quotaDimensions property
The dimensions of the violated quota. Every non-global quota is enforced on a set of dimensions. While quota metric defines what to count, the dimensions specify for what aspects the counter should be increased.
For example, the quota "CPUs per region per VM family" enforces a limit on the metric "compute.googleapis.com/cpus_per_vm_family" on dimensions "region" and "vm_family". And if the violation occurred in region "us-central1" and for VM family "n1", the quota_dimensions would be,
{ "region": "us-central1", "vm_family": "n1", }
When a quota is enforced globally, the quota_dimensions would always be empty.
Implementation
final Map<String, String> quotaDimensions;
