# NServiceBus Version 6 ServiceControl Plugins Upgrade Version 1 to 2



## Connecting to ServiceControl

Version 2 of the ServiceControl plugins changes the way that the plugins connect to ServiceControl. The plugins no longer derive a ServiceControl queue name from the Error/Audit queues. Additional configuration is required to specify the location of the ServiceControl queue.


### Configuration File

The location of the ServiceControl queue can be specified once for all plugins in via an `appSetting` in the endpoint configuration file.

```xml
<appSettings>
  <add key="ServiceControl/Queue"
       value="particular.servicecontrol@machine" />
</appSettings>
```


### Code

The location of the ServiceControl queue can be specified via plugin-specific extensions to the endpoint configuration.


#### Heartbeats

```csharp
var endpointConfiguration = new EndpointConfiguration("myendpoint");
endpointConfiguration.HeartbeatPlugin(
    serviceControlQueue: "ServiceControl_Queue");
```


#### CustomChecks

```csharp
var endpointConfiguration = new EndpointConfiguration("myendpoint");
endpointConfiguration.CustomCheckPlugin(
    serviceControlQueue: "ServiceControl_Queue");
```


#### SagaAudit

```csharp
var endpointConfiguration = new EndpointConfiguration("myendpoint");
endpointConfiguration.SagaPlugin(
    serviceControlQueue: "particular.servicecontrol@machine");
```
