使用Zabbix监控Postfix-爱开源

使用Zabbix监控Mysql

使用Zabbix监控Postfix

操作系统：Centos 5.5 x86_64

Zabbix版本:1.8.1

1.安装pflogsumm
下载地址：http://jimsun.linxnet.com/postfix_contrib.html

perl -MCPAN -e “install Date::Calc”

tar xvf pflogsumm-1.1.3.tar.gz
cd pflogsumm-1.1.3
cp pflogsumm.pl /usr/local/bin/pflogsumm
chmod 755 /usr/local/bin/pflogsumm
cp pflogsumm.1 /usr/local/man/man1/pflogsumm.1
chmod 644 /usr/local/man/man1/pflogsumm.1

2.安装logtail
rpm包可以到这里下载:http://rpm.pbone.net/index.php3/stat/3/limit/2/srodzaj/1/dl/40/search/logtail/field%5B%5D/1/field%5B%5D/2

rpm -ivh http://mirrors.sohu.com/fedora-epel/5Server/x86_64/epel-release-5-4.noarch.rpm
yum -y install logcheck.noarch

3.zabbix客户端配置文件
最后增加：
UserParameter=postfix.mailq,mailq | grep -v “Mail queue is empty” | grep -c ‘^[0-9A-Z]’

4.建立一个脚本
# cat /usr/local/zabbix/sbin/zabbix-postfix.sh
#!/bin/bash
MAILLOG=/var/log/maillog
DAT1=/tmp/zabbix-postfix-offset.dat
DAT2=$(mktemp)
PFLOGSUMM=/usr/local/bin/pflogsumm
ZABBIX_CONF=/etc/zabbix/zabbix_agentd.conf
DEBUG=1

function zsend {
key=”postfix[`echo “$1″ | tr ‘ -‘ ‘_’ | tr ‘[A-Z]‘ ‘[a-z]‘ | tr -cd [a-z_]`]”
value=`grep -m 1 “$1” $DAT2 | awk ‘{print $1}’`
[ ${DEBUG} -ne 0 ] && echo “Send key “${key}” with value “${value}”” >&2
/usr/local/zabbix/bin/zabbix_sender -c $ZABBIX_CONF -k “${key}” -o “${value}” 2>&1 >/dev/null
}

/usr/sbin/logtail -f$MAILLOG -o$DAT1 | $PFLOGSUMM -h 0 -u 0 –bounce_detail=0 –deferral_detail=0 –reject_detail=0 –no_no_msg_size –smtpd_warning_detail=0 > $DAT2

zsend received
zsend delivered
zsend forwarded
zsend deferred
zsend bounced
zsend rejected
zsend held
zsend discarded
zsend “reject warnings”
zsend “bytes received”
zsend “bytes delivered”
zsend senders
zsend recipients

rm $DAT2

5.添加执行权限，并给zabbix用户授权
chmod +x /usr/local/zabbix/sbin/zabbix-postfix.sh

echo zabbix ALL = NOPASSWD: `which mailq` >> /etc/sudoers

6.添加一个计划任务
# crontab -e
#check postfix
*/30 * * * * /usr/local/zabbix/sbin/zabbix-postfix.sh

7.导入postfix_status模板
