Recon serves as a management and monitoring console for Ozone. It’s an optional component, but it is strongly recommended to add it to the cluster since Recon can help with troubleshooting the cluster at critical times. Refer to Recon Architecture for detailed architecture overview and Recon API documentation for HTTP API reference.
Recon is a service that brings its own HTTP web server and can be started by the following command.
ozone --daemon start recon
