Rails users: What exception notification software do you use?

Question

I have seen Ryan Bates talk about exception_logger and exception notification. Are there any other good ones to consider? What do you like and dislike about these?

Answer 1

Hoptoad is my preferred exception notifier by a landslide. It's intelligent about the emails it sends me, and it's web interface does a nice job of automatically organizing all of the exceptions.

If I make a change that causes an error, I'll likely get several of the same error messages, so Hoptoad sends me an email, and in the web interface I might see something like 4 of the same error, I can click through to the details, patch the bug, and with one click check them off as fixed.

It's a really nice clean way of handling exceptions and strikes me as far less intrusive/ghetto.
