feat(data-pipeline)!: include reason for chunks dropped telemetry by ekump · Pull Request #1449 · DataDog/libdatadog

ekump · 2026-01-14T21:20:19Z

What does this PR do?

When we drop trace chunks due to a problem we emit telemetry, but we weren't including the reason tags. We also were not emitting chunks dropped telemetry for chunks dropped for valid sampling reasons. This PR addresses both issues. Now telemetry should have one of the following reasons tagged for trace_chunks_dropped:
p0_drop
serialization_error
send_failure

Motivation

More accurate telemetry is good

Additional Notes

breaking change: The telemetry module in libdd-data-pipeline was pub. It should be pub(crate).

How to test the change?

Existing tests have been updated.

Omitted due to size.

bantonsson

The change looks good, but there are new lines missing test coverage. Also, how do we deal with semver? This is a breaking change API wise.

bantonsson · 2026-01-16T08:08:55Z

libdd-data-pipeline/src/telemetry/mod.rs

-        if data.chunks_dropped > 0 {
-            let key = self.metrics.get(metrics::MetricKind::ChunksDropped);
+        if data.chunks_dropped_p0 > 0 {
+            let key = self.metrics.get(metrics::MetricKind::ChunksDroppedP0);


These lines seem to miss coverage

Good catch, added some more tests.

how do we deal with semver

@bantonsson - The semver check was correct. It's technically a breaking change because we made a function less public. In reality, no one should have been using that function but the rules are the rules.
