 ## Filters
 
-You can apply filters to charts whose metrics have dimensions. For example, imagine a *Transaction count* metric that has a *Response type* dimension. This dimension indicates whether the response from transactions succeeded or failed. If you filter on this dimension, you'll see a chart line for only successful or only failed transactions.

 ## Correlate metrics to logs
 
-To help customers diagnose the root cause of anomalies in their metrics chart, we created the *Drill into Logs* feature. Drill into Logs allows customers to correlate spikes in their metrics chart to logs and queries.
+**Drill into Logs** helps you diagnose the root cause of anomalies in your metrics chart. Drilling into logs allows you to correlate spikes in your metrics chart to logs and queries.

 | Term             | Definition  | 
 |------------------|-------------|
 | Activity logs    | Provides insight into the operations on each Azure resource in the subscription from the outside (the management plane) in addition to updates on Service Health events. Use the Activity log to determine the what, who, and when for any write operations (PUT, POST, DELETE) taken on the resources in your subscription. There's a single Activity log for each Azure subscription.  |
-| Diagnostic log   | Provides insight into operations that were performed within an Azure resource (the data plane), for example getting a secret from a Key Vault or making a request to a database. The content of resource logs varies by the Azure service and resource type. **Note:** Must be provided by service and enabled by customer.  |
