--- title: Azure Event Hub description: Azure Event Hub is a large scale data stream managed service breadcrumbs: Docs > Integrations > Azure Event Hub --- # Azure Event Hub ## Overview{% #overview %} Azure Event Hub is a large scale data stream managed service. Get metrics from Azure Event Hub to: - Visualize the performance of your Event Hubs. - Correlate the performance of your Event Hubs with your applications. ## Setup{% #setup %} ### Installation{% #installation %} If you haven't already, set up the [Microsoft Azure integration](https://docs.datadoghq.com/integrations/azure.md) first. There are no other installation steps needed. ### Metric collection{% #metric-collection %} In the [Azure integration tile](https://docs.datadoghq.com/integrations/azure.md), ensure that `Event Hub` is checked under metric collection. ### Log collection{% #log-collection %} To collect logs from Event Hubs follow this general process: - Create an Azure Event Hub from the Azure portal, the Azure CLI, or Powershell. - Setup the Datadog-Azure Function which forwards logs from your event hub to Datadog. - Forward your Event Hubs logs to the newly created Event Hub. For detailed instructions follow the main [Azure log documentation](https://docs.datadoghq.com/integrations/azure.md#log-collection). ## Data Collected{% #data-collected %} ### Metrics{% #metrics %} | | | | | **azure.eventhub\_namespaces.active\_connections**(count) | Total Active Connections for Microsoft.EventHub.*Shown as connection* | | **azure.eventhub\_namespaces.archive\_backlog\_messages**(count) | Event Hub archive messages in backlog for a namespace (Deprecated)*Shown as message* | | **azure.eventhub\_namespaces.archive\_message\_throughput**(rate) | Event Hub archived message throughput in a namespace (Deprecated)*Shown as byte* | | **azure.eventhub\_namespaces.archive\_messages**(count) | Event Hub archived messages in a namespace (Deprecated)*Shown as message* | | **azure.eventhub\_namespaces.capture\_backlog.**(count) | Capture Backlog for Microsoft.EventHub. | | **azure.eventhub\_namespaces.captured\_bytes.**(gauge) | Captured Bytes for Microsoft.EventHub.*Shown as byte* | | **azure.eventhub\_namespaces.captured\_messages.**(count) | Captured Messages for Microsoft.EventHub.*Shown as message* | | **azure.eventhub\_namespaces.connections\_closed.**(count) | Connections Closed for Microsoft.EventHub.*Shown as connection* | | **azure.eventhub\_namespaces.connections\_opened.**(count) | Connections Opened for Microsoft.EventHub.*Shown as connection* | | **azure.eventhub\_namespaces.failed\_requests**(count) | Total failed requests for a namespace (Deprecated)*Shown as request* | | **azure.eventhub\_namespaces.incoming\_bytes\_deprecated**(gauge) | Event Hub incoming message throughput for a namespace (Deprecated)*Shown as byte* | | **azure.eventhub\_namespaces.incoming\_bytes\_per\_sec**(gauge) | Incoming Bytes per second for Microsoft.EventHub.*Shown as byte* | | **azure.eventhub\_namespaces.incoming\_bytes.**(gauge) | Incoming Bytes for Microsoft.EventHub.*Shown as byte* | | **azure.eventhub\_namespaces.incoming\_messages**(count) | Incoming Messages for Microsoft.EventHub.*Shown as message* | | **azure.eventhub\_namespaces.incoming\_messages\_deprecated**(count) | Total incoming messages for a namespace (Deprecated)*Shown as message* | | **azure.eventhub\_namespaces.incoming\_messages\_count**(count) | Total incoming messages for a namespace.
