AI is getting better in many areas, so why hasn’t it been used much in performance testing? Creating performance test scripts with AI isn’t very hard. The real challenge is instructing AI, exactly what you need, so it gives you the right results. This is where prompt engineering becomes important. In this article, we’ll show … Read more
Prompt engineering for performance testing involves crafting precise and goal-oriented prompts that effectively assess and evaluate the behavior, reliability, and responsiveness of a system, especially when dealing with AI models, APIs, or software components under various workloads. What is Prompt Engineering? Prompt engineering is the art of writing clear and well-structured instructions (called prompts) so … Read more
In Apache JMeter, various types of post-processors are available to capture dynamic values such as session IDs, authentication tokens, or transaction IDs. These post-processors are designed to extract and store data from server responses for use in subsequent requests. These post-processors are: However, ensuring these captured values are correct is critical to avoid test failures … Read more
The JMeter Plugins Manager is an easy-to-use graphical interface built into JMeter that allows users to browse available plugins. It also helps to install, upgrade or remove plugins. You can also check for updates of the installed plugins. JMeter Plugins Manager is designed to replace the manual process of downloading individual .jar files and copying … Read more
To measure CPU utilization in a cloud-based architecture, or, to be specific, in a cluster (e.g., a Kubernetes cluster, Hadoop cluster, or any distributed system), you need to monitor CPU usage across all nodes in the cluster. Some people might be unaware of the cluster. A cluster is a collection of servers (virtual or physical) … Read more
Following are the Performance Engineering Interview Questions Set #20. Q. 96 How can you correlate database CPU usage with SQL execution in the AWR report? Ans: Examine the “SQL Ordered by CPU Time” section to identify SQL statements consuming the most CPU. Cross-reference with overall CPU usage statistics to assess their impact on database performance. … Read more
