Gatling for Websocket Protocol

Reading Time: 3 minutes Hello there, In this blog, we shall discuss about the WebSocket protocol. Further in the blog we will also try to learn to create a simple Gatling Scripts for this protocol as well. But without jumping to the Gatling script we shall learn about WebSocket Protocol. So lets begin. How webSocket is different from HTTP? WebSocket and HTTP, both of these are communication protocols which Continue Reading

Gatling for SSE Protocol

Reading Time: 3 minutes Hi Guys, In this blog, we shall discuss about the SSE(Sever-Sent Events) protocol. Further in the blog we will also try to learn to create a simple Gatling Scripts for this protocol as well. Let’s not jump directly to the script part, but first let us learn about the SSE protocol and how it is different from WebSocket protocol. How SSE protocol is different WebSocket Continue Reading

Going stateful with Gatling Session API.

Reading Time: 4 minutes Hello Everyone, In our previous blog post Gatling feeders and feeder strategies we have discussed what are the different ways to inject the data in our simulation from different data sources.  Today we will discuss: Real-time use case (Problem Statement)  Solution: Gatling Session and Session API Injecting Data with Gatling session API Extracting data with Gatling session API Some common exceptions Real-time use case (Problem Continue Reading

Accelerate performance with Gatling:3.3.0-Warmup

Reading Time: 5 minutes Hello, welcome to the first blog of our Gatling series. Objective is to see how we can accelerate the performance of the product with a tool like Gatling and how to easily integrate with our code base to run the test on different environments. This series is totally based on my personal experience so I have tried to cover all the possible scenarios that I Continue Reading

Jmeter Load Testing:Send and Receive Email

Reading Time: 2 minutes Email notification, send email and retrieve email is a important part of any company or organisation so if you have your email server and want to know the email performance of email server then we can use the jmeter. Beauty of jmeter is it gives the power in your hand you can measure the performance of send email same as received email performance.So we can Continue Reading

Tutorial 3:Monitor CPU Utilization with Dynatrace

Reading Time: 2 minutes This is last blog of this series in this we will read how to monitor CPU Utilization by Dynatrace. Why we always need  memory  analysis ? We need memory analysis is to optimize garbage collection (GC) in such a way that its impact on application response time or CPU usage is minimized. If garbage collection has a negative impact on response time, our goal must be Continue Reading

Tutorial 2: How To Diagnose using Dynatrace (APM) Tool

Reading Time: 3 minutes In my Last blog, we went through the introduction of Dynatrace Digital Performance tool. In this subsequent blog, we will learn how to diagnose this tool. Once you open the Dynatrace client,  you will be landed to a dashboard page where you can easily view recent activity of all the requests to the server (picture given in the last blog). We can easily connect with different hosts by Continue Reading

Tutorial 1: DYNATRACE -Application PERFORMANCE Monitoring (APM) TOOL

Reading Time: 2 minutes Hi Everyone, In This blog we will discuss about a performance tool  – Dynatrace which we are using now-a-days in Knoldus for Performance Testing and We would be running this blog as a series and we would be looking at various aspects of Performance Testing with this blog. The aim includes; What is Dynatrace? How does this work? Benefits of Dyntrace When we develop a new application, we Continue Reading

Gatling Integration with Play

Reading Time: 2 minutes I have started working on a project which require stress testing using Gatling. I Setup the sbt project on which gatling is working fine. But when I try to integrate it using play framework, it doesn’t work. The project structure for both are different so it doesn’t work for both the project in the same manner. Your build.sbt should be  like this: import _root_.io.gatling.sbt.GatlingPlugin import Continue Reading

Improve Memory Usage and Performance of Application Using Yourkit Profiler

Reading Time: 3 minutes In this blog we are walking through how to improve performance of application using Yourkit profiler it is  helpful for both Tester and Developers. Your Kit is big achievement in the evolution of the profiling tools. It is intelligent tools for profiling java , .net and ( JVM support languages)  based applications. It is often important to check memory usage and memory used per process on servers Continue Reading

Jmeter Data Extraction from File

Reading Time: 2 minutes When we talking about Performance Testing, Some time we faces the scenario like we have to extract data from file. Extraction data from file is very important part of performance testing. In this blog, we will learn Data Extraction from File using Jmeter. First of all we will create a .xlsx file. which consist our test data. Now we open the jmeter and make a Continue Reading

Performance Tuning Java Applications on Google App Engine

Reading Time: 5 minutes Performance Tuning is one of the stages of taking your application to production which you can seldom avoid. Irrespective of the fact whether you have taken all good performance practices into account, there is something or the other which needs to be tuned before the application is production ready. Performance Tuning takes a different turn when your application is supposed to run on the cloud. Continue Reading
