[*]This plugin will check cpu utilization (user,system,iowait,idle in %)
正常测试：
[*]# ./check_cpu.sh
[*]CPU OK : user=0% system=0% iowait=0% idle=100% | cpu_user=0%;70;90; cpu_sys=0%;70;90; cpu_iowait=0%;70;90; cpu_idle=100%;
CPU WARNING测试：
[*]# ./check_cpu.sh-w 0

CPU CRITICAL : user=1% system=4% iowait=0% idle=95% | cpu_user=1%;0;0; cpu_sys=4%;0;0; cpu_iowait=0%;0;0; cpu_idle=95%;
后面两项为设置的WARNING和CRITICAL的阀值，第一项为cpu实际的使用情况。
弄清楚脚本，监控配置就容易多了。。
