Push metrics to the MID Server You can use REST messages to send metric information to the Operational Intelligence MID Server. This method is based on client-side tools that push the raw data from the external source to the MID Server. The ITOA MetricExtension extension is required to be configured with the Enable REST Listener option enabled. For more information on setting up the MID Server, see Get started with Operational Intelligence. For information on authentication requirements, see Configure the MID Web Server extension.
