Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, πŸ‘‹, I’m Ryan HefnerΒ  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you πŸ™

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:

  • πŸ“ˆ Supercharge Web Performance: Benchmark your web services to spot performance bottlenecks and optimize your application for top-notch speed and reliability.
  • πŸ”„ 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.
  • πŸ” 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-monkey

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.

Examples

1: Basic GET Request Benchmark

metrics-monkey --url https://jsonplaceholder.typicode.com/posts --method GET --requests 1000 --concurrency 50 --timeout 10 --duration 60000

Description: 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

Benchmark Results
------------------------------
  Requests per Second: 163.67
  Latency (ms):       
    Avg:       250.38ms
    Stdev:     341.99ms
    Max:       2.26ms
  Throughput (MB/s):   0.00
  HTTP Codes:         
    200xx: 943
------------------------------

Total time: 6s

2: POST Request with Custom Headers

metrics-monkey --url https://api.example.com/data --method POST --requests 500 --concurrency 20 --timeout 5 --headers '{"Authorization": "Bearer my-token"}' --body '{"key": "value"}' 

Description: Sends 500 POST requests to https://api.example.com/data, including a custom Authorization header and a JSON body. The tool will use a concurrency of 20, a timeout of 5 seconds per request

Example Output:

progress [========================================] 100% | ETA: 0s | 500/500

Benchmark Results
------------------------------
  Requests per Second: 75.41

  HTTP Codes:         
    0xx: 500
------------------------------

Total time: 6s

3: PUT Request with Extended Duration

metrics-monkey --url https://api.example.com/update --method PUT --requests 2000 --concurrency 100 --timeout 15 --duration 120000 

Description: Performs a PUT request to https://api.example.com/update with 2000 requests and a concurrency of 100. The test will run for 2 minutes (120,000 milliseconds) with each request timing out after 15 seconds. The results will be displayed in plain text format.
