Add an error sampler for Log probes by jpbempel · Pull Request #10638 · DataDog/dd-trace-java

jpbempel · 2026-02-19T14:56:36Z

What Does This Do

log template only probe are rate limited to a higher rate. if condition is set and returns an error, we don't want to return a snapshot at the same rate just for reporting the condition evaluation failure. So we are introducing a specific sampler at 1/s rate to report error in that case.
