Filters Rails logs to trace user sessions for support purposes
Click the "Load Log" button and it reads in the file. Then, choose from the years, months, and days of requests in that file. Tell Ties which controller, action, and URL you are interested in.
Finally, decide if you only want to see the log entries which contain an exception, enter a regular expression to search the params, plus the output filename and click a button to filter the log entries you care to see.
Ties takes a many-megabyte Rails production log file and outputs only the entries you're interested in.
