Description Jessica Forrester 2020-04-01 00:10:21 UTC

The aws-controller is writing the "Updated machine zzzzzzz" events out every ~10 minutes for every single machine. I do not see any actual update to the Machine object occurring. This results in about 200 unnecessary events a day per machine. We should only be writing events when we are actually persisting updates to the Machine object.

Example of one of the events:

Comment 4 Paige Rubendall 2020-05-08 19:01:17 UTC

Looking in the web console, I am able to see the updating events that were seen before for any of the machines in my cluster. I am able to see the text "No events in the past hour" for all my worker machines.
