OTLP/JSON Trace — 13-Span Checkout Request (json)
A complete OTLP/JSON trace export: one checkout request across five services as 13 spans, four levels deep, with HTTP, database, RPC and messaging semantic-convention attributes, span events and a producer span. Trace and span IDs are fixed, so ingesting it twice produces identical output.

Testing contract
Expected to pass- Scenario
- Import the payload into a trace store or OTLP receiver and reconstruct the span tree from parentSpanId.
- Expected result
- 13 spans across 5 resources rebuild into one tree rooted at span 00f067aa0ba902b7 with a 148.2 ms root duration and no orphans.
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/JSON Trace — 13-Span Checkout Request (json)” is a deterministic Novus Examples fixture for Observability, JSON parsing, Schema validation. 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 · 28,618 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.
Code examples
import json
with open("otlp-trace-checkout.json") as f:
data = json.load(f)
print(type(data), len(data))Related files
- jsonOTLP Trace — Empty but Valid Batch (json)A structurally valid OTLP export containing no spans at all — what an exporter sends when every span in the interval was sampled out. The empty-input case that ingestion code routinely mistakes for an error.
- txtB3 Propagation — Single and Multi-Header Forms (txt)B3 context propagation in both shapes — the compact single b3 header including the debug flag, a legacy 64-bit trace ID and the sampling-only form, plus the five X-B3-* multi-header fields — with two malformed values that must be rejected.
- jsonOTLP Trace — 48-Span Linear Chain (json)A single-service trace 48 levels deep — a recursive GraphQL-style resolver where every span is the child of the one before it. A depth fixture for waterfall renderers, tree-layout code and any parser that recurses over parentage.
- jsonOTLP Trace — 60-Way Parallel Fan-Out (json)One root span with 60 overlapping children — a scatter-gather query across database shards. The counterpart to the deep-chain fixture: shallow but very wide, which is what breaks waterfall layouts that assume spans do not overlap in time.
- jsonOTLP Trace — All-Zero Trace and Span IDs, Intentionally Invalid (json)A trace whose trace ID and root span ID are all zeroes — the value an uninitialised context produces. Intentionally invalid: the specification defines all-zero IDs as invalid, so a conformant receiver must reject the spans instead of creating a permanent bucket that every broken service writes into.
- jsonOTLP Trace — AnyValue Attribute Type Matrix (json)One span carrying every OTLP AnyValue kind — string (plain, Unicode, multi-line, empty), int64 encoded as a JSON string, double, bool, array, nested kvlist and base64 bytes. Includes an integer above 2^53 to catch decoders that route int64 through a JavaScript number.
