ezgh obs datasets sampling <command>Trace sampling keeps some of a dataset’s traces and drops the rest, deciding each trace whole after its spans arrive (tail sampling): keep every error and slow trace, say, and 5% of the rest. A dataset’s policy is its rules, tried in order, and a default. Sampling applies to traces only; logs and metrics are kept as they arrive, and span metrics count every span, kept or not. A dataset without a policy, or with one that isn’t enabled, keeps every trace. The dataset is given by environment, ID, slug (dst_…) or name.
