zabbix之lvs监控设置

三、Lvs的监控设置


1、目的
lvs负载均衡的各tcp和udp端口的连接数


2、简略实施步骤


zabbix的自定义脚本采集数据；
自定义模板文件
自定义screen显示
3、zabbix_agentd.conf配置增加

4、lvs-connection.sh脚本内容
#!/bin/bash
function b11_80 {
        sudo    ipvsadm -l -n | grep 192.168.10.11:80 |awk '{print $5+0}'
        }      


function b12_80 {
        sudo ipvsadm -l -n | grep 192.168.10.12:80 |awk '{print $5+0}'
        }      
function b31_40172 {
        sudo    ipvsadm -l -n | grep 192.168.10.31:40172 |awk '{print $5+0}'
        }


function b32_40172 {
        sudo ipvsadm -l -n | grep 192.168.10.32:40172 |awk '{print $5+0}'
        }   


function b31_40177 {
        sudo ipvsadm -l -n | grep 192.168.10.31:40177 |awk '{print $6+0}'
        }      


function b32_40177 {
        sudo ipvsadm -l -n | grep 192.168.10.32:40177 |awk '{print $6+0}'
        }      
function b31_40174 {
        sudo ipvsadm -l -n | grep 192.168.10.31:40174 |awk '{print $6+0}'
        }


function b32_40174 {
        sudo ipvsadm -l -n | grep 192.168.10.32:40174 |awk '{print $6+0}'
        }
function b31_40252 {
        sudo ipvsadm -l -n | grep 192.168.10.31:40252 |awk '{print $6+0}'
        }


function b32_40252 {
        sudo ipvsadm -l -n | grep 192.168.10.32:40252 |awk '{print $6+0}'
        }
function b31_40177 {
        sudo ipvsadm -l -n | grep 192.168.10.31:40177 |awk '{print $6+0}'
        }


function b32_40177 {
        sudo ipvsadm -l -n | grep 192.168.10.32:40177 |awk '{print $6+0}'
        }
# airtalk  tcp ports 4001-4003
function b191_4001 {
        sudo ipvsadm -l -n | grep 192.168.10.191:4001 |awk '{print $5+0}'
        }
function b192_4001 {
        sudo ipvsadm -l -n | grep 192.168.10.192:4001 |awk '{print $5+0}'
        }
function b31_4002 {
        sudo ipvsadm -l -n | grep 192.168.10.31:4002 |awk '{print $5+0}'
        }
function b32_4002 {
        sudo ipvsadm -l -n | grep 192.168.10.32:4002 |awk '{print $5+0}'
        }
function b191_4003 {
        sudo ipvsadm -l -n | grep 192.168.10.191:4003 |awk '{print $5+0}'
        }
function b192_4003 {
        sudo ipvsadm -l -n | grep 192.168.10.192:4003 |awk '{print $5+0}'
        }
# airtalk  tcp port 3012
function b195_3012 {
        sudo ipvsadm -l -n | grep 192.168.10.195:3012 |awk '{print $5+0}'
        }
function b196_3012 {
        sudo ipvsadm -l -n | grep 192.168.10.196:3012 |awk '{print $5+0}'
        }
# Run the requested function
$1


脚本调试过程中用到的命令如下
去掉无用的行
ipvsadm -l -n |tail -n +4 | grep "\-"


统计tcp总连接数，如果http增加或者减少需要相应调整
ipvsadm -l -n |tail -n +4 | grep "\-" | head -4 |awk '{sum=sum+$5}END{print sum}'
统计udp总连接数，调整同上
ipvsadm -l -n |tail -n +4 | grep "\-" | tail -n +4 |awk '{sum=sum+$6}END{print sum}'




5、zabbix server端设置


主要为lvs_status模版文件，screen已经定义在其中
