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 really great tools that should be part of every

Sysdig: A Tool for Linux Server monitoring and troubleshooting (1) When you need to track the system calls generated and received by a process, what come first in your mind? You may think of strace, so you are right. What command line tools will you use to monitor original network communication? If you think of tcpdump, you have made an excellent choice. If you need to track open files in Unix: Everything is a file), you may use lsof. Strace, tcpdump

Sysdig's chisels is a built-in script for users to track system calls or view system performance bottlenecks, written in a powerful and efficient scripting language, Lua.Today, to share the usage of fdbytes_by, this case can detect that the system's file has the highest I/O usage (not just the file, but also the network I/O), and it can find out which process is reading and writing to it, and can see the details of I/O activity at the kernel level. Application scenarios can be used to see if you

It mainly shows the CPU and memory usage of the system process. Top can quickly check which or which processes are suspending your system. You can see the example of top use here.
