Steps To Reproduce:

The commands below show the latest version of mongod being run for 10 seconds before being quit then having the number of lines they emitted counted. Both produce 94 lines.
```bash

callumgare@Meeka ~/r/porn-cache-new> docker run --rm --entrypoint=/usr/bin/timeout mongo:5.0.7 10 /usr/local/bin/docker-entrypoint.sh mongod | wc -l
      94
callumgare@Meeka ~/r/porn-cache-new> docker run --rm --entrypoint=/usr/bin/timeout mongo:5.0.7 10 /usr/local/bin/docker-entrypoint.sh mongod --quiet | wc -l
      94

 Description   

As far as I can tell the "–quite" flag doesn't seem to make the logs any less verbose. When I spin up a new instance of the mongo docker image it produces a whole bunch of noise which makes it easy to mess logs which are actually important.

Hi Callum,

Chances are that --quiet is working as intended, which is to say it is suppressing:

  • output from database commands
  • replication activity
  • connection accepted events
  • connection closed events

There is always going to be some amount of output from the process by design. During startup, the amount of output can be rather similar, and it appears normal based on the sizes you provided. However, your expectation for even less logging is understandable, and it sounds like it would be useful feature to others as well for only displaying critical events.

May I please ask that you submit this same request at feedback.mongodb.com? Given that this is currently normal behavior, this would be considered more of a feature request. 

Regards,

Christopher
