A Wild History State Appears! - Http Login Notifying

I saw a new state pop up last night, I was wondering where it came from (or how to discover where it came from):

I was wondering if it could be related to some icinga2 health checks that I added last night, but not really sure how.

I just got the same entry this morning.
Did you ever figured it out?

I never did @ardovini.

This might help.
