2001. Is there any relation between scsi0:0 and 2000?

We are also getting unitNumber on VirtualHardware as 0 and 1. Does it resemble anything out of scsci0:0 and scsi0:1?

Please provide more information about instance or let us know if we are looking at wrong parameters
