Description Dan Mace 2020-06-05 12:41:11 UTC
Description of problem:

The etcd-operator continuously logs connection messages like

I0604 15:21:55.493469       1 endpoint.go:68] ccResolverWrapper: sending new addresses to cc: [{https://10.0.0.4:2379  <nil> 0 <nil>}]
I0604 15:21:55.496008       1 controlbuf.go:508] transport: loopyWriter.run returning. connection error: desc = "transport is closing"
I0604 15:21:55.496107       1 controlbuf.go:508] transport: loopyWriter.run returning. connection error: desc = "transport is closing"
I0604 15:21:55.499193       1 client.go:360] parsed scheme: "endpoint"

These messages are not indicative of any problem we care about, and are also associated with internal gRPC client metrics we could extract if we wanted to know about them. As it stands, the messages fill up the logs and cause confusion and should be suppressed.

Version-Release number of selected component (if applicable):

4.4+

How reproducible:

Launch a new cluster, look at etcd-operator logs.

Actual results:

Log spam as described.

Expected results:

Blissful silence in the steady state.
