# Log Emitter

There is one Log Emitter Node that is created for your Tenant when you create your Tenant.

Managed Nodes (really, the Docker containers that implement Managed Nodes) and the Processor functions and Bitmapper functions that are executed in Process and Bitmap Router Nodes, respectively, all can create log messages that are collected and stored centrally within the EchoStream Cloud.

Log messages that are created by these Nodes are emitted as `echo.log` messages in near real-time by the Log Emitter Node in your Tenant.

You may create a Node that can process `echo.log` messages and connect it to your Log Emitter. Some use cases for processing `echo.log` messages are:

- Sending the log messages to your own centralized log aggregration and analysis system (e.g. - Splunk, SumoLogic, ELK, DataDog, AWS Cloudwatch Logs).
- Processing the log messages in near real-time, searching for errors or anomolies.
