Traffic-Blaster is an efficient C++ application for stress testing a REST server. It opens N connections to a host:port and uses a threadpool to push a high volume of requests on the opened connections. This simulates a very high volume of traffic.
# Example 1: dry run
$ ./traffic_blaster --host server001.company.com --port 80 --endpoint /endpoint?qs=10 --request request.json --connections 2 --threads 2 --volume 5 --delay 100
Settings:
Host: server001.company.com
Port: 80
Endpoint: /endpoint?qs=10
Request file: request.json
Volume: 5 requests sent on each connection
Response Wait Timeout: 5 seconds
Connections: 2 total connections to be opened
Threads: 2 total threads pushing to all available connections
Delay between sending requests: 100(ms)
Logging enabled: 1. If true, prints additional information to console
