About Recording Spans which meets certain conditions only

[baichu...@shopee.com]

Hi all,

Currently I am working on a project, of which the backend service requires tracing feature. And we want to see only those traces of which the spans contain error message, take too much time to finish or spans have children spans that meet the first two conditions. I guess Sampling can help but have no idea how to set the conditions. Could some one tell me how to do that?

Thanks

Regards,
