The shell script uses "ten" to view multiple system CPU, specified process CPU, master / slave machine, and memory usage.

Requirements: view multiple machines to see multiple system CPU, specified process CPU, active and standby status, memory usage; and display on one machine

First: set ssh password-free login first

Ssh-keygen-t rsa playing'- f ~ / .ssh/id_rsa does not prompt to generate the secret key directly

Ssh-copy-id-I / .ssh/id_rsa.pub root@ip

Second: query script, which is copied to each machine

Scp / usr/local/src/cpu_men.sh root@ip: / usr/local/src/

Script content

#! / bin/bash

Cpu=top-bn1 | awk-F "[,:%]" / Cpu/ {print $2}'

Men_total=free-m | grep Mem | awk'{print $2}'

Men_used=free-m | grep Mem | awk'{print $3}'

Men_av=awk 'BEGIN {printf "% .0f\ n", (' ${men_used}'/'${men_total}') * 100}'

Num=ifconfig | awk'/ eth.:./ {print $1}'| wc-l

Syseth= "Lord"

[${num}-eq 0] & & syseth= "preparation"

IP=ifconfig | awk-F "[:] +" NR==2 {print $4}'

Pronum=ps aux | grep tdci | grep-Ev "$$| grep" | awk'{print $3}'| wc-l

Procpu=ps aux | grep tdci | grep-Ev "$$| grep" | awk'{print $3}'| xargs

# awk 'BEGIN {printf "%-20s%-10s%-10s%-10s%-20s\ n", "IP-", "status-", "CPU%-", "men%-", "procpu%-"}'

Awk 'BEGIN {printf "%-20s%-13s%-12s%-10s", "' ${IP}'", "'$syseth'", "'" ${cpu} "'",'"${men_av}"'}'

Echo "$procpu (${pronum}" tdic ")"

Third: overall query and display the script on a host: ssh_exec.sh

#! / bin/bash

Awk 'BEGIN {printf "%-20s%-10s%-10s%-10s%-20s\ n", "IP-", "status-", "CPU%-", "men%-", "procpu%-"}' arry= (
