dstat: versatile tool for generating system resource statistics
During my work with computers, I like to check the usage of system resources in my network. Sometimes a running process takes up too much CPU load, or the disk I/O goes too high. To get a clean picture of how much resources are being used by a client, I used ifstat, top(1) and iostat(1).
Since I have found out about dstat, I can cleanly check out all the system resources used by my computers. dstat prints all the different type of resources in separate columns on a single line, so it is very easy to see the system load globally.
Though dstat gives global statistics about the currently used system resources, it might replace several tools in one.
