@hanahmily some guess?

[candyleer]

I read the ui codes,maybe it's caused by
in getServiceTopology the nodes don't contain the calls source,only target

If nodes doesn't include all source and target, that should a backend bug.

[candyleer]

Yes ,I am reading the backend method and try to fix it

[candyleer]

@wu-sheng I found the listener public class ServiceReferenceMetricSpanListener implements EntrySpanListener, ExitSpanListener just parse the entry and exit span ,but in cross thread ,we create local span for it, so in es,service_name has service_id (36,44,-42),but service_metric_minute(or hour,day) didn't contain,so cannot found the nodes.

[candyleer]

so that mean if we use cross thread and create exit span in it this issue may reproduce.

[wu-sheng]

I am a little confused. Local span should be not part of analysis, and if EntrySpan and ExistSpan are in different segment, then should no dependencies.

[candyleer]

it seems the dependencies are come from

serviceReferenceMetricUIDAO.getFrontServices(step, startTimeBucket, endTimeBucket, MetricSource.Callee, serviceId)

serviceReferenceMetricUIDAO.getBehindServices(step, startTimeBucket, endTimeBucket, MetricSource.Caller, serviceId)

[wu-sheng]

That is query for front and behind, but, that should not be the problem.
