I was reading Jason Seifer’s: Offline Gem Server Rdocs, which is an apache/passenger served Sinatra app that allows you to view the Rdocs of installed gems without using gem server. Nice. So I installed it on our sandbox server for all to enjoy.
But it got me thinking, there is another think I like to keep an eye on on our servers… log files. Oh, and I was looking for good excuse to play around with Sinatra. So, “with a one, and-a-two, and-a-three…” we have Sinatra-Tailer.
You can read all about it on the github page, but in short it simply performs a tail and displays the last X lines of the log file.
tail -n /path/to/my/log/file.log
- refreshes the list every X seconds, set by the user
- only one config.yml file to edit
- supports file globs, so you can grab a whole list of file with one line
- specify the number of lines to show
- completely unobtrusive js, because I’m cool?
- Sinatra framework (tested on 0.9.1.1, earlier may work)
I whipped this up pretty quickly so I’m sure there are a few bugs. There is some testing for a few unit tests, but nothing functional.
One word of warning, if you want to put this on a production server my recommendation is to put it on a separate port (like 9876) and for heaven’s sake, at a minimum use http basic authentication. From the sinatra readme:
use Rack::Auth::Basic do |username, password| username == 'admin' && password == 'secret' end
