I wanted to have a detailed look into my production.log, but heroku doesn't seem to store them. Does anyone else, have a solution for that problem. It would be nice to get it stored safely away. thanks in advance :)

The Heroku logging article shows you can read up to 1500 lines of your log file. By default, heroku logs shows the last 100 lines.

heroku logs -n 1500

Note that Heroku logging uses Logplex that merges logs from your app as well as from Heroku system. You can filter out logs produced by the system

heroku logs -n 1500 --source app

From the Heroku documentation you can see that their logging facility is limited to the last 100 lines whenever you read them back from the console.

If you have a requirement to keep and analyze all of your production logs then it looks like you will have to consider archiving them off-Heroku to, say, S3 or through EC2 logging server.

    oh, I just found it http://stackoverflow.com/questions/2671454/heroku-how-to-see-all-the-logs thanks bjg for pointing me in the right direction – tabaluga Jul 14 '10 at 11:34
  • Just for completeness you can see more than 100 lines with heroku logs --tail It's not what the OP was asking about, this is just in relation to "limited to the last 100 lines" – GreenAsJade Oct 16 '12 at 09:21

This will work in heroku, execute this from your terminal:

heroku logs -n 200

or

heroku logs -t --app <app_name> > any_file_name

Here the max -n limit is 1500
