Awesome Logging for Rails
This is a fork of shadabahmed/logstasher. It has been updated to use the latest event schema and customized to better fit the needs of MoneyDesktop--though it is still generally useful. It is not backward compatible with its progenitor.
This gem makes it easy to generate logstash compatible logs for your rails app.
A request that looks like this in your production.log:
Started GET "/login" for 10.109.10.135 at 2013-04-30 08:59:01 -0400
Processing by SessionsController#new as HTML
Rendered sessions/new.html.haml within layouts/application (4.3ms)
Rendered shared/_javascript.html.haml (0.6ms)
Rendered shared/_flashes.html.haml (0.2ms)
Rendered shared/_header.html.haml (52.9ms)
Rendered shared/_title.html.haml (0.2ms)
Rendered shared/_footer.html.haml (0.2ms)
Completed 200 OK in 532ms (Views: 62.4ms | ActiveRecord: 0.0ms | ND API: 0.0ms)
Will look like this in your logstash_production.log:
{"tags":["request"],"method":"GET","path":"/","format":"html","controller":"file_servers"
,"action":"index","status":200,"duration":28.34,"view":25.96,"db":0.88,"ip":"127.0.0.1","route":"file_servers#index",
"parameters":"","ndapi_time":null,"uuid":"e81ecd178ed3b591099f4d489760dfb6","user":"[email protected]",
"site":"internal","@timestamp":"2013-04-30T13:00:46.354500+00:00","@version":"1"}From there, it's trivial to forward them to your logstash indexer. You can even use the included redis log device to send the logs directly to a redis broker instead.
In your Gemfile:
gem 'md-logstasher'
# Enable the logstasher logs for the current environment
config.logstasher.enabled = true
# Optionally silience the standard logging to <environment>.log
config.logstasher.silence_standard_logging = true
By default, Logstasher will add params as a JSON encoded string. To disable,
add the following to your <environment>.rb
# Disable logging of request parameters
config.logstasher.include_parameters = false
If you want the parameters to be sent unserialized, so they are indexed and searchable individually in elasticsearch, skip the serialization step.
# Log parameters individually
config.logstasher.serialize_parameters = false
Since some fields are very specific to your application, e.g., user_name, it is left upto you to add them. Here's how to do it:
# Create a file - config/initializers/logstasher.rb
if LogStasher.enabled
LogStasher.append_fields do |fields|
# This block is run within the context of the controller handling the
# request, so you have access to all its methods and instance variables
fields[:user] = current_user && current_user.mail
fields[:site] = request.path =~ /^\/api/ ? 'api' : 'user'
end
end
All versions require Rails 3.0.x and higher and Ruby 1.9.2+. Tested on Rails 4 and Ruby 2.0
