OTLP Trace — Negative and Zero Durations, Intentionally Invalid (json)

One span ends 8.4 ms before it started and another has identical start and end timestamps. Intentionally invalid: negative durations poison latency aggregates — a single one can drag a p99 below zero — so this is the fixture for the validation that must sit in front of any duration metric.

end_time_unix_nano must not precede start_time_unix_nano

Testing contract

Expected to fail
Scenario
Compute latency percentiles over the spans in this payload.
Expected result
The negative-duration span is rejected or clamped before aggregation; a zero-duration span is accepted as legitimate, since instantaneous spans are legal.

What is a .json file?

JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format representing objects, arrays, strings, numbers, booleans, and null. It is language-independent, human-readable, and the dominant format for web APIs and configuration. It requires a single well-formed root value.

How to use this file

Use an example JSON file to test parsers and serializers, schema validation, Unicode and number-precision handling, and API request or response processing.

How to use this file for testing

“OTLP Trace — Negative and Zero Durations, Intentionally Invalid (json)” is a deterministic Novus Examples fixture for Observability, Schema validation, Error handling. Structured and plain-text telemetry with known timestamps, levels, request identifiers, and error states for testing log ingestion, correlation, dashboards, and alert pipelines.

Documented properties for this file: JSON · 12,871 bytes. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

Telemetry fixtures use fixed trace IDs, span IDs, and timestamps so ingestion is reproducible run to run. Point your collector, parser, or query layer at the file and assert the documented span tree, metric families, or severity mix; service and host names are invented.

    data = json.load(f)
