zabbix_MegaCli监控raid及磁盘

客户端
1、安装MegaCli工具
MegaCli-8.07.10-1.noarch.rpm
使用rpm -ivh安装命令

rpm -i MegaCli-8.07.10-1.noarch.rpm

2、拷贝disk.conf文件到/etc/zabbix/zabbix_agent2.d 目录，disk.conf文件内容文字末尾附录
通过xftp上传即可

3、拷贝脚本diskcheck_megacli.sh到/opt下自定义目录，本次为/opt/externalscripts/
因目录权限问题，应先把配置文件跟脚本拷贝到当前登录用户home下，然后通过
sudo cp命令拷贝到对应目录

4、配置以管理员身份运行脚本命令
执行sudo visudo
在最后一行添加

zabbix ALL=(ALL)   NOPASSWD:/opt/externalscripts,/opt/MegaRAID/MegaCli/

修改/etc/zabbix/zabbix-agent2.conf文件，添加

Include=/etc/zabbix/zabbix_agentd.conf.d/

UnsafeUserParameters=1

5、配置zabbix环境变量（可能需要变更或修改，conf文件指定MegaCli64目录）
使用cat /etc/passwd查看zabbix用户目录，当前看到为/var/lib/zabbix，但实际目录并不存在
mkdir在对应目录创建zabbix目录并拷贝进入基本的配置文件
变更相应文件的所属主组

chown zabbix:zabbix .bashrc
chown zabbix:zabbix .bash_profile
chown -R zabbix:zabbix zabbix

6、重启agent2代理

sudo systemctl restart zabbix-agent2

7、zabbix给出的列出硬盘生成json的命令

MegaCli64 -PDlist -aAll -NoLog|grep Slot|awk 'BEGIN{printf "{\"data\":[\n\n"} {printf ",\n{ \"{#SLOT_NUM}\":\"%s\"}", $NF, $1;} END{ printf "\n\t]\n}\n";}' | sed '/^,$/d'

8、查看disk.conf中的监控项，测试

[krsc@node26 zabbix_agent2.d]$ zabbix_get -s node26 -p 10050 -k raid.pd.discovery

9、注意事项，监控项主要都依赖于自动发现，在zabbix系统中以配置，生效时间略长，约10-15分钟，无报错，查看下自动发现项是否发现成功即可

10、目前的监测标准
Medaia Error Count on Every Disk <=30

Other Error Count on Every Disk <=100

Predictive Failure Count On Every Disk <=2

Firmware State on Every Disk !=Unconfigured(bad),Failed

Raid Level State != Degrade

11、disk.cof文件内容

#硬盘自动发现  
UserParameter=raid.pd.discovery,sudo /opt/MegaRAID/MegaCli/MegaCli64 -PDlist -aAll -NoLog|grep Slot|awk 'BEGIN{printf "{\"data\":[\n\n"} {printf ",\n{ \"{#SLOT_NUM}\":\"%s\"}", $NF, $1;} END{ printf "\n\t]\n}\n";}' | sed '/^,$/d'
#收集Media Error Count
UserParameter=raid.phy.mec[*],sudo /opt/externalscripts/diskcheck_megacli.sh mec $1
#收集Other Error Count
UserParameter=raid.phy.oec[*],sudo /opt/externalscripts/diskcheck_megacli.sh oec $1
#收集Predictive Failure Count
UserParameter=raid.phy.pfc[*],sudo /opt/externalscripts/diskcheck_megacli.sh pfc $1
#检测硬盘状态，有故障则回复-1
UserParameter=raid.phy.firms[*],sudo /opt/externalscripts/diskcheck_megacli.sh firm $1
#检测阵列等级,有降级则回复-1
UserParameter=raid.level.state,sudo /opt/externalscripts/diskcheck_megacli.sh rdlevel

12、配置文件引用的diskcheck_megacli.sh脚本内容

#!/bin/bash
#zabbix监控硬盘信息脚本

. ~/.bash_profile > /dev/null

#获取磁盘信息
/opt/MegaRAID/MegaCli/MegaCli64 -PDlist -a0|grep -Ei '(Slot Number|Media Error Count|Other Error Count|Predictive Failure Count|Raw Size|Firmware state)'|sed -e "s:\[0x.*Sectors\]::g" >/tmp/pdinfo.txt

#将每块磁盘信息拆分，进行逐盘分析
split -l 6 -d /tmp/pdinfo.txt /tmp/pdinfo

#获取磁盘数量（实际数量=PDNUM+1）
PDNUM=`/opt/MegaRAID/MegaCli/MegaCli64 -PDGetNum -aAll|grep Physical|awk '{print $8}'`

#磁盘分块后文件名规范统一化
for((i=0;i<PDNUM;i++))
do
mv /tmp/pdinfo0$i /tmp/pdinfo$i >/dev/null 2>&1
#ls /tmp/pdinfo${i}
done
SLOT_NUM=$2
DATAFORMATE()
{
while read LINE
    do
        if [[ ${LINE} == Slot* ]];
            then
            SLOTNUMNAME=`echo ${LINE}|awk -F: '{ print $1 }'`
            SLOTNUM=`echo ${LINE}|awk -F: '{ print $2 }'`
        elif [[ ${LINE} == Media* ]];

            MEC=`echo ${LINE}|awk -F: '{ print $2 }'`
        elif  [[ ${LINE} == Other* ]];
            then
            OECNAME=`echo ${LINE}|awk -F: '{ print $1 }'`
            OEC=`echo ${LINE}|awk -F: '{ print $2 }'`
        elif  [[ ${LINE} == Predictive* ]];
            then
            PFCNAME=`echo ${LINE}|awk -F: '{ print $1 }'`
            PFC=`echo ${LINE}|awk -F: '{ print $2 }'`
        elif [[ ${LINE} == Raw* ]];
            then
            RAWNAME=`echo ${LINE}|awk -F: '{ print $1 }'`
            SIZE=`echo ${LINE}|awk -F: '{ print $2 }'`
        elif [[ ${LINE} == Firmware* ]];
            then
            FIRMWARENAME=`echo ${LINE}|awk -F: '{ print $1 }'`
            FIRMWARESTATUS=`echo ${LINE}|awk -F: '{ print $2 }'`
        fi
    done </tmp/pdinfo${SLOT_NUM}
}
