Correlator Management

The Apama REST API provides URIs to use with the GET method in order to return information about running Apama correlators. This information includes data such as the number of listeners, monitors, and contexts in the correlator, the number and types of events, and the number of Java applications. For details about the type of information returned by these methods, see Watching correlator runtime status and Inspecting correlator state.
