Beschreibung

The following 4 metric dimensions are returned in the list metric definition call - _https://docs.microsoft.com/en-us/rest/api/monitor/metricdefinitions/list_
with
resourceUri = _/subscriptions/1248268d-051f-432a-8e63-e83a9d36e776/resourceGroups/aks-int-resource-group/providers/Microsoft.ContainerService/managedClusters/aks-int-cluster/_

But, the metrics list call doesn’t seem to return any timeseries values when queried with all the above dimensions:
REST call -
_https://docs.microsoft.com/en-us/rest/api/monitor/metrics/list_
with
**resourceUri** = _/subscriptions/1248268d-051f-432a-8e63-e83a9d36e776/resourceGroups/aks-int-resource-group/providers/Microsoft.ContainerService/managedClusters/aks-int-cluster/_
**metricnames**=_kube_node_status_condition_
**aggregation**=_Total,Average,Minimum,Maximum,Count_
**$filter**=_condition eq '*' and node eq '*' and status eq '*' and status2 eq '*'_

The issue seems to be with dimensions **status** and **status2**

Azure doesn’t return anything when filtered with **$filter=status eq '\*' and status2 eq '\*'**
We expect this should return all time series with metadata **status** and **status2**

Also the dimension **status2** is not listed in _https://docs.microsoft.com/en-us/azure/monitoring-and-diagnostics/monitoring-supported-metrics_ , but is being returned in the REST API Call.

We need help to understand if **status** and **status2** are valid dimensions? If yes, is there a way we can get the time series data when filtered on these dimensions?

Let us know if more details are needed to investigate this. This is little critical for us, so any help is appreciated. Thanks.

Rechercherichtung

Start with the Azure Monitor metric definitions/list and metrics/list REST endpoints cited in the issue, using the kube_node_status_condition resource and its condition, node, status, and status2 filters. Compare the returned dimensions and time series behavior, then document whether status and status2 are valid and what response or supported query would constitute a resolution.
