icinga2 借助check_iostat.sh抓取linux服务器的diskIO(硬盘繁忙度)

对脚本进行修改(默认为$12，12为w_await值，14为%util值)

UTIL=`cat $TMP | $AWK ‘{ sum += $14 } END { print sum / NR } ‘`

被监控端：

将改后的脚本拷到nrpe端的/usr/lib/nagios/plugins/下

# vi /etc/nagios/nrpe.cfg  (是-u参数，不带/dev/)

command[check_diskio]=/usr/lib/nagios/plugins/check_iostat -w 180 -c 190 -u sdb1

:wq

监控端：

# vi /etc/icinga2/conf.d/templates.conf

object CheckCommand "nrpe-diskio" {

import "nrpe-common"

vars.nrpe_command = "check_diskio"

}

:wq

#  vi /etc/icinga2/conf.d/services.conf  (shhudson为预定义的os，代表主机group)

apply Service "nrpe-diskio" {

import "generic-service"

check_command = "nrpe-diskio"

assign where host.vars.os == "shhudson"

}

:wq

# service icinga2 restart
