Software products often encounter such a situation: product performance is disturbed by unpredictable bottlenecks, resulting inProgramThe processing efficiency is reduced, and the performance is not fully utilized. How to quickly and effectively find the performance bottleneck of software products is one of the content we are interested in. The performance counter is indeed a very powerful tool in Windows server. It allows you to learn the performance indicators of the server in a timely manne

helpAt the same time, this tool is similar to IBM's nmon and supports running in the background, allowing you to collect data from the system at regular intervals to help you analyze trends. In addition, there are even some sample scripts in the downloaded db2top package to help you call them in your own scripts.For example:Db2top-D db_name-I 2-Indicates that the interactive mode is used to monitor the act

Transfer from http://www.tanhao.me/code/151113.html/In developing software on mobile devices, performance has always been one of our most important topics, and we as programmers are our sacred duty to find and monitor the "culprits" in software that cause poor performance in a timely manner, in addition to efforts to improve code quality.As we all know, the iOS platform because of the characteristics of the uikit itself, need to put all the UI operati

Cluster Health Monitor (CHM) is a tool provided by Oracle to automatically collect the usage of the operating system's resources (CPU, memory, SWAP, process, I/O, network, etc.). The CHM collects data once per second. These system resource data are very helpful for diagnosing node restart, hang, instance eviction (eviction), performance problem, etc. of cluster system. In addition, users can use CHM to detect some problems such as high system load, me

Compile a shell script in CentOS to monitor MySQL master-slave replication, Objective: To regularly monitor whether the MySQL master-slave database is synchronized. If not, record the fault time and execute commands to restore the master-slave database to the synchronization state. 1.

Use Ganglia to monitor Hadoop and HBase Clusters 1. Introduction to Ganglia Ganglia is an open-source monitoring project initiated by UC Berkeley designed to measure thousands of nodes. Each computer runs a gmond daemon that collects and sends metric data (such as processor speed and memory usage. It is collected from the operating system and the specified host. Hosts that receive all metric data can display the data and pass the simplified form of th

How to run a front-end test in Ubuntu without a monitor A long time ago, I also used selenium for automated integration testing, using HtmlUnit webdriver, so no display is needed. However, HtmlUnit is always unsatisfactory. Recently, I found this article in my project to solve my long-standing problem: Running Firefox integration testing on servers without monitors. Selenium is a web automation testing fram

Generally, the software for password stealing software obtains the password by monitoring the keyboard. This operation is convenient, but there are also some problems. The password is sometimes not very accurate, some people do not enter the password from the past to the next, of course, there are also a few such people, steal the password, of course, to get the password of those who are careless! You can use the installation hook to monitor the QQ lo

Analysis toolsA free tool for analyzing AIX and Linux performance, the Nmon tool helps to display all of the important performance tuning information on one screen and dynamically update it. This efficient tool can work on any dumb screen, Telnet session, or even dial-up lines. In addition, it does not consume a lot of CPU cycles, usually less than 2%. On the updated computer, its CPU utilization will be less than 1%. Use a dumb screen to display the data on the screen and update it every two se
