Listener node

The Listener node streams live data from a web or cloud source in a process known as streaming ingest. 

Streaming ingest provides the capability for Interana to accept a dynamic flow of events (data-in-motion) via an HTTP API. The Interana Listener node has the following capabilities:

  • A uwsgi server that receives HTTP posts at high volume
  • An internal messaging layer
  • A service to coordinate and maintain shared data by a group of nodes 

You can add a Listener node to a single-node cluster, or stack it with another node (such as the import node) in a multi-node cluster. If desired, you can make the Listener a separate node in the cluster.
