Azure Service Bus

Serverless Observability Stack APM Agent .NET

Quick start

Instrumentation can be enabled for Azure Service Bus by referencing Elastic.Apm.Azure.ServiceBus package and subscribing to diagnostic events using one of the subscribers:

If the agent is included by referencing the Elastic.Apm.NetCoreAll package, the subscribers will be automatically subscribed with the agent, and no further action is required.
If you’re using Microsoft.Azure.ServiceBus, subscribe MicrosoftAzureServiceBusDiagnosticsSubscriber with the agent
```
Agent.Subscribe(new MicrosoftAzureServiceBusDiagnosticsSubscriber());
		
```
If you’re using Azure.Messaging.ServiceBus, subscribe AzureMessagingServiceBusDiagnosticsSubscriber with the agent
```
Agent.Subscribe(new AzureMessagingServiceBusDiagnosticsSubscriber());
		
```
