ZABBIX之磁盘IO监控

1，配置文件

cat /usr/local/zabbix/conf/zabbix_agentd/diskstats.conf

UserParameter=disk.discovery,python /usr/local/zabbix/bin/disk_discovery.py
UserParameter=diskstats[*],/usr/local/zabbix/bin/diskstats.sh $1 $2

2，DISK 自动发现脚本

cat /usr/local/zabbix/bin/disk_discovery.py

#!/usr/bin/env python
#This script is used to discovery disk on the server
import subprocess
import json
args="cat /proc/diskstats |grep -E ‘\ssd[a-z]\s|\sxvd[a-z]\s|\svd[a-z]\s‘|awk ‘{print $3}‘|sort|uniq 2>/dev/null"
t=subprocess.Popen(args,shell=True,stdout=subprocess.PIPE).communicate()[0]
disks=[]
for disk in t.split(‘\n‘):
    if len(disk) != 0:
      disks.append({‘{#DISK_NAME}‘:disk})
print json.dumps({‘data‘:disks},indent=4,separators=(‘,‘,‘:‘)) 

3，diskstats脚本

cat  /usr/local/zabbix/bin/diskstats.sh

#!/bin/sh
device=$1
item=$2
case $item in
        read.ops)
            cat /proc/diskstats |grep "\b\$device\b"| head -1 | awk ‘{print $4}‘
            ;;
        read.ms)
            cat /proc/diskstats |grep "\b\$device\b"| head -1 | awk ‘{print $7}‘
            ;;
        write.ops)
            cat /proc/diskstats |grep "\b\$device\b"| head -1 | awk ‘{print $8}‘
            ;;
        write.ms)
            cat /proc/diskstats |grep "\b\$device\b"| head -1 | awk ‘{print $11}‘
            ;;
        io.active)
            cat /proc/diskstats |grep "\b\$device\b"| head -1 | awk ‘{print $12}‘
            ;;
        io.ms)
            cat /proc/diskstats |grep "\b\$device\b"| head -1 | awk ‘{print $13}‘
            ;;
        read.sectors)
            cat /proc/diskstats |grep "\b\$device\b"| head -1 | awk ‘{print $6}‘
            ;;
        write.sectors)
            cat /proc/diskstats |grep "\b\$device\b"| head -1 | awk ‘{print $10}‘
            ;;
esac

4，配置权限

chmod +x  /usr/local/zabbix/bin/disk_discovery.py

chmod +x  /usr/local/zabbix/bin/diskstats.sh

5，重启

killall zabbix_agentd

/usr/local/zabbix/sbin/zabbix_agentd

ps uax|grep zabbix

6，导入模版

到zabbix模板上做链接
