使用Zabbix通过ILO管理口监控惠普服务器
壤驷骁
概述
本文的环境：Zabbix版本为3.4，一台Server，一台Porxy，一台agent。Porxy主动抓取agent的状态并sender到Server。
首先需要保证服务器的ILO口能够联网，并且拥有管理用户和密码，Proxy和Agent能够保持联网。本文只针对HP系列服务器，其他品牌服务器后续更新。
安装
首先安装所需的软件包
yum install perl-IO-Socket-SSL.noarch perl-XML-Simple.noarch perl-Class-Accessor perl-Config-Tiny.noarch perl-Monitoring-Pluginrpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
脚本的代码我贴在文末，脚本存放在/root下，无需修改其内容，文件名保存为hp.pl，权限保持为-rw-r--r-- 即可。
perl /root/hp.pl -u Admin -p aliyun -3 -v -t 60 -H 192.168.1.1脚本参数介绍：
-u：服务器ILO管理口的用户名
-p：服务器ILO管理口的密码
-3 -V：ILO版本
-t：超时时间
-H：主机地址
返回以下内容：（截取部分风扇）
<ZONE VALUE = "System"/>
<LABEL VALUE = "Fan 1"/>
<STATUS VALUE = "Not Installed"/>
<SPEED VALUE = "0" UNIT="Percentage"/>
</FAN>
<FAN>
<ZONE VALUE = "System"/>
<LABEL VALUE = "Fan 2"/>
<STATUS VALUE = "Not Installed"/>
chunk: 1ff
chunk size: 511
<SPEED VALUE = "0" UNIT="Percentage"/>
</FAN>
<FAN>
<ZONE VALUE = "System"/>
<LABEL VALUE = "Fan 3"/>
<STATUS VALUE = "OK"/>
<SPEED VALUE = "27" UNIT="Percentage"/>
</FAN>
<FAN>
<ZONE VALUE = "System"/>
<LABEL VALUE = "Fan 4"/>这里可以看到，可以抓取到风扇的序号和运行状态，当前状态为“Not Installed”和“OK”，我们可以通过grep和awk进行过滤，筛选需要的信息。
这时可以写一个脚本，脚本内容如下：
#!/bin/bash
LSI_LOG=/tmp/hp.log
perl /root/check_ilo2_health.pl -u administrator -p aliyun -3 -v -t 60 -H 192.168.1.1 >$LSI_LOG
cat $LSI_LOG | grep -v "^chunk" |grep -A 2 "Fan [1-9]" |grep "STATUS VALUE" |sed -e 's/"/ /g' | awk -F "/" '{print $1}' | awk -F "=" '{print $2}' 得到以下内容
Not Installed
Not Installed
OK
OK
Not Installed
OK
OK
OK 这时就可以写一个循环，将其推送到server上，代码如下：
Sender的用法：
-z 主机IP
-s Zabbix上的主机名
-k Zabbix监控项的Key值
-o 数值，key值的数值
#!/bin/bash
LSI_LOG="/tmp/hp.log"
perl /root/hp.pl -u Administrator -p ****** -3 -v -t 60 -H 192.168.1.11 >$LSI_LOG
#get Fan state
n=1
s=1
cat $LSI_LOG | grep -v "^chunk" |grep -A 2 "Fan [1-9]" |grep "STATUS VALUE" |sed -e 's/"/ /g' | awk -F "/" '{print $1}' | awk -F "=" '{print $2}' > $LSI_LOG.temp
while read line
do
/usr/bin/zabbix_sender -z 192.168.1.10 -s hp01 -k fan"$n".state -o "$line"
((n++))
if [ $n == 13 ];then
n=1
fi
done <$LSI_LOG.temp脚本保存在/usr/lib/zabbix/externalscripts/hp.sh
创建定时任务，crontab -e ，每五分钟执行一次
*/5 * * * * /usr/lib/zabbix/externalscripts/hp.sh >/dev/null 2>&1
此时在Zabbix添加相应的监控项以及Key值就可以了，需要注意的是，脚本Sender的-s参数(主机名字)一定要和Zabbix的主机名字对应，否则将无法获取数据。
然后创建相应触发器即可。
