StellaRouter Performance Testing Pipeline (k6 + Prometheus + Correlation IDs)

Module

Gateway

Status

PARTIALLY_IMPLEMENTED

Description

The StellaRouter gateway service exists but the advisory's proposed k6 performance testing scenarios (A-G), correlation ID instrumentation, and Prometheus metric dashboards for performance curve modeling are not present as source code artifacts. These may exist as devops artifacts outside src/.

What's Implemented

Gateway service with full middleware pipeline: src/Gateway/StellaOps.Gateway.WebService/
Correlation ID middleware: src/Gateway/StellaOps.Gateway.WebService/Middleware/CorrelationIdMiddleware.cs
Gateway metrics: src/Gateway/StellaOps.Gateway.WebService/Services/GatewayMetrics.cs -- Prometheus-compatible metrics
Health monitoring: src/Gateway/StellaOps.Gateway.WebService/Services/GatewayHealthMonitorService.cs
Source: Feature matrix scan

What's Missing

k6 performance testing scripts (scenarios A-G)
Prometheus metric dashboards for performance curve modeling
These may exist under devops/ rather than src/ -- check devops/ directory

Implementation Plan

Create k6 test scripts for Gateway performance scenarios
Add Grafana/Prometheus dashboards for Gateway metrics visualization
These are DevOps artifacts and may belong under devops/perf/ or similar
