Logging to Logentries in Ruby

This is a Logentries library for logging from Ruby platforms, including Heroku.

It is available on github https://github.com/logentries/le_ruby/ and rubygems http://rubygems.org/.

Example

Rails.logger.info("information message")
Rails.logger.warn("warning message")
Rails.logger.debug("debug message")

Howto

You must first register your account details with Logentries.

Once you have logged in to Logentries, create a new host with a name of your choice. Inside this host, create a new logfile, selecting Token TCP as the source type.

Heroku

To install the gem you must edit the Gemfile in your local heroku environment

Add the following line:

gem 'le'

Then from the cmd line run the following command:

bundle install

This will install the gem on your local environment.

The next step is to configure the default rails logger to use the logentries logger.

In your environment configuration file ( for production : config/environments/production.rb), add the following:

Rails.logger = Le.new('LOGENTRIES_TOKEN')

If you want to keep also the logs in the console and in the log file just add local parameter after the key:

Rails.logger = Le.new('LOGENTRIES_TOKEN', :local => true)

If you want the gem to use SSL when streaming logs to Logentries, add the ssl parameter and set it to true:

Rails.logger = Le.new('LOGENTRIES_TOKEN', :ssl => true)

If you want to print debug messages for the gem to a file called logentriesGem.log, add this:

Rails.logger = Le.new('LOGENTRIES_TOKEN', :debug => true)

You can also specify the default level of the logger by adding a :

Rails.logger = Le.new('LOGENTRIES_TOKEN', :log_level => Logger::<level>)

For the LOGENTRIES_TOKEN argument, paste the token for the logfile you created earlier in the Logentries UI.

Now, simply use Rails.logger.info("message") inside your code to send logs to Logentries
