A customer of mine queried the details of a metric available in vROPs “IsGreenForPlacement”
You can find this by selecting a cluster in vROPs, go to All Metrics, and just search placement.
The customer uses this metric to give a signal (Green/Red Button on a vROPs Dashboard) if a vSphere cluster can be used for on-going deployments.
Unfortunately there’s not much documented information publicly. And we ran into an issue where the metric stayed positive (yes you can deploy), but the Storage datastore had run out of space. So I went off to dig out what this metric actually does.
IsGreenForPlacement – details
After speaking to the internal teams on vROPs I found the answer;
“Regarding IsGreenForPlacement metric, only CPU and Memory participates on calculation of this metric, by default if CPU and MEM workload is less than 80% it is green.”
So storage is not taken into account.
