I'm trying to get my logz.io set up and running and during that process I'm noticing that my ingress controller pod is spitting out a lot of logs. I don't know if its normal or not, but I see a TON of entries in the logs that look like this
[06/Sep/2019:21:27:14 +0000]TCP200004.999
[06/Sep/2019:21:27:17 +0000]TCP200005.000
[06/Sep/2019:21:27:19 +0000]TCP200005.001
[06/Sep/2019:21:27:22 +0000]TCP200004.999
[06/Sep/2019:21:27:24 +0000]TCP200005.001
[06/Sep/2019:21:27:27 +0000]TCP200005.000

Is this normal? Is my ingress configured wrong? I don't want to see thousands of these entries in my logz.io instance.
Usually, these logs records reflect TCP/UDP services configuration for upstream backends, when Nginx Ingress controller applies proxy stream for TCP/UDP connections from relevant ConfigMap by adding specific lua block to the nested Nginx ingress controller Pod.
