这篇文章主要介绍了如何实现统计cpu内存和使用率的shell脚本代码，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
代码如下:
#!/bin/sh
clear
while ((1>0))
do
NET=$(netstat -anp | grep 1000 | grep EST | wc -l)
PRC=$(ps aux | grep thread1 | grep -v grep | grep -v SCREEN | awk '{ print " CPU: " $3 "%, MEM: " $4 "%, RSS: " $6/1024 "M, VSZ: " $5/1024 "M, PID: " $2 ""}')
tput sc; echo -n -e "\b"; tput rc;
echo "SRV: thread1, NET: $NET, $PRC"
echo ""
NET=$(netstat -anp | grep 1011 | grep EST | wc -l)
PRC=$(ps aux | grep thread2 | grep -v grep | grep -v SCREEN | awk '{ print " CPU: " $3 "%, MEM: " $4 "%, RSS: " $6/1024 "M, VSZ: " $5/1024 "M, PID: " $2 ""}')
tput sc; echo -n -e "\b"; tput rc;
echo "SRV: thread2, NET: $NET, $PRC"
echo ""
NET=$(netstat -anp | grep 1022 | grep EST | wc -l)
PRC=$(ps aux | grep thread3 | grep -v grep | grep -v SCREEN | awk '{ print " CPU: " $3 "%, MEM: " $4 "%, RSS: " $6/1024 "M, VSZ: " $5/1024 "M, PID: " $2 ""}')
tput sc; echo -n -e "\b"; tput rc;
echo "SRV: thread3, NET: $NET, $PRC"
echo ""
NET=$(netstat -anp | grep 1033 | grep EST | wc -l)
PRC=$(ps aux | grep thread4 | grep -v grep | grep -v SCREEN | awk '{ print " CPU: " $3 "%, MEM: " $4 "%, RSS: " $6/1024 "M, VSZ: " $5/1024 "M, PID: " $2 ""}')
tput sc; echo -n -e "\b"; tput rc;
echo "SRV: thread4, NET: $NET, $PRC"
echo ""
NET=$(netstat -anp | grep beam.smp | grep EST | grep 222.222.18.222:800 | wc -l)
PRC=$(ps aux | grep thread | grep -v grep | awk '{CPU += $3} {MEM += $4} {RSS += $6} {VSZ += $5} END {print "CPU: " CPU "%, MEM: " MEM "%, RSS: " RSS/1024 "M, VSZ: " VSZ/1024 "M, " " "}' | awk 'END {print}')
tput sc; echo -n -e "\b"; tput rc;
echo "SRV: All, NET: $NET, $PRC"
echo ""
sleep 0.5
tput cup 0 0
done
