 ## Analyze metrics
 You can analyze metrics for Azure Event Hubs, along with metrics from other Azure services, by selecting **Metrics** from the **Azure Monitor** section on the home page for your Event Hubs namespace. See [Analyze metrics with Azure Monitor metrics explorer](../azure-monitor/essentials/analyze-metrics.md) for details on using this tool. For a list of the platform metrics collected, see [Monitoring Azure Event Hubs data reference metrics](monitor-event-hubs-reference.md#metrics).

 ### Filter and split
 For metrics that support dimensions, you can apply filters using a dimension value. For example, add a filter with `EntityName` set to the name of an event hub. You can also split a metric by dimension to visualize how different segments of the metric compare with each other. For more information of filtering and splitting, see [Advanced features of Azure Monitor](../azure-monitor/essentials/metrics-charts.md).

 ## Analyze logs
 Using Azure Monitor Log Analytics requires you to create a diagnostic configuration and enable __Send information to Log Analytics__. For more information, see the [Collection and routing](#collection-and-routing) section. Data in Azure Monitor Logs is stored in tables, with each table having its own set of unique properties. Azure Event Hubs stores data in the following tables: **AzureDiagnostics** and **AzureMetrics**.
