usually indicate that a large number of processes are causing congestion and need to focus on the CPU. Your server will perform some programs normally. So this item always shows some values.By default, Dstat refreshes the data every second.

About 5 things you don't know about Java performance Monitoring-part 2nd: Java process monitoring with JDK built-in analyzer Fully functional built-in analyzers, such as Jconsole and VISUALVM, are sometimes more expensive than their performance costs-especially in systems running on production software. So, in the 2nd

scanning: 1) If the page is not modified, put the page in the available memory list, 2) if the page is modified by the file system, the page content is written to disk, 3) if the page has been modified, but not by the file system modification, the page is written to swap space. Pdflush daemon is used to synchronize the file-related memory pages and synchronize the memory pages to the hard disk in time.

three items during scanning: 1) if the page is not modified, put the page in the available memory list; 2) if the page is modified by the file system, write the page content to the disk; 3) if the page is modified but not modified by the file system, write the page to the swap space. Pdflush daemon is used to synchronize memory pages related to files and synchronize memory pages to hard disks in a timely manner. For example, when a file is opened and imported into the memory, the file is modi

files are synchronized to the hard disk by pdflush. when the memory is insufficient, kswapd and pdflush write the data back to the hard disk and release the memory. Anonymous pages, Anonymous pages, which belong to a process but are not associated with any files, cannot be synchronized to the hard disk, when the memory is insufficient, kswapd is responsible for writing them to the swap partition and releasing the memory.

Article Title: Linux performance monitoring and tuning (CPU ). Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In fact, there are many articles on this part on the Internet. Why is this article still available? There are several reasons why it is the motivation of my tra

All the content in this article is based on JDK 5, which may be different if JDK 6 is used.In the past few days, we have done some performance monitoring work, some of which are worth recording:JDK itself provides many tools based on command lines and guis. It is very useful to learn to apply them rationally.Jmap is a command line program that is used to view the number of objects in the JVM. directly input
