metrics-monkey ππ
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:
- π Supercharge Web Performance: Benchmark your web services to spot performance bottlenecks and optimize your application for top-notch speed and reliability.
- π 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.
- π Assess API Dependencies: Verify if the APIs you depend on can withstand the load and determine their maximum capacity.
Installation
You can install metrics-monkey via npm:
npm install -g metrics-monkeyUsage
metrics-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).
Examples
1: Basic GET Request Benchmark
metrics-monkey --url https://jsonplaceholder.typicode.com/posts --method GET --requests 1000 --concurrency 50 --timeout 10 --duration 60000Description: Benchmarks a GET request to https://jsonplaceholder.typicode.com/posts. The test will issue 1000 requests with a concurrency of 50, a timeout of 10 seconds per request, and will run for 6 seconds.
Example Output:
progress [======================================--] 94% | ETA: 1s | 943/1000
