[erlang-questions] Handling Crash Reports at scale
Tue Jun 4 13:48:04 CEST 2013
I'm not sure what you mean by defensive code, but just to be sure:
You should never let error reporting influence how you handle faults in
your software. Defensive code is a code smell in Erlang.
What you coucld do is to have a error logger handler that matches
certain often occuring errors and ignores it. Even better it should
count them (the count of something unineresting is often interesting).
For counting and other metrics you might want to have a look at folsom
