05/22/2022, 3:25 PMThe baggage entries are only propagated across the process boundaries. They don't get added to span unless you get the baggage entries from current context and enrich the span in your code.

05/22/2022, 3:26 PMOh ok. Then how do I set an attribute across all spans ?
s
Srikanth Chekuri
05/22/2022, 3:30 PMYou would use Resource if you need a way to add attribute across all spans https://javadoc.io/doc/io.opentelemetry/opentelemetry-sdk-common/latest/io/opentelemetry/sdk/resources/package-summary.html.

05/22/2022, 3:38 PMThank you very. Can you point point to some resource on how to use
Resource APIs
Srikanth Chekuri
05/22/2022, 3:46 PMHere is a SDK configuration guide which also includes the Resource https://github.com/open-telemetry/opentelemetry-java/blob/main/docs/sdk-configuration.md#configuring-an-instance-of-the-sdk. The Resource conceptually represents entities and is the closest thing to which can add attributes to all spans but not doesn't make sense to include user or dynamically changing values.

05/22/2022, 3:48 PMWhat are you trying to achieve?

05/22/2022, 3:49 PMI want to tag a api request with user id so that I can search the api request by user id.

05/22/2022, 3:51 PMWhy do you have to tag it with every single span? Just tag the top most server span and you should still be able to search with it.
Srikanth Chekuri
05/22/2022, 3:52 PMThe span is part of trace and you will see the full trace with it

Aravind Chintalapalli
05/22/2022, 3:52 PMoh ? even if I tag one of the span in a trace, will I get the entire trace while searching ?
s
Srikanth Chekuri
05/22/2022, 3:54 PMCorrect

nice @Aravind Chintalapalli Can you share what finally worked for you? Would be helpful for people who visit this thread in future

05/23/2022, 4:41 PMI was not able to set dynamic value across spans, but I was able to set the dynamic value as a tag on one of the spans and I was able find the whole trace by searching for the tag.
