icinga2 借助check_iostat.sh抓取linux服務器的diskIO(硬盤繁忙度)

下載地址：https://exchange.nagios.org/directory/Plugins/Operating-Systems/Linux/Check-Iostat-Updated/details

對腳本進行修改(默認為$12，12為w_await值，14為%util值)

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

被監控端：

將改后的腳本拷到nrpe端的/usr/lib/nagios/plugins/下

# vi /etc/nagios/nrpe.cfg ?(是-u參數，不帶/dev/)

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

:wq

監控端：

# 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為預定義的os，代表主機group)

apply Service "nrpe-diskio" {

import "generic-service"

check_command = "nrpe-diskio"

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

}

:wq

# service icinga2 restart
