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 …
Automatic Correlation for LoadRunner The automated correlation denotes that, following script generation and replay, after applying some predefined or manually applied conditions before recording, the LoadRunner (VuGen) discovers the dynamic value. You can use the automatic correlation to: R3 (Rule, Record, Replay) can be used as a general guideline for automatic correlation techniques. Let’s go …
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 …
LoadRunner Correlation overview The term “map” describes how dynamic values received from the server are processed. This dynamic data, such as session ID and authorization token, are the distinguishing values that are generated by the server for security purposes. Dynamic values can also relate to site content, such as dropdown options, dates, item and product …
