自定义监控lvs

 1. 修改zabbix_agent配置文件添加以下内容，重启agent
        Include=/etc/zabbix/zabbix_agentd.d/

2. 在zabbix安装目录下的scripts目录下添加一下脚本
        cat lvs_discovery_ActConn.sh    ----监控lvs上的80端口连接数
        　　　　　#!/bin/bash
		#filename: lvs_discovery.sh
		#author:
		#MY_KEY=(` sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep 443 |grep  "$1"|awk '{print $2}'|awk -F ":" '{print $1}'`)
		MY_KEY=(` sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep  "$1"|awk '{print $2}'|awk -F"[ ]" 'NR<4{print $1}'`)
		#MY_KEY=(`sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep  "$1"|awk '{print $2}'|awk  '{print $1}' | sed -e 's/80/http/g' -e 's/443/https/g')
		length=${#MY_KEY[@]}
		printf "{\n"
		printf  '\t'"\"data\":["
		for ((i=0;i<$length;i++))
		do     
			printf '\n\t\t{'
			printf "\"{#IFNAME}\":\"${MY_KEY[$i]}\"}"
        if [ $i -lt $[$length-1] ];then
                printf ','
        fi
		done
		printf  "]}\n"

3. 在zabbix.agentd.d下面新建配置文件
        cat ../zabbix_agentd.d/lvs_ActConn.conf
        # monitor lvs status
	UserParameter=lvs.status.discovery,/etc/zabbix/scripts/lvs_discovery_ActConn.sh   -----lvs.status.discovery为自动发现的key值
	#UserParameter=lvs.status[*],sudo /sbin/ipvsadm -L -n | egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep "$1" | awk '$$5 > 0 {print $$5}'  ----grep "$1"为位置变量
	UserParameter=lvs.status[*],sudo /sbin/ipvsadm -L -n | egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep "$1" | awk '{print $$5}'   ----lvs.status[*],*为lvs_discovery_ActConn.sh脚本传过来的参数

4. 监控lvs443端口的连接数
        　　　　　#!/bin/bash
		#filename: lvs_discovery.sh
		#author:
		#MY_KEY=(` sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep 443 |grep  "$1"|awk '{print $2}'|awk -F ":" '{print $1}'`)
		MY_KEY=(` sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep  "$1"|awk '{print $2}'|awk -F"[ ]" 'NR>3{print $1}'`)
		#MY_KEY=(`sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep  "$1"|awk '{print $2}'|awk  '{print $1}' | sed -e 's/80/http/g' -e 's/443/https/g')
		length=${#MY_KEY[@]}
		printf "{\n"
		printf  '\t'"\"data\":["
		for ((i=0;i<$length;i++))
		do     
			printf '\n\t\t{'
			printf "\"{#IFNAME}\":\"${MY_KEY[$i]}\"}"
        if [ $i -lt $[$length-1] ];then
                printf ','
        fi
		done
		printf  "]}\n"
5. 新建监控lvs443端口连接数配置文件
        cat ../zabbix_agentd.d/lvs_ActConnPort443.conf
        # monitor lvs status
	UserParameter=lvs.status443.discovery,/etc/zabbix/scripts/lvs_discovery_ActConnPort443.sh
	#UserParameter=lvs.status[*],sudo /sbin/ipvsadm -L -n | egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep "$1" | awk '$$5 > 0 {print $$5}'
	UserParameter=lvs.status443[*],sudo /sbin/ipvsadm -L -n | egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep "$1" | awk '{print $$5}'

6. 新建监控lvs443端口流量和包
        cat lvs_discovery_ActConn80.sh
        	#!/bin/bash
		#filename: lvs_discovery.sh
		#author:
		#MY_KEY=(` sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep 443 |grep  "$1"|awk '{print $2}'|awk -F ":" '{print $1}'`)
		#MY_KEY=(` sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep  "$1"|awk '{print $2}'|awk -F"[ ]" 'NR<4{print $1}'`)
		MY_KEY=(`sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep  "$1"|awk '{print $2}'|awk  'NR<4{print $1}'`)
		length=${#MY_KEY[@]}
		printf "{\n"
		printf  '\t'"\"data\":["
		for ((i=0;i<$length;i++))
		do     
			printf '\n\t\t{'
			printf "\"{#IFNAME}\":\"${MY_KEY[$i]}\"}"
		if [ $i -lt $[$length-1] ];then
                printf ','
        fi
		done
		printf  "]}\n"

7. 新建监控lvs80端口的流量配置文件
        cat lvs_ActConn443.conf
    	# monitor lvs status
	UserParameter=lvs.status80.discovery,/etc/zabbix/scripts/lvs_discovery_ActConn80.sh
	#UserParameter=lvs.status[*],sudo /sbin/ipvsadm -L -n | egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep "$1" | awk '$$5 > 0 {print $$5}'
	#UserParameter=lvs.status[*],sudo /sbin/ipvsadm -L -n | egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep "$1" | awk '{print $$5}'
	UserParameter=lvs.CPS80[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | sed '1,3s/http/80/g'| grep "$1" |awk '{print $$3}'
	UserParameter=lvs.InPPS80[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | sed '1,3s/http/80/g' | grep "$1"| awk '{print $$4}'
	UserParameter=lvs.OutPPS80[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | sed '1,3s/http/80/g'| grep "$1" | awk '{print $$5}'
	UserParameter=lvs.InByte80[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | sed '1,3s/http/80/g'| grep "$1"  | awk '{print $$6}'
	#UserParameter=lvs.InByte[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | grep "$1" |grep 443 | awk '{print $$6}'
	UserParameter=lvs.OutByte80[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP'| sed '1,3s/http/80/g' | grep "$1" | awk '{print $$7}'

8. 新建监控lvs443端口流量
        cat  ../scripts/lvs_discovery_ActConnhttp.sh
        #!/bin/bash
	#filename: lvs_discovery.sh
	#author:
	#MY_KEY=(` sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep 443 |grep  "$1"|awk '{print $2}'|awk -F ":" '{print $1}'`)
	MY_KEY=(` sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep  "$1"|awk '{print $2}'|awk -F"[ ]" 'NR>3{print $1}' | sed 's/443/https/g'`)
	#MY_KEY=(`sudo /sbin/ipvsadm -L -n |egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep  "$1"|awk '{print $2}'|awk  '{print $1}' | sed -e 's/80/http/g' -e 's/443/https/g')
	length=${#MY_KEY[@]}
	printf "{\n"
	printf  '\t'"\"data\":["
	for ((i=0;i<$length;i++))
	do     
        printf '\n\t\t{'
        printf "\"{#IFNAME}\":\"${MY_KEY[$i]}\"}"
        if [ $i -lt $[$length-1] ];then
                printf ','
        fi
	done
	printf  "]}\n"
9. 新建监控lvs443端口流量配置文件
        # monitor lvs status
	UserParameter=lvs.stat.discovery,/etc/zabbix/scripts/lvs_discovery_ActConnhttp.sh
	#UserParameter=lvs.status[*],sudo /sbin/ipvsadm -L -n | egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep "$1" | awk '$$5 > 0 {print $$5}'
	#UserParameter=lvs.status[*],sudo /sbin/ipvsadm -L -n | egrep -v 'TCP|UDP|Virtual|LocalAddress|ActiveConn' | grep "$1" | awk '{print $$5}'
	UserParameter=lvs.CPS[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | grep "$1"  |awk '{print $$3}'
	UserParameter=lvs.InPPS[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | grep "$1"  | awk '{print $$4}'
	UserParameter=lvs.OutPPS[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | grep "$1"  | awk '{print $$5}'
	UserParameter=lvs.InByte[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | grep "$1" | awk '{print $$6}'
	#UserParameter=lvs.InByte[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | grep "$1" |grep 443 | awk '{print $$6}'
	UserParameter=lvs.OutByte[*],sudo /sbin/ipvsadm -L --rate | egrep -v 'IP|Port|TCP' | grep "$1"  | awk '{print $$7}'
监控脚本和配置文件有点乱，还来不及作修改，只需要在配置文件里面第二行UserParameter=lvs.stat.discovery,/etc/zabbix/scripts/lvs_discovery_ActConnhttp.sh与脚本名对上就OK.另外加红的部分每个配置文件必须不一样，这个是自动发现的key值.

10. 开始配置自动发现规则和key值
        https://pan.baidu.com/s/1Sn7LVTdtjZHQvbyHjvNrqg 密码：302i这个模版还是有点问题的，不适合我们公司这种两个端口的Lvs，我在上面做了修改，以及自己加的图形。
        先导入模版之后，创建主机，关联模版，进入主机，选择自动发现规则开始配置。
