Missing Disk Capacity Remaining Metrics

[nmanm0305]

I have a dashboard/report that shows powered-off VMs. Among other metrics for the VMs, the report shows Disk Size, Disk Free and Disk Used (a super metric calculated from the other two disk metrics) metrics.

I've noticed that most of the machines report their Disk Free amount, but some do not (screenshot below). I haven't found a reason for this, nor identified any commonality among the machines suffering from this. Any ideas?

The metric for Disk Free is Capacity Analytics Generated|Disk Space|Capacity Remaining (GB). Screenshot below

Check their VMware tools. Do they all have something in common in that respect?

VMware Tools was the culprit. Though the version running on the VMs was supported, it was not current. After upgrading Tools to current on one of the affected VMs, the Disk Free metric (Capacity Analytics Generated|Disk Space|Capacity Remaining (GB)) populated in the dashboard/report.

Thanks for the help!
