fly logs

View application logs as generated by the application running on the Fly platform.

Logs can be filtered to a specific instance using the –instance/-i flag or to all instances running in a specific region using the –region/-r flag.

By default logs are continually streamed until the command is aborted. Use –no-tail to only fetch the logs in the buffer.
