Comment 1 for bug 1875961

In the octavia-worker.log:

Quota exceeded message for RAM:

|__Flow 'octavia-create-loadbalancer-flow': octavia.common.exceptions.ComputeBuildException: Failed to build compute instance due to: Quota exceeded for ram: Requested 4096, but already used 49152 of 51200 ram (HTTP 403) (Request-ID: req-xyz)

Quota Exhaustion for vCPU and Instances:

                                         |__Flow 'octavia-create-loadbalancer-flow': octavia.common.exceptions.ComputeBuildException: Failed to build compute instance due to: Quota exceeded for cores, instances: Requested 2, 1, but already used 20, 10 of 20, 10 cores, instances (HTTP 403) (Request-ID: req-55ed3f13-03ad-4312-8d19-7cf087afcc05)

Searching for "Quota exceeded for (.*):" and reporting the (.*) quota buckets in the check would be quite useful.

Searching for "No more IP addresses available on network (.*)\." and reporting the matching network ID that has IP exhaustion would be helpful for the operator.
