layout: page title: Web UI and REST API


Samza's ApplicationMaster comes with a dashboard to show useful information such as:

  1. Where containers are located.
  2. Links to logs.
  3. The Samza job's configuration.
  4. Container failure count.

You can find this dashboard by going to your YARN grid's ResourceManager page (usually something like http://localhost:8088/cluster), and clicking on the “ApplicationMaster” link of a running Samza job.


REST API produces JSON and provides information about metrics, task context, config, containers and status.
