zabbix 监控 lvs ipvsadm

zabbix 监控lvs 我想像中比较好弄，但是实际中遇到了权限的问题。记下，供有需要的朋友参考。

一、环境说明

zabbix:2.0.6
ipvsadm:1.24
OS:CentOS 5.4 x86
dip:192.168.100.14
rip:192.168.100.22 
rip:192.168.100.24
rip:192.168.100.76
rip:192.168.100.101


二、新建脚本 

[root@lvs-master zabbix]# pwd
/etc/zabbix


[root@lvs-master zabbix]# cat lvs-status.sh
#!/bin/bash
# get lvs connection @2013/09/12 by v1
# author:lizonggang


function AllConn  {
        sudo    /sbin/ipvsadm -L -n |awk '{print $5}'| awk 'BEGIN{sum=0}{sum+=$1}END{print sum}'
}
function 101Conn  {
        sudo    /sbin/ipvsadm -L -n | grep 100.101|awk '{print $5}'
}
function 22Conn  {
        sudo    /sbin/ipvsadm -L -n | grep 100.22|awk '{print $5}'
}
function 24Conn  {
        sudo    /sbin/ipvsadm -L -n | grep 100.24|awk '{print $5}'
}
function 76Conn  {
        sudo    /sbin/ipvsadm -L -n | grep 100.76|awk '{print $5}'
}

function AllInConn  {
        sudo    /sbin/ipvsadm -L -n |awk '{print $6}'| awk 'BEGIN{sum=0}{sum+=$1}END{print sum}'
}
function 101InConn  {
        sudo    /sbin/ipvsadm -L -n | grep 100.101|awk '{print $6}'
}
function 22InConn  {
        sudo    /sbin/ipvsadm -L -n | grep 100.22|awk '{print $6}'
}
function 24InConn  {
        sudo    /sbin/ipvsadm -L -n | grep 100.24|awk '{print $6}'
}
function 76InConn  {
        sudo    /sbin/ipvsadm -L -n | grep 100.76|awk '{print $6}'
}


# Run the requested function
$1

三、修改配置文件

zabbix agent 添加如下,并重启agent.
[root@lvs-master zabbix]# vim zabbix_agentd.conf
### ipvsadm Active
UserParameter=lvs.AllConn[*],/etc/zabbix/lvs-status.sh AllConn
UserParameter=lvs.101Conn[*],/etc/zabbix/lvs-status.sh 101Conn
UserParameter=lvs.22Conn,/etc/zabbix/lvs-status.sh 22Conn
UserParameter=lvs.24Conn,/etc/zabbix/lvs-status.sh 24Conn
UserParameter=lvs.76Conn,/etc/zabbix/lvs-status.sh 76Conn
### ipvsadm InActive
UserParameter=lvs.AllInConn,/etc/zabbix/lvs-status.sh AllInConn
UserParameter=lvs.101InConn,/etc/zabbix/lvs-status.sh 101InConn
UserParameter=lvs.22InConn,/etc/zabbix/lvs-status.sh 22InConn
UserParameter=lvs.24InConn,/etc/zabbix/lvs-status.sh 24InConn
UserParameter=lvs.76InConn,/etc/zabbix/lvs-status.sh 76InConn

[root@lvs-master zabbix]# chmod +x lvs-status.sh

四、排错

由于之前lvs-status.sh 脚本没有加入sudo ,所以看agent日志报如下：

[root@lvs-master zabbix]# tail -f /tmp/zabbix_agentd.log 
Can't initialize ipvs: Permission denied (you must be root)
Are you sure that IP Virtual Server is built in the kernel or as module?


但是加入sudo 又报如下：

sudo: sorry, you must have a tty to run sudo


最终解决办法是visudo 修改如下：

[root@lvs-master ~]# visudo
#Defaults    requiretty

添加
zabbix  ALL=(ALL) NOPASSWD:/sbin/ipvsadm

问题是解决了，但是不知道#Defaults    requiretty 这样会不会有其它的问题？？


五、zabbix server 测试

[root@jumper ~]# zabbix_get -s 192.168.100.14 -p 10050 -k "lvs.AllConn"
2326

六、导入模板(请根据自己的需要，添加/修改/删除)

<?xml version="1.0" encoding="UTF-8"?>
