logstash is a tool for managing events and logs. You can use it to collect logs, parse them, and store them for later use (like, for searching). Speaking of searching, logstash comes with a web interface for searching and drilling into all of your logs.
It is fully free and fully open source. The license is Apache 2.0, meaning you are pretty much free to use it however you want in whatever way.
For more info, see http://logstash.net/
Need help? Try #logstash on freenode irc or the email@example.com mailing list.
You can also find documentation on the http://logstash.net site.
If you don't have JRuby already (or don't use rvm, rbenv, etc), you can have
bin/logstash fetch it for you by setting
USE_JRUBY=1 bin/logstash ...
Otherwise, here's how to get started with rvm:
# Install JRuby with rvm rvm install jruby-1.7.8 rvm use jruby-1.7.8
Now install dependencies:
# Install logstash ruby dependencies bin/logstash deps
# to use logstash gems or libraries in irb, use the following # this gets you an 'irb' shell with logstash's environment bin/logstash irb # or use irb from the jar java -jar logstash-<version>-monolithic.jar irb # Run logstash bin/logstash agent [options] # If running bin/logstash agent yields complaints about log4j/other things # This will download the elasticsearch jars so logstash can use them. make vendor-elasticsearch
There are a few ways to run the tests. For development, using
bin/logstash rspec <some spec> will suffice:
% bin/logstash rspec spec/filters/grok.rb ................... Finished in 0.123 seconds 19 examples, 0 failures
Alternately, if you have just built the flatjar, you can run the tests specifically on those like so:
If you want to run all the tests from source (not compiled jar), do:
Finally, like 'bin/logstash rspec' above, you can invoke the jar to run a specific test like so:
% java -jar logstash.jar rspec spec/filters/grok.rb ................... Finished in 0.346 seconds 19 examples, 0 failures
Building is not required. You are highly recommended to download the releases we provide from the logstash site!
If you want to build the jar yourself, run:
To update a flat jar previously built with 'make flatjar', run:
You can build rpms and debs, if you need those. Building rpms requires you have fpm, then do this:
- Community: If a newbie has a bad time, it's a bug.
- Software: Make it work, then make it right, then make it fast.
- Technology: If it doesn't do a thing today, we can make it do it tomorrow.
All contributions are welcome: ideas, patches, documentation, bug reports, complaints, and even something you drew up on a napkin.
Programming is not a required skill. Whatever you've seen about open source and maintainers or community members saying "send patches or die" - you will not see that here.
It is more important to me that you are able to contribute.
For more information about contributing, see the CONTRIBUTING file.
