Questions about the combination of Java and beyla

[hearter-cmd]

How does it support Java? When I tried, even if I passed the traceparent manually, it could not capture the tarceparent. Is there a problem with my settings?

[hearter-cmd]

Even if I pass the traceparent, it cannot be captured. Only when it is not passed, it can be used normally when it is generated by itself, but traceid needs to be used in the program. The ebpf option is also enabled. But when I read the log, it always generates new

[grcevski]

Can you please share your configuration?

To properly support context propagation we need to have the following config:

ebpf:
  context_propagation: "all"
  track_request_headers: true

[hearter-cmd]

discovery:
  instrument:
    - open_ports: 49083,8080
ebpf:
  context_propagation: "all"
  track_request_headers: true
instrumentation:
  trace_context:
    override: false
    headers:
      - name: traceparent
        format: w3c

I tried to change "context_propagation" to "headers", which was useless.
I try to check the debug log, see that it is always "Generating new"

[hearter-cmd]

JDK8 + SpringBoot。
I tried to debug in the program and saw that its request did have a traceparent

[hearter-cmd]

discovery:
  instrument:
    - open_ports: 49083,8080
ebpf:
  context_propagation: "all"
  track_request_headers: true
instrumentation:
  trace_context:
    override: false
    headers:
      - name: traceparent
        format: w3c

I tried to change "context_propagation" to "headers", which was useless.
I try to check the debug log, see that it is always "Generating new"

[grcevski]

any chance we can get a log with BEYLA_LOG_LEVEL=debug and BEYLA_BPF_DEBUG=true?

[hearter-cmd]

Or Traceparent has to be the first one?

Or does it only support POST requests?
