1.安装IOSTAT工具
# yum install sysstat -y

2.部署脚本
# mkdir -p /usr/local/zabbix-agent/scripts/
# vim /usr/local/zabbix-agent/scripts/zabbix-iostat.sh
#!/bin/bash
ZBX_DEV="$1"
ZBX_METRIC="$2"

# Check iostat util
if ! which iostat 2>&1>/dev/null; then
>&2 echo "Can't find 'iostat' binary in \$PATH"
>&2 echo "Make sure that you've installed 'sysstat' package"
exit 1
fi
# Check args
[[ $# -lt 1 ]] && { echo "Give some more arguments, please :)"; exit 1; }
# Discovering devices and spits out JSON
if [ "$ZBX_DEV" = 'discovery' ]; then
iostat -d | \
tail -n +4 |
awk 'BEGIN {
ORS="";
print "{\"data\":["}
/\d/ {printf "%s{\"%s\":\"%s\"}", separator, "{#DEVICENAME}", $1, separator = ","}
END {print "]}" }'
exit 0
fi
# Test iostat log
[[ ! -f "${IOSTAT_LOG}" ]] && echo "[m|ZBX_NOTSUPPORTED] [No such file ${IOSTAT_LOG}]" && exit 1
# Parse iostat file
function parse_iostat() {
grep ${ZBX_DEV} ${IOSTAT_LOG} | \
tr ',' '.' | \
awk -v field="$1" '
{sum+=$field; n++;}
END {if (n > 0) print sum/n;
else {print "[m|ZBX_NOTSUPPORTED] [Nodata.]" > "/dev/stderr"; exit 1};}'
}
# Exec parse funcion with number of column

esac
添加脚本执行权限
# chmod +x /usr/local/zabbix-agent/scripts/zabbix-iostat.sh
# 设置参数
# echo 'UserParameter=iostat[*],/usr/local/zabbix-agent/scripts/zabbix-iostat.sh "$1" "$2"' > /etc/zabbix/zabbix_agentd.d/iostat.conf
#重启zabbix_agentd
service zabbix-agent restart
# 测试自动发现
zabbix_agentd -t iostat[discovery]
3.加入crontab
# crontab -e
* * * * * ( sleep 10 && iostat -dxk 1 20 > /tmp/iostat.tmp && mv /tmp/iostat.tmp /tmp/iostat.log )
* * * * * ( sleep 40 && iostat -dxk 1 20 > /tmp/iostat.tmp && mv /tmp/iostat.tmp /tmp/iostat.log )
# 重启计划任务
/etc/init.d/crond restart
测试监控项
# zabbix_agentd -t iostat[vda,rkb/s]
iostat[vda,rkb/s] [t|0.007]

<description>Percentage of elapsed time during which I/O requests were issued to the device (bandwidth utilization for the device). Device saturation occurs when this value is close to 100% for devices serving requests serially. But for devices serving requests in parallel, such as RAID arrays and modern SSDs, this number does not reflect their performance limits.
对设备发出I/O请求的时间的百分比（设备带宽利用率）。设备饱和发生时，这个值是接近100%的设备服务请求连续。但在平行的服务请求的设备，如磁盘阵列和现代固态硬盘，这个数字并不反映其性能极限。</description>
