We are currently using "rescue_action_in_public" in application.rb to
catch exceptions and send us alert emails. However, we have recently
begun getting thousands of invalid requests with weird and very long
URLS. My guess is that it is Windows viruses that the user isn't even
aware of since they are mainly coming from Windows machines and lots of
different IP addresses. Our problem is the at it's clogging up our log
files and I think these are innocent (but annoying) enough to ignore.
What's the cleanest way to detect an invalid exception based on the URL
and not have it logged?
Not a direct answer to your question, but you may consider switching your setup to use hoptoad and then if they haven't already integrated my patch to ignore certain user agents, patch it do to so. Or just look at my patch and adjust it to fit your scenario.
No affiliation, just like their service...
