Log Management

logs <app>           # display recent log output

Usage

Application Logs

You can easily get logs of an application using the logs command:

dokku logs node-js-app

Behavioral modifiers

Dokku also supports certain command-line arguments that augment the log command's behavior.

-n, --num NUM        # the number of lines to display
-p, --ps PS          # only display logs from the given process
-t, --tail           # continually stream logs
-q, --quiet          # display raw logs without colors, time and names

You can use these modifiers as follows:

dokku logs node-js-app -t -p web

will show logs continually from the web process.
