Sentry-ruby: Capture backtrace on Raven.capture_message

[sobrinho]

Hey,

I'm trying to use raven-ruby to capture rails deprecation warnings but I'm not finding a way to pass the backtrace to sentry.

My current approach:

ActiveSupport::Notifications.subscribe('deprecation.rails') do |name, start, finish, id, payload|
  Raven.capture_message(
    "DEPRECATION WARNING: #{payload[:message]}",
    :level => :warning
  )
end

Rails provides the payload[:callstack] which is the backtrace of the deprecation.

Just the message won't be really useful since I will not be able to trace from where it was triggered.

Suggestions?

I haven't tried it myself yet but check out this recent article: http://beforeitwasround.com/2014/02/sending-rails-deprecation-warnings-to-sentry.html

I'll give it a try, thanks!

I'm looking to do a similar thing and that shared link is currently dead for me. Has anyone been able to do this successfully?

Also looking to do something similar.

In case anyone stumbles upon this, one way to do it is to add the 'backtrace' option like:

rescue => e
  Raven.capture_message("Something happened", :backtrace => e.backtrace)

Closing in favor of #766.

@sobrinho - This doesn't seem related to #766 ... they're different things, right? Capturing the backtrace for messages (this issue) isn't the same as capturing the request body. Having an option to capture backtrace would still be nice - even though you can kind of do it with capture_message("message", extra: {backtrace: caller})

It seems we already have backtrace option.

https://github.com/getsentry/raven-ruby/blob/69e0d4bc216d14d7418a3a35e24a00210abeca19/lib/raven/event.rb#L71

So Raven.capture_message("message", backtrace: caller) will work

Oh wow, does that work? That's awesome...
Sure would be nice if that were documented somewhere! Maybe here, for instance: https://docs.sentry.io/platforms/ruby/usage/#optional-attributes

[mtsmfm]

Documentation PR already exists https://github.com/getsentry/sentry-docs/pull/766
It's 1 year old PR though

Oooh! This makes so much more sense! @sobrinho's closing comment above linked to the wrong # 766 😆 Okay, yup - that's awesome - hopefully someone can merge it...

[mltsy]

Fixed! :)
