Gor
Gor is a set of specialized utilities for recording, replaying, and shadowing network traffic to validate system behavior under real-world conditions. It functions as an HTTP traffic recording tool, a network traffic capture engine, and a system for duplicating live production traffic.
The project provides capabilities for recording real-time HTTP network traffic and storing it for later playback or analysis. It can duplicate live production network traffic and redirect it to a staging environment in real time, or replay recorded network requests against a target environment to validate system behavior under real-world loads.
The tool covers broad traffic management areas including non-intrusive traffic capture, network traffic replay for validating code deployments and infrastructure changes, and network traffic shadowing for stability testing in secondary environments.
Features
- Traffic Shadowing - Duplicates live network traffic and forwards copies to a separate target environment in real time.
- Regression Test Replayers - Replays captured production traffic against the system to verify runtime behavior and identify functional regressions.
- Traffic Recorders - Captures real-time HTTP network traffic and stores it for later playback or analysis.
- Local Packet Captures - Intercepts and records network packets locally on a device via a non-intrusive listener.
- Network Traffic Capture Engines - Implements a background listener that records HTTP requests from network interfaces without interrupting the primary application path.
- Network Traffic Captures - Records real-time network requests in the background to facilitate shadowing and load testing without interrupting the critical path.
- Network Traffic Replay Tools - Captures and replays sequences of network requests to validate code deployments and infrastructure changes.
- HTTP Request Replayers - Replays recorded HTTP requests against a target server to simulate real-world load and identify regressions.
- HTTP Load Testing - Provides high-volume replay of recorded HTTP requests to measure the performance and stability of web services.
- Load Testing Tools - Simulates real-world user traffic at scale by replaying recorded requests to evaluate system performance.
- Network Traffic Storage - Persists captured network traffic to local storage for later retrieval and playback during load testing.
- Pod Traffic Mirroring - Copies live network traffic to secondary destinations for monitoring and analysis without impacting the main data path.
- Network Traffic Analyzers - Captures and inspects HTTP requests and communication streams to debug system behavior using actual network data.
- Asynchronous Packet Listeners - Implements non-blocking background listeners to capture network packets without interfering with the primary application thread.
- Destination-Based Routing - Directs replayed or shadowed traffic to specific destination IP addresses based on configurable environment rules.
- Network Programming - HTTP traffic replay in real-time.
- Software Tools - HTTP traffic replication tool for production testing.
