Recommended way to not ship logs from some apps?

GitHub - superfly/fly-log-shipper: Ship logs from fly to other providers is wonderful, but there are some very noisy apps I don’t actually care about, and some apps where I want to handle log shipping myself in order to set more fields. Is there a good way to do this?

Fly app’s name is a NATS subject (ref) that you can choose to not subscribe to: Ship logs from multiple apps - #5 by dusty

According to the github readme, the subject is of form logs.<app_name>.<region>.<instance_id>.

Another (obvious) way is to filter out logs after it is sent to the sink (like honey-comb, logdna, papertrail etc): fly-log-shipper: staging vs. prod & then hiding individual server logs - #2 by mhostetler
