Can not filter by “Duration (μs)> =” in the UI

the duration query depends a lot on how your apps are instrumented and which storage is in use. For example, we no longer support duration query on the "cassandra" storage type.

@longinhit it's supported in the cassandra3 storage, if you're able to upgrade.

Is this the same issue with the Elasticsearch backend? Results that shouldn't be are getting filtered out.

what instrumentation are you using? are the traces you are sending reporting span.duration? You can check by using the api as /api/v1/trace/trace-id-in-hex?raw

fyi here's a status report on libraries that properly address timestamp and duration openzipkin/openzipkin.github.io#49

We are using brave v3.15.1. We were previously using v3.9.1 until a few weeks ago and that is around when we started seeing the problem (upgraded brave and zipkin-server jar).

We do use a custom jmeter setup to run automated tests and we generate a traceId before sending the initial request so that we can log traceIds alongside request logs. Using the raw endpoint I am seeing sr and ss on the top-level span but it looks like the duration field is missing from that span.

Again, this was working previously - is this something that has changed during the deprecation of the SpanCollector classes? I can try switching to the Reporter classes to see if that fixes it.

I verified that when I hit an endpoint using curl and specifying a traceId in the headers the duration does not show up. Without the headers it does.

And we found this comment that says a timestamp/duration won't be kept if a traceId is sent - perhaps the cause? https://github.com/openzipkin/brave/blob/181a2f438e5142510cb72eefc723839bc525fe4d/brave-core/src/main/java/com/github/kristofa/brave/ServerRequestInterceptor.java#L50

Does a backfilling as mentioned in the comment ever happen?

I'll look into this now. It it is a root span, we should be setting duration for sure. Stand by and thanks for gathering the details!
