nodejs-logreplay is a (very) simple Node.js application which parses the standard Apache access log and replays the requests, in real time, against a target server.
nodejs-logreplay was developed to assist in load testing web server(s) by replicating the same request pattern that production systems experience. This helps us determine how code modifications will perform in production before they are deployed.
Easy:
- Install Node.js and the following packages from npm:
- lazy
- konphyg
-
Clone this repository onto the server you wish to launch your load test requests from
-
Copy the provided configuration file
