Can't find 5xx URI errors in the logs (App Eng

Question

I see 95% URI errors for a certain URI, and the absolute number grows every minute, but I still can't find the errors for this URI in the Logs tab.

Any idea how can I debug this problem?

Answer 1

If you use the log viewer in the new developer console you can filter logs by status,

e.g. status:503

It seems more reliable than the old one (and a lot more flexible).
