M. Monkey generated by Llama 3.1
The metrics-monkey is a no-nonsense, high-performance CLI HTTP benchmarking tool that's a swiss army knife for developers and performance engineers who want to:
- 📈 Supercharge Web Performance: Benchmark your web services to spot performance bottlenecks and optimize your application for top-notch speed and reliability.
- 🔄 Test API Endpoints: Simulate various traffic patterns, including high concurrency, large number of requests, and prolonged durations, to ensure your API endpoints can handle the load.
- 🔍 Assess API Dependencies: Verify if the APIs you depend on can withstand the load and determine their maximum capacity.
You can install metrics-monkey via npm:
npm install -g metrics-monkeymetrics-monkey --url <url> --method <method> --requests <requests> --concurrency <concurrency> --timeout <timeout> --duration <duration> --headers <headers> --body <body> --output <output>Options:
--help:Display the help message with all available options and their descriptions.--url:The URL to benchmark.--method:The HTTP method to use (GET, POST, PUT, DELETE).--requests:The total number of requests to make.--concurrency:The number of concurrent requests.--timeout:The timeout for each request in seconds.--duration:The duration of the test in milliseconds.--headers:The headers to include with each request (in JSON format).--body:The body content to include with POST or PUT requests.--output:The output format (plain or json).
