gatling requests per second

Having a central data feeder was a problem. Each of those requests must contain data for the game (game ID, game name etc. The original request was redirected and Gatling followed the redirection and sent a second request. Latency: Amount of time between a user request and the start of a system’s response. From what I see in the docs, constantUsersPerSec accepts double but it's rounded while reachRps in throttling deals only with seconds. The number of requests per second. Gatling gives a complete analysis of each and every request with graphical representation (charts) in HTML files. Latency against Global RPS – distribution of current request’s latency (process time) related to total request per second of the simulation. We ran this test for the duration of 3 hours. I have very heterogeneous use cases. Gatling is a performance scala library that facilitates running performance tests on your web services/applications. time. Magnus Jensen: 9/22/15 5:41 AM: I have tweaked alle the parameters in gatling.conf that comes with default 60.000 ms to 90.000 but still I get timeout after 60.000. //Magnus. I need to write Gatling scenario that will mimic real users interaction. LocalDate import java. Keeping Gatling code maintainable and reusable is a good practice to create complex performance scenarios. slightly amended to make the maths easier... the ^Z is for 5 seconds out of the 10 seconds test What it allows you to do is to simulate thousands of requests per second on your web application and get a complete report of the execution, with just a few load generators. The quick command supports some other flags to control how the load will be distributed, like rate, which can be used to define the number of new users per second, or the duration, which defines a fixed time for the test. Create a new Scala class in the simulations folder, give it a name of CustomFeeder. More is possible, but we didn't push further. That test lasted for 6 min and generated 1.5 billion requests in total. This will launch 10 virtual users that will do 20 requests each, to the specified URL. One of those features is :concurrency-distribution. Most problems only arise with higher loads. What do you try to do exactly? Load Simulation Graphical Report. We ran the same SSL simulation with JMeter with 10 concurrent users and got 10000 requests per minute, so we are pretty confident that Apache isn't the bottleneck. More details on simulation setup can be found on Gatling Simulation setup page. There’s nothing much that can be inferred from this graph but is useful to find out in case there are failure responses. Final Conclusion. Conclusion. Since this feature was proposed clj-gatling has got quite a lot of other new features. Let's be clear that the real number of requests per sec would depend on the time it takes for a user to complete the scenario. So they should be adapted too. In this case, they are more interested in the rate of requests per second than the number of users. Gatling API provides a wide range of functionalities to support this … We could have a second API, along the current user oriented one, that would let the users configure user launch rate. Source: I'm one of the guys behind k6. Gatling is a powerful tool: with only a few machines, you can simulate hundreds of thousands of requests per second on your web application and get high-precision metrics. It makes it possible to simulate a high number of requests per second with a single machine. gatling. Under the gatling-results directory, go to simulation folder and open ‘index.html’ file. Add in the following code: package simulations import java. So here I’m trying to maintain 5 users constantly per second for the duration of 4 minutes. With instantaneous values, we can find out what time during the test, there were more failures and vice versa. ), in the form of either JSON or XML. Gatling data in simulation.log file. DateTimeFormatter import io. Gatling data in simulation.log file. We will continue to load test a fake e-commerce, and so we are going to improve our Virtual User to make it browse the store in a more humanly way. CPU interrupts per second: The average number of hardware interrupts that a process receives. is it possible to get Gatling to wait more than 60 seconds for a request? The problem you encounter is not the number of requests per second being unreachable by Gatling, it is the number of scenarios started in one second (via the ramp keyword).
