Example
Heroku aggregates three categories of logs for your app:
-
App logs - Output from your application. This will include logs generated from within your application, application server and libraries. (Filter:
--source app) -
System logs - Messages about actions taken by the Heroku platform infrastructure on behalf of your app, such as: restarting a crashed process, sleeping or waking a web dyno, or serving an error page due to a problem in your app. (Filter:
--source heroku) -
API logs - Messages about administrative actions taken by you and other developers working on your app, such as: deploying new code, scaling the process formation, or toggling maintenance mode. (Filter:
--source heroku --dyno api)
