SO. MUCH. SPAM. We run as V(2).  Please either make this meaningful to an admin, remove it, or move it to a higher level.

scheduler log spam.
Comment 2 Derek Carr 2017-08-18 23:05:11 EDT
Avesh, any chance we can get a PR opened for this by 8/21 so it can make 3.6.1?

These errors are not returned as these are non-harmful errors. These errors are currently rate limited (not aggregated) in apimachinery/pkg/util/runtime/runtime.go. I think moving these to glog level 3 or beyond seems to be the only option to suppress these errors. Aggregation by returning these errors along with real errors seems hacky right now.

Aggregated across the 16 master nodes in the free and pro tiers, this log message is written over 1.2 million times in the last 24 hours (Sept 1).

Here are the top-talkers:
