Class Attribute Details

.client ⇒ Object

The client object is responsible for delivering formatted data to the Sentry server.

# File 'lib/raven/base.rb', line 48

def client
  @client ||= Client.new(configuration)
end

.configuration ⇒ Object

The configuration object.

Class Method Details

.annotate_exception(exc, options = {}) ⇒ Object Also known as: annotateException, annotate

Provides extra context to the exception prior to it being handled by Raven. An exception can have multiple annotations, which are merged together.

The options (annotation) is treated the same as the “options“ parameter to “capture_exception“ or “Event.from_exception“, and can contain the same “:user“, “:tags“, etc. options as these methods.

These will be merged with the “options“ parameter to “Event.from_exception“ at the top of execution.

Examples:

begin
  raise "Hello"
rescue => exc
  Raven.annotate_exception(exc, :user => { 'id' => 1,
                           'email' => '[email protected]' })
end

def annotate_exception(exc, options = {})
  notes = exc.instance_variable_get(:@__raven_context) || {}
  notes.merge!(options)
  exc.instance_variable_set(:@__raven_context, notes)
  exc
end

.capture(options = {}) ⇒ Object

Capture and process any exceptions from the given block, or globally if no block is given

Examples:

Raven.capture do
  MyApp.run
end

  begin
    yield
  rescue Error
    raise # Don't capture Raven errors
  rescue Exception => e
    capture_exception(e, options)
    raise
  end

  if (evt = Event.send("from_" + message_or_exc, obj, options))
    yield evt if block_given?
    if configuration.async?
      configuration.async.call(evt)
    else
      send(evt)
    end
  end
end

.configure {|configuration| ... } ⇒ Object

Call this method to modify defaults in your initializers.

Examples:

Raven.configure do |config|
  config.server = 'http://...'
end

end

.extra_context(options = {}) ⇒ Object

Extra context shows up as Additional Data within Sentry, and is completely arbitrary.

Examples:

Raven.extra_context('my_custom_data' => 'value')


182
183

  available_integrations = %w[delayed_job rails sidekiq rack rake]
  integrations_to_load = available_integrations & Gem.loaded_specs.keys
  # TODO(dcramer): integrations should have some additional checks baked-in
  # or we should break them out into their own repos. Specifically both the
  # rails and delayed_job checks are not always valid (i.e. Rails 2.3) and
  # https://github.com/getsentry/raven-ruby/issues/180
  integrations_to_load.each do |integration|
    begin
      require "raven/integrations/#{integration}"
    rescue Exception => error
      self.logger.warn "Unable to load raven/integrations/#{integration}: #{error}"
    end

    logger.info "Raven #{VERSION} ready to catch errors"
  else
    logger.info "Raven #{VERSION} configured not to send errors."
  end
end

.send(evt) ⇒ Object

Send an event to the configured Sentry server
