Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to r

Use Nmon to monitor Linux system performance, nmonlinux Nmon is a computer performance system monitoring tool developed for AIX and Linux systems by IBM employee Nigel Griffin iths. Nmon can display operating system statistics on the screen or store them in a data file to help you understand the usage of computer resources, adjust the direction and system bottlen

1. Monitor CPU information with Vmstat tools.Vmstat is a Linux system monitoring tool that uses the Vmstat command to get information about processes, memory, memory paging, blocking IO, traps, and CPU activity.R: The number of processes in the running queue; B: The number of processes waiting for IO.SWPD: Used virtual memory size (k); Free: idle memory size; buff: buffer size used; cache: Cached size used.
