• 结合zabbix统计/proc/meminfo文件中的内容


    vim memory_status.sh

    #!/bin/bash   #脚本解释器说明
    MemTotal(){
            awk '/^MemTotal/{print $2}' /proc/meminfo    #打印/proc/meminfo文件中以MemTotal开头行的以空格分割的第二列元素的值,单位为kb
    } 
    $
    1 #第一个位置参数,位置参数的值为相应函数名,则会调用相应函数

    :wq!

    chmod +x memory_status.sh

    执行命令:

    ./memory_status.sh MemTotal   获取 /proc/meminfo 文件中 MemTotal 字段的值
