has_handler?
Determins if exception
has a registered handler via rescue_from
# File lib/oboe/frameworks/rails/inst/action_controller.rb, line 19 def has_handler?(exception) # Don't log exceptions if they have a rescue handler set has_handler = false rescue_handlers.detect { | klass_name, handler | # Rescue handlers can be specified as strings or constant names klass = self.class.const_get(klass_name) rescue nil klass ||= klass_name.constantize rescue nil has_handler = exception.is_a?(klass) if klass } has_handler rescue => e Oboe.logger.debug "[oboe/debug] Error searching Rails handlers: #{e.message}" return false end
log_rails_error?(exception)

log_rails_error?
Determins whether we should log a raised exception to the TraceView dashboard. This is determined by whether the exception has a rescue handler setup and the value of Oboe::Config
# File lib/oboe/frameworks/rails/inst/action_controller.rb, line 42 def log_rails_error?(exception) # As it's perculating up through the layers... make sure that # we only report it once. return false if exception.instance_variable_get(:@oboe_logged) has_handler = has_handler?(exception) if !has_handler || (has_handler && Oboe::Config[:report_rescued_errors]) return true end false end

Our render wrapper that just times and conditionally reports raised exceptions
# File lib/oboe/frameworks/rails/inst/action_controller.rb, line 61 def render_with_oboe(*args, &blk) Oboe::API.log_entry('actionview') render_without_oboe(*args, &blk) rescue Exception => e Oboe::API.log_exception(nil, e) if log_rails_error?(e) raise ensure Oboe::API.log_exit('actionview') end
