Question

Hi team does SigNoz support Sampling ``` sampling definition Sampling is frequently used to reduce the number of traces that are collected and stored in the backend This is often desirable because it is easy to produce more data than can be efficiently stored and queried Sampling allows us to store only a subset of the total traces produced ```

< Quy Bui> are you deploying in k8s or a single VM

Quy Bui · Answer

No I am not deploying yet May I know what is open source license of SigNoz

Quy Bui · Answer

It seems to be that SigNoz only supports head based sampling provided by OpenTelemetry It does not support tail based sampling

Ankit Nayan · Answer

If you can set up tail based sampling using OpenTelemetry we can help you set up `spanmetricsprocessor` which calculates APM metrics before you sample the spans and hence the APM metrics will be correct as they will be based on 100 sampled data
