 Tail sampling is where the decision to sample a trace takes place by considering all or most of the spans within the trace. Tail Sampling gives you the option to sample your traces based on specific criteria derived from different parts of a trace, which isn’t an option with Head Sampling.
 
 ```yaml
-  # Samples spans with status codes ERROR (OK spans dropped) and 
-  # traces which have a duration longer than 500ms.
+  # Sample 100% of traces with ERROR-ing spans (omit traces with all OK spans)
+  # and traces which have a duration longer than 500ms
