rails application passenger possible errors

Question

I have installed splunk to retrieve information from my log files and elert me when specific keyword is found. Is there any way to get possible rails errors so that I can put those as keywords??

Answer 1

You could do this:

exceptions = []
ObjectSpace.each_object(Class) do |o| 
  exceptions << o if (o < Exception)
end

This will give you a list of all exceptions, but it will be quite large. I get 390 in pure IRB, so there will probably be closer to 5 or 600 if you've required the entire Rails.

Answer 2

You should also be able to get that by playing around with God, but I like Yehuda's answer
