Search for a pattern in your log files

I generally use a tracking gif in the mass emails I send out to get a rough idea of the open rate. It's not a small task to open each log file, filter it and then count each occurance of the gif.

Hunter does this for you!

WARNING: Hunter has no tests. This was thrown together, so use with caution. Contributions are very welcome.

How to Use

Install

    gem install hunter

Use

Create a new hunt for the string you want to match:

    hunt = Hunter::Hunt.new('/images/email/tracking.gif')

Look in the current log

    hunt.look_in('/var/log/httpd/access.log')

Look in an archived log

    hunt.look_in_archived('/var/log/httpd/log_archive/access.log.1.gz')

Look through a folder of archived logs

    hunt.look_through_archive('/var/log/httpd/log_archive')

Look through a folder of archived logs for a specific log type

    hunt.look_through_archive('/var/log/httpd/log_archive', 'access.log')

Known Issues

• "Archived" means with the file extension .gz – no other compression formats are supported
• look_through_archive() relies on your log appending a digit after the original filename and then compressing to .gz
  • e.g. access.log becomes access.log.1.gz
• There are no tests
