| # ops-lite |
|
|
| A curated 500-case root-cause-analysis (RCA) evaluation set for |
| microservice systems, with manifest-driven causal-graph ground truth. |
|
|
| Each case bundles: |
|
|
| - a chaos-injection ground truth (`injection.json`) |
| - a causal service graph derived from the injection's fault contract |
| (`causal_graph.json`) |
| - the runtime environment snapshot (`env.json`, `result.json`, |
| `label.txt`) |
| - 12 parquet metric tables per case, split into the abnormal window |
| (during fault) and the normal window (baseline) |
|
|
| The corpus spans three open-source microservice testbeds: |
|
|
| | system | n | description | |
| |---|---:|---| |
| | `ts` (Train-Ticket) | 320 | Java/Spring Cloud microservice system, 44 application services | |
| | `hs` (Hotel Reservation / DeathStarBench) | 142 | Go/gRPC microservice system, 9 application services | |
| | `otel-demo` | 38 | OpenTelemetry Demo e-commerce app, 15 polyglot application services | |
|
|
| ## Intended use |
|
|
| Benchmarking RCA algorithms on microservice fault propagation. Each case |
| provides the ground-truth root-cause service(s) and a manifest-derived |
| causal graph against which an algorithm's predicted ranking or path can |
| be scored. |
|
|
| ## Pipeline |
|
|
| 1. **Generation** — chaos faults are injected and observed by AegisLab, |
| an open-source RCA benchmarking platform. A detector confirms each |
| case is observable end-to-end before it enters the candidate pool. |
| 2. **Annotation** — for every observable case, a manifest-driven causal |
| graph reasoner (rcabench-platform v3 `internal/reasoning`) |
| enumerates the fault propagation layer-by-layer from the registered |
| fault manifest, producing the `causal_graph.json` ground truth. |
| 3. **Curation** — a 1464-case raw pool is reduced to 500 via a greedy |
| selector with hard filters (cyclic graphs, lp ≤ 1, frontend-only |
| injections) and soft caps on system / chaos-family / root-service. |
|
|
| This repo card summarizes the released artifact itself. The full |
| generation and selection pipeline will be documented in the associated |
| paper / artifact release. |
