I am confused by the error as MWEventLogger seems to implement EventLogger and this code hasn't changed recently.

What I see on the linked kibana error dashboard are 2 errors, in the same second, from the same server, which was just rebooted and just started receiving traffic. It's pretty strange but I doubt there's anything more to it than some issue loading the code while the server is starting up. I even went to the actual access logs on the server, and they show how that specific server wasn't even serving live traffic at the time as it took the server 18 seconds to render the blank page - both on HHVM and php7 I might add!

So, I just guess this looks like an unfortunate event that was never served to a user.

was never served to a user.

This took me a minute to understand, but it's because the two requests that failed were from the health checker (to /wiki/Special:BlankPage?force_php7=1).

And yeah, limited to one server and PHP7, and never seen again. Let's merge for now.
