Overview

Invoke with:

scout_agent upload_log [FILE_DATE]

This command can help us troubleshoot problems with your agent. You can invoke this to pass a log file up to our servers, so we can look through it for problems. Note that this is never done automatically. You must invoke this command manually.

The FILE_DATE is just the date of the log file in the form YYYY-MM-DD.
