How to avoid TCPIngress keep ping tcp endpoints or reduce logs/rate?

[sheltonsuen]

We config a TCPIngress to proxy connections from iot devices to iot services, the functionality is ok, and we can have correct connection between devices and services,

But the console keep print logs as below, something like the IngressController keep trying to ping the iot service:
