Dec 3, 2020 · The rps option throttles how many requests per second are sent. del() Issue an HTTP DELETE request. First, in the tab itself, note the number of HTTP requests that passed against the total number of requests. 00-10. Feel free to use your own load testing tools, for example: As the endpoint we're testing is using SSL, each request will also be preceded by an options request, making the total average displayed by k6 around 20 per second. When analyzing API endpoint performance, the load is generally reported by request rate. check the instances of EC2 and details regarding the CPU (you can check requests per seconds as per selected cpu) and memory. 5 iterations / s, or try to start a new iteration every 667 ms, rate: 50, timeUnit: '1s' means “try to run 50 iterations every second”, that is, 50 requests per second (RPS), if there is one request in our iteration, i. Installation is as simple as running the New Relic StatsD integration and including New Relic StatsD as an output in your k6 load testing script. To illustrate that: open your Chrome (or browser of choice) open the devtools (F12 in chrome) select the network tab The desired rate of 30 iterations started every 1 second is achieved and maintained for the majority of the test. # Execute load test make load-test Test Results. Set the iteration rate to the requests per second target divided by the number of requests per iteration. This article will provide a detailed overview of how to achieve this with K6 scenarios. Including Transactions-per-Second in CI/CD. May 12, 2023 · Hello Folks, Performance testing is an important aspect of software development, helping testers ensure that their applications can handle heavy loads and maintain performance under stress. , but am having issue writing the flux query. instead of ~+100rps I expected to see load in ~1rps May 6, 2021 · Finally, we see the total amount of requests per second and the volume of data transferred. 1000 with acceleration during for N minutes by option target in the stages — I see that load has increased by ~+100rps in peak, although option "rps" according to k6 documentation is "The maximum number of requests to make per second, in total across all VUs" option i. Context: a new test to group test logic. We want 200 requests per second across the entire load test, so we divide 200 by 0. Thus you can monitor tests as they run, or store the results to visualize at your convenience. Sep 3, 2015 · Measuring requests per second. K6 is a modern, developer-friendly load testing tool. if more than that it will stop the server or hangs the VM.

K6. Slave is read only for statistics and reporting. So, for example, if your API response time is 500ms for 100 requests per second, it will increase up to 800ms for 1000 requests per second. To reach a request-rate target (RequestsRate), follow this approach: Set the rate frequency to the time unit of the target. MySQL handled 2,400 requests per second. Here you can find the documentation of the constant-arrival-rate executor: Constant arrival rate I think you set it correctly (3000 iterations / 1 sec) if 1000 vus are capable to handle this rate. Mar 30, 2024 · One common use case for K6 is to simulate a specific request per second rate while keeping the number of virtual users (VUs) constant. 53 requests per second. how long did the remote server take to process the request and respond, without the initial DNS lookup/connection times). We'll write K6 scripts to simulate user traffic on our application and compare metrics like average response time and the number of successful requests per second. request() Issue any I would like to use K6 in order to measure the time it takes to proces 1. 53… turns out we’ll need about 378 concurrent bots running this script to generate 200 requests per second sustained throughput. Jul 24, 2019 · Nice! We were able to handle ~279k requests in a 14 second timeframe with an average response time of 32ms and no errors!

Dec 25, 2023 · Output example of executing a k6 test - data_received: The total amount of data received from the target server during the test. Having started with 2 VUs (as specified by the preAllocatedVUs option), k6 automatically adjusts the number of VUs to achieve the desired rate, up to the allocated number Define the HTTP requests and methods you want to use. I see that k6 outputs requests per second in the console under the http_reqs metric, but I don’t seem to be able to fetch that number in the Advanced Examples using the k6 Scenario API - Using multiple scenarios, different environment variables and tags per scenario. But there’s a problem with this initial test that gives k6 an advantage. This includes any intervals between samples, as it is supposed to represent the load on the server. Virtual user (Or VU). 0 influxDB using this library: GitHub - grafana/xk6-output-influxdb: k6 extension to output real-time test metrics to an InfluxDB 2. k6 has a way to set VUs, but VU does not make a new request until the previous iteration is finished. The total number of completed iterations equals vus * iterations. Especially I miss the rps metric, if I want to test a user flow. Depending on the application, 1,000 RPS isn't actually that high. x database. On the other hand, if no one else is visiting the website, you would need to use at least 80% of the bandwidth in order to cause a DoS, and 80% of 100 Mbps = 80 Mbps, which corresponds to 40 GET requests per second. It’s shown in kilobytes and the rate per second. In some cases, this number of VUs can generate up to 300,000 HTTP requests per second (RPS). You can customize tags as you wish. io/v1beta1 kind: Ingress name: main-route target: type: Value value: 10k What i would suggest is having an ingress resource specifically for this service (load balancing in round robing) and then if you can do autoscaling based on the number of So, 2000 ping request per second from different clients is a base upper limit for a normal server. post() Issue an HTTP POST request. In this case, the test met the criteria for both thresholds. I found several topic about that but still I'm confused how this works. 000. Behaviour of each output can differ, but the Prometheus Remote Write extension attempts to send gathered metrics to the remote write interface each second. Depending on the available resources, and with the guidelines described in this document, a single instance of k6 can run 30,000-40,000 simultaneous users (VUs). I used the constant-arrival-rate to achieve this but I don’t see the expectations are met while using it. A single k6 instance can produce anywhere from thousands to tens of thousands requests per second, depending on a lot of different factors - machine specs, script complexity, VUs, sleep times, network conditions, etc. Expressing our performance goal A core prerequisite to excel in performance testing is to define clear, measurable, service level objectives (SLOs) to compare against. Executors configure how long the test runs, whether traffic stays constant or changes, and whether the workload is modeled by VUs or by arrival rate (that is, open or closed models). It can simulate thousands of requests per second and access Node. Oct 9, 2021 · Capable of handling 30. Third(with batching) , where API {2, 3 and 4} are bundled in 1 request ‘per 10 calls’ to API 1.

If any of the thresholds had failed, the little green checkmark next to the threshold name (http_req_failed, http_req_duration) would be a red cross and k6 would exit with a non-zero exit code. Besides the common configuration options, this executor has the following options: May 24, 2023 · A slow or overloaded API can negatively impact the user experience and cause cascading failures across dependent services. // 10 requests per second timeUnit: '1s Request rate. The simulated users that run separate and concurrent iterations of your test script. For example, I have two POST requests created, I want one to be hit 90% of the test run and the other 10%, to simulate a more busy and less busy endpoints being hit by requests on the same HTTP server. now() to go up - which is not an accurate Stage 3 maintains the stage 2 iteration rate at 600 iterations started per minute over a 4-minute duration. The most proper way of doing this is using some metrics storage and outputting k6 there for the later investigation. Before an arrival-rate scenario starts, k6 first initializes the number of preAllocatedVUs. When the test is complete, k6 prints a top-level summary of the aggregated results to stdout. try to start a new iteration every 20ms This limits memory and ensures that k6 can validate that all thresholds are evaluating defined metrics. 5, darwin/amd64) OS and version: MAC OS 10. you can also tweak KEDA ScaledObject config for testing any paths such as /v1 or /*.
