Error Instance Configuration Settings

The configuration of a ServiceControl instance can be adjusted via the ServiceControl Management utility or by directly modifying the ServiceControl.exe.config file. The settings listed are applicable to the appSettings section of the configuration file unless otherwise specified.

The configuration of a ServiceControl Error instance is controlled by the ServiceControl.exe.config file or by setting environment variables. When a setting configuration exists as both an environment variable and in the application configuration file the environment variable setting takes precedence.

Deployments using the ServiceControl Management utility (SCMU) can use that application to make a subset of configuration settings which are read from and written to the application configuration file.

Usage Reporting when using ServiceControl

LicensingComponent/ServiceControlThroughputDataQueue

Version: 5.4.0+

The queue on which throughput data is received by the ServiceControl Error instance. This setting must match the equivalent Monitoring/ServiceControlThroughputDataQueue setting for the Monitoring instance.

In most instances these settings do not need to be modified.

If running multiple setups of the Platform Tools (i.e. multiple versions of ServiceControl error and monitoring instances) then modify these settings so that the queue on each monitoring instance is matched to the queue of its error instance.

If using MSMQ transport and the monitoring instance is installed on a different machine than the ServiceControl error instance, only the monitoring instance setting needs to be modified to include the machine name of the error instance in the queue address.
