Multiple users have reported seeing these messages in the logs when running recent (eg v1.6) releases of Cilium:

{"level":"warn","ts":"2019-12-19T17:25:29.221Z","caller":"clientv3/retry_interceptor.go:61","msg":"retrying of unary invoker failed","target":"endpoint://client-62c44804-9924-4add-a807-d58b11854d2f/etc-server1:2379","attempt":0,"error":"rpc error: code = Canceled desc = context canceled"}

Questions:

• What does this log mean?
• Does it imply broken etcd connectivity?
• What are the debugging steps?
• This log does not follow the standard Cilium log output format, can we turn it into a meaningful log or report its status through a Cilium controller?
