Allow Suppression of Logs from Healthcheck Endpoints

[lzettel]

Description

We have a Rails application running with the default health check implemented at /up, and we are constantly receiving logs like this:

{"time":"2025-02-11T06:48:36.879509079Z","level":"INFO","msg":"Request","path":"/up","status":200,"dur":7,"method":"GET","req_content_length":0,"req_content_type":"","resp_content_length":73,"resp_content_type":"text/html; charset=utf-8","remote_addr":"x.x.x.x:xxxx","user_agent":"kube-probe/1.28","cache":"miss","query":""}

These logs are generated by liveness probes and do not provide useful insights while adding unnecessary noise to our logs.

Rails already provides an option to silence these kinds of logs:

  # Prevent health checks from clogging up the logs.
  config.silence_healthcheck_path = '/up'

Feature Request

It would be nice to have the ability to suppress logs for specific endpoints, such as /up. The endpoint(s) could be set with an ENV.

Thanks in advance for your time and effort in considering this request!
