 ### ResourceTags handling
 
-Tag can be dynamically added to metrics and processed though filters
-
-format is: `tagname?filter1` or `tagname?filter1&filter2`
-
-| Tag filter | Description                 |
-|------------|-----------------------------|
-| `toLower`  | Lowercasing Azure tag value |
-| `toUpper`  | Uppercasing Azure tag value |

 ### AzureTracing metrics
 
-(with 22.2.0 and later)
-
-Azuretracing metrics collects latency and latency from azure-sdk-for-go and creates metrics and is controllable using
-environment variables (eg. setting buckets, disabling metrics or disable autoreset).
-
-| Metric                                   | Description                                                                            |
-|------------------------------------------|----------------------------------------------------------------------------------------|
-| `azurerm_api_ratelimit`                  | Azure ratelimit metrics (only on /metrics, resets after query due to limited validity) |
-| `azurerm_api_request_*`                  | Azure request count and latency as histogram                                           |

-| `METRIC_AZURERM_API_REQUEST_BUCKETS`     | `1, 2.5, 5, 10, 30, 60, 90, 120`   | Sets buckets for `azurerm_api_request` histogram metric        |
