 The connector requires no user input. The metrics that are polled for this resource type element are displayed on the **Metrics** page.
 
+### Polling Configuration
+
 Enabling or disabling polling of metrics can be done on the **Configuration** page. Polling of these metric has a direct financial impact.
 
 On the **General** page, you can configure the **Polling Interval** for the metrics. This same page also displays the scope (Subscription and Resource Group) that this resource type element belongs to.
 
+### Query Filter
+
+Also on the **General** page, you can configure the **Query Filter**. This filter is used to reduce the set of metric data returned.
+
+This is how the filter works, based on an example where the metric contains the metadata A, B, and C:
+
+- To return all time series of C where A = a1 and B = b1 or b2:
+
+  `filter=A eq 'a1' and B eq 'b1' or B eq 'b2' and C eq '*'`
+
+  Invalid variant:
+
+  `filter=A eq 'a1' and B eq 'b1' and C eq '*' or B = 'b2'`
+
+  This is invalid because the logical "or" operator cannot separate two different metadata names.
+
+- To return all time series where A = a1, B = b1 and C = c1:
+
+  `filter=A eq 'a1' and B eq 'b1' and C eq 'c1'`
+
+- To return all time series where A = a1:
+
+  `filter=A eq 'a1' and B eq '' and C eq ''`
+
+- If multiple entities are present in the same namespace, a filter can be utilized to use only one:
+
+  `filter=entityname eq 'prod'`
+
+  The following metrics support filtering by entity name:
+
+  - Abandoned Messages
+  - Active Messages
+  - Completed Messages
+  - Connections Closed
+  - Connections Opened
+  - Dead Lettered Messages
+  - Incoming Messages
+  - Incoming Requests
+  - Messages
+  - Outgoing Messages
+  - Scheduled Messages
+  - Server Errors
+  - Server Send Latency
+  - Successful Requests
+  - Throttled Requests
+  - User Errors
+
+If the specified filter does not use the correct format, or if the metric does not support a filter of that type, then the filter will not be applied.

 ## Notes
 
 This connector is intended to be used together with the **Microsoft Azure Cloud Platform** connector. Without this manager connector, the connector will not work, as the authentication to the Azure Cloud Platform is done via the manager connector.
