If you need to track the system calls that a process makes and receives, the first thing to think about is what? You probably think of strace, you're right. Monitor raw network traffic from the command line what tools do you use? If you think of tcpdump, you have made a wise decision. If you happen to need to keep track of open files (in other words the Unix language is: Everything is file), chances are you'll use lsof.Strace, Tcpdump, and lsof are re

Article Title: Use Inotify to monitor Linux File System events. 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. Inotify is a file system event monitoring mechanism and is planned to

When we manage servers, the ipvsw system is more intuitive, including cpu usage, memory usage, and so on, as long as the task manager in the Remote Desktop is clear at a glance. However, in a linux environment, it is not that easy. In particular, large websites run on servers or vps. If server performance consumption cannot be detected in a timely manner, the website may be accessed during peak hours, I don't know what the problem is. Today we will in
