const extra = { extra : { duno: "foo", whatever: "bar" } };
app.listen(port, () => {
logger.log('info', 'Example app listening at <http://localhost>:%d', port, extra);
});Harald Fielker

03/17/2023, 6:03 PMYes, that will help for injecting trace context which will help in correlation

03/17/2023, 6:03 PMor does this only work, because trace_id, span_id and trace_flags is already part of the collector ?

03/17/2023, 6:04 PMbtw. I have no issue just talking to the collector via IP - metrics already need this hack

03/17/2023, 6:04 PMAs you can see from the description, it is your winston logger + trace context injected.
