To view the report directly in the terminal, run: Which provides an report in the format seen in the first steps: For more information about Vegeta, refer to the official documentation.

I would advise you to not try it many times, HTTPBin.org might block your IP thinking you are DDOSing their system. There are many advanced things that can be done with Vegeta load testing. Let’s have a look at this in the example below with a couple of GET requests: Now similar to the first example with the text output run this command in the folder the targets.txt file is created: vegeta attack -duration=5s -rate=5 --targets=targets.txt | vegeta report --type=text. Blogging at Geshan.com.np. Vegeta is a go-lang binary (and library) so installing and using it is a breeze. Vegeta tool does not provide any way to communicate with it using HTTP interface. The -title flag allows specifying a title for the plot. Local tests are fine too still they might not give an accurate picture of how the server will behave on load. Get them here.

We once had to open up an API to a much higher load than it would normally get. I had once used Vegeta to load test Google Cloud Functions and Google Cloud Run with the same code to see the response time difference between those two for a talk. All thanks to Vegeta it was much easier than using another tool or service. Your application/API is deployed on a server (staging/production) to test it. Break the rules, improvise ... reengage known and go into the unknown. Vegeta binaries are available on GitHub Releases. A single Vegeta client was able to produce the level of throughput equivalent to 15 apache bench clients in our load test. All we need is the HTTP Request Sampler. In this post, we will discuss how to use Vegeta for your load testing needs with some GET request examples. First, have a look at the command that we used to run a single Vegeta client. It's a versatile tool that can be used as a command-line utility or a library. For the load test to work correctly we need to have a lightweight api shim that will accept incoming requests and handle process spawning in the background. DEV Community – A constructive and inclusive social network for software developers. Load testing allows testing the behaviour of an application under real conditions by simulating concurrent user requests. You can also install Vegeta on a Mac with the following command: If you already have go-lang installed on your machine and GOBIN in your PATH, you can try to start your Vegeta load testing journey: You should see a version number displayed. We can get a graph output with the below command: Let’s analyze how we used Vegeta for load testing httpbin.org here: Then we set up the URL for vegeta attack by echoing GET http://httpbin.org/get, This step is when we “attack” (a.k.a load test) httpbin servers at 10 requests per second for 30 seconds duration (so in total 300 requests in 30 seconds) we also specified that we want the output at results-vegeta-httbin-get.bin file, Now this result is like a binary that can’t be read easily so the next thing is we read the contents of this binary file with cat and passed it to vegeta plot with a fancy title and filename to get the HTML file.
