Usage with multiple flows

[vitalii-diachkov-sumup]

It is still not 100% clear for me from the docs on how it should be used with multiple flows. Imagine I have multiple flows in node-red that all have http in node that triggrers the request, then couple of http request nodes inside that makes API calls to my internal services and collects some data and http response at the end.

If I want to enable OpenTelemetry tracing, should I add an OTEL to each node individually, or should I only create it once somewhere and it will work for every node automatically?

The reason I am asking is that I've added this node and its only creating traces and spans in that flow, but if I try to add another OTEL node to other flow my node-red instance is just crashing and the container restarts

Hello,

The docs says:

Add OTEL node once (to any flow),

So… you have to add OTEL node only once (on one flow only, no matter which one, it will handle all the flows) 😉

If you do not find expected traces, you can open an issue with the relevant configs and logs.

Thanks for the answer, I'll try to dive deeper on why am I not getting the traces
