ruby on rails - How to save Heroku logs to text file

Question

I am having a problem with logs in Heroku. When I want to look at the logs, sometimes I have missed a few lines. How can I save Heroku server logs to file.txt, or any other file?

Answer 1

You can try this:

heroku logs -n number_of_lines --app application_name >> file_name

>> operator will appends the command output to the end of a file : file_name

however, heroku keeps the last 1,500 lines of consolidated logs. If you’d like to persist more than 1,500 lines for long-term storage, search, alerting, filtering and other processing, you can use logging Add-on Providers.
