For some time, we have been on the internet to show readers how to configure a variety of different performance monitoring tools for Linux and Linux-like operating systems. In this article we will list a series of the most frequently used performance monitoring tools, and provide a corresponding introduction link to ea

Performance Tuning is a process of finding system bottlenecks and adjusting the operating system to eliminate these bottlenecks. Many System Administrators think that performance tuning is like cooking with recipes: simply setting a few system parameters can solve a problem. In fact, this is
Java™platform, Standard Edition 6 (Java SE) focuses on improving performance, providing enhanced tools to manage and monitor applications and diagnose common problems.

Nmon is a monitoring and analysis tool widely used on AIX and various Linux operating systems, and the information recorded by Nmon is more comprehensive, it can capture the usage of system resources in real time while the system is running, and can output the results to the file. The Nmon tool helps to display all of the important performance optimization information on one screen and dynamically updates i

We can see that during baseline statistics, the CPU idle time is between 79% and 100%. the second result shows that the system is in the 100% usage and there is no idle time. from this comparison, we can determine whether the CPU usage should be optimized.2.0 install monitoring toolsMost * nix systems have a bunch of standard
First, what are the key metrics to monitor for software performance testing?
The main purpose of the software performance test is the following three points:
1. Evaluate the current performance of the system and determine if the system meets the expected performance requirements.
2. Look for possible
