Basic counters for server monitoring A typical e-commerce application runs in an environment with many different types of servers, including application servers, web servers, and database servers. At a minimum, you should use basic audit counters to monitor all servers while you run performance tests. Let’s quickly review the server types and associated monitoring statistics: …
Trend Method “A general direction in which something is developing or changing” is what the definition of trend means. Client, server, and network statistics can be studied using the trend analysis method. Understanding the WHIWH rule before attempting to understand the Trending technique is helpful. Let’s start by discussing how to interpret the chart and …
This is a technique for deciphering chart patterns by examining and contrasting them before drawing a conclusion. This method consists of two components: A soak test, which helps identify memory leaks in the application, is the best illustration of the pattern method. In the soak test or endurance test, a system is tested under an …
Extrapolate, according to its definition, is the process of applying (a method or conclusion) to an unknowable situation by making the assumption that current trends will continue or that similar procedures will be appropriate. When an application is tested in a scaled-down environment with fewer users, extrapolation is necessary for performance testing. A suitable load …
Filtering out specific requests, transactions, or components from the performance problem culprit list is accomplished using the stripping technique. You can read about the Drill Down method, where we start with a problem and keep looking for the source until we find it, in the previous post. But what to do if more than one …
Drill Down Method By digging down to find the exact cause, you can focus on one problem area at a time and limit your attention to a single component. It is similar to starting your investigation at a general level and digging deeper to determine the precise nature of the problem. Any type of metric …
Correlate Method You would have used the correlation for dynamic values while preparing scripts in Micro Focus LoadRunner. Have you ever heard about graph correlation? If your answer is No then refer to Graph Correlation post first. Because Graph correlation is the base of the ‘Correlate Method’. Graph correlation is a perfect feature of the Micro …
Compare Method According to the ComCorDEEPT approach, the first and most important way of Performance Test Result Analysis is “Compare.” The ‘Compare’ technique is an easy way to compare the specified NFRs to the actual outcome. You may compare the specified vs. real response times to draw conclusions about the outcome, for instance, if the …
WHIWH Rule Performance testing requires a skill to identify bottlenecks. Without mastering this art, it is impossible to be an ideal performance tester. A proper method to locating the bottleneck and its source may be carried out with the use of certain performance test result analysis techniques. Apply the WHIWH rule before beginning an inquiry …
Network-side Result Analysis The examination of network-side performance results is a follow-up to my prior articles on client and server performance analysis and optimization (Performance Test Result examination Basic Level and Performance Test Result Analysis Intermediate Level). Once you have evaluated the client- and server-side performance but are still not satisfied, consider the network performance. …
