Is it possible to auto instrument nodejs logs in signoz using winston module?

I believe the Winston hooks are in the

auto-instrumentation

system if you're already able to use auto-instrumentation (package or k8s operator): https://www.npmjs.com/package/@opentelemetry/instrumentation-winston In my case, since I'm using NestJS I had to use

nest-winston

to replace Nest's default logger with Winston, then the above module will add the

winston-transport

and now you'll get Logs that are automatically correlated to Traces with a

trace.id

attribute.

I am using docker-swarm infra for node js instrumentation. Does this suggested document will help in my case ? Kindly suggest.

I don't think Docker Swarm has an operator like Kubernetes to automatically inject the auto-instrumentation, so you'll need to at minimum add this: https://signoz.io/docs/instrumentation/opentelemetry-javascript/#send-traces-directly-to-signoz-cloud---n[…]de-automatic-instrumentation-recommended If your main app is already using Winston then that should forward Winston events to Signoz. So asides from adding those packages and

tracing.js

, there is not extensive changes to your app.
