Sampling based on dependency result

[xsmrcek]

To impelment better cost cutting policy I would like to have option to sample dependency spans based on their result and duration. Example: I would like to record only dependency calls to CosmosBD which failed or took longer than 1 second.

It is possible now? If so can you please guide me how?
If not, would it be possible to consider implementing of such sampling in future?

@xsmrcek please check out this sample app i have created to filter out spans based on duration. You can do something similar for dependency using the OpenTelemetry Extensions. In this case, you can use a specific attribute to identify a CosmosDB dependency. DurationSpanExporter
