Description

Reported by @Tgr on irc. Fatal errors are showing up in /a/mw-log/fatal.log on fluorine that can't be found in the Logstash managed data using Kibana.

Example fatal.log entry:

exception.log entries also do not appear in logstash. Some errors appeared in neither places (I checked fatal.log, exception.log and hhvm.log) - the one I remember was a class not found error (I had to retrace the steps in the code in eval.php to find out what's wrong).
