[💡 FEATURE REQUEST]: Filter logs

[devnev]

Plugin

Logger

I have an idea!

In short, add an option to discard logs matching certain properties/patterns.

Motivation:

I have a global loadbalancer set up, which sends health checks to determine if the backend service is healthy. Previously these were handled by an nginx, with access logs disabled for that particular route. I've now changed the loadbalancer so the healthcheck traverses the full stack, all the way into the PHP worker managed by roadrunner. Now roadrunner is logging these requests, causing a lot of noise between logs of actual traffic. It would be great to be able to stop roadrunner from even emitting these logs.

Hey @devnev 👋🏻 Could you please share your RR configuration (.rr.yaml)?

[devnev]

@rustatian I'm probably going to have to redact some of it, is there any particular bit you're looking for?

[rustatian]

Yeah, logs section

[devnev]

Logs section is

logs:
  encoding: json
  level: info
  mode: production

[rustatian]

I think that you may simply use channels. info is needed only for the worker logs (if you need them), for the other plugins you may error log level.

[devnev]

I don't think that works for me as I want to have the http logs in general but filter out certain logs (namely successful healthcheck requests)

[rustatian]

Yeah, in that case it makes sense.
