How to find out top 10 CPU and Memory Consuming Process in Linux

In this article, we will show how to find out the resource consumption in a Linux box to figure out the exact issue? “ps” command is a most powerful and popular to achieve our requirements.

The command “ps” command has a lot of options to optimize output as per our requirements.

[root@linuxcnf ~]# ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head PID     PPID   CMD                                              %MEM           %CPU 30118     1        /usr/sbin/mysqld –daemoniz                  16.4               2.4 581       1        /usr/lib/systemd/systemd-jo                    0.4                0.0 991       1        /usr/sbin/rsyslogd –n                            0.2                0.0 985      1        /usr/sbin/winbindd –foregr                     0.2                0.0 2185    985     /usr/sbin/winbindd –foregr                     0.1                 0.0 2482    985    /usr/sbin/winbindd –foregr                     0.0                0.0 762      1        /usr/lib/polkit-1/polkitd -                        0.0                0.0 19524  1904    pickup -l -t unix –u                              0.0                0.0 16405  988     sshd: linuxcnf [priv]                              0.0               0.0 [root@linuxcnf ~]#
