Opentelemetry: setting span time?

danielbr — Tue, 05 Apr 2022 14:25:05 GMT

Hi,

I'm able to capture spans with Oneagent.
However, in my app I try to set a defined time for the spans:

Span span1 = spanbuilder1.setStartTimestamp(timestamp1.getTime(),TimeUnit.MILLISECONDS).startSpan();
span1.end(endtimestamp1.getTime(), TimeUnit.MILLISECONDS);

However, on the PP I see the recorded times.
Am i doing something wrong or is this feature not yet available ?

Hi Daniel,

Actually custom timestamps are not supported, but support for this is on the roadmap.

Best

Hi Harry,
Really appreciate your answer, I've been busting my head over this!

May I ask - is this true for both Oneagent and the Trace Ingest API?

This limitation only applies to OneAgent/OpenTel integration at the moment.

For Trace Ingest, custom timestamps are supported (assuming the the used OpenTelemetry SDK supports it, which is usually the case).
