Lamian

Lamian is an in-memory logger, which content could be released for error messages. It is designed to work in pair with exception_notification gem inside rails aplications

1. Add gem 'lamian' into your Gemfile
2. Extend Rails.logger and any other loggers you want to mirror by Lamian::LoggerExtension: Lamian.extend_logger(logger)
3. Add 'request_log' section inside your ExceptionNotification.configure (see ExceptionNotification README)
4. ExceptionNotification's messages would have 'Request Log' section

Add a 'request_log' section into ExceptionNotification's background section. Add Lamian.run { } around code with logs you want to collect. Note, that logs would be accessible only inside this section and removed after section end.

It automatically redefines Sentry.configuration.before_send callback if Sentry initialization is completed. If before_send is already defined it wraps custom callback.

You should add Lamian middleware to the Sidekiq initializer like this:

config.server_middleware do |chain|
  chain.prepend(Lamian::SidekiqSentryMiddleware)
end

You should add Lamian appender to the SematicLogger appenders like this:

SemanticLogger.add_appender(appender: Lamian::SemanticLoggerAppender.new)

If you want to send events asynchronously you need to patch Sentry::Scope.

# Somewhere in a initializer.

Sentry::Scope.prepend(Lamian::SentryScopePatch)

Add this line to your Sentry initializer:

Raven::Context.prepend(Lamian::RavenContextExtension)

You should add Lamian middleware to the Sidekiq initializer like this:

config.server_middleware do |chain|
  chain.prepend(Lamian::SidekiqRavenMiddleware)
end

• It probably should be separated to lamian and lamian-rails gems. Rails dependency is never cool
