Nagios系统监控软件的邮件告警设置 推荐

七、邮件告警设置[/b]
nagios发警告邮件是采用本机的smtp服务,可以查看commands.cfg中关于发邮件的命令的定义,使用本机的mail命令,这就需要开启本机的smtp服务,为了安全可以在防火墙上设置拒绝其他的机器连本机的25号端口。

[align=left]1[/b]、查看command.cfg命令参数中邮件调用的情况：[/b][/align]
[align=left][root@localhost ]# vim /usr/local/nagios/etc/objects/command.cfg[/b][/align]
# 'notify-host-by-email' command definition （主机邮件告警设置）[/b]
define command{
command_name notify-host-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL[/b]$
}

# 'notify-service-by-email' command definition （服务邮件告警设置）[/b]
define command{
command_name notify-service-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL[/b]$
}

[align=left][root@localhost ]# vim /usr/local/nagios/etc/objects/contacts.cfg[/b][/align]
define contact{
contact_name nagiosadmin
use generic-contact
alias Nagios Admin
email test@139.com[/b] ([/b]这里设置接收告警的邮件地址[/b])[/b]
}

[align=left]3[/b]、打开并启动主控服务器的邮件发送服务：[/b][/align]
[root@localhost ]# service sendmail start[/b]
[root@localhost ]# chkconfig sendmail on[/b]

注意邮件发送服务SMTP[/b]协议需要打开本地的“25[/b]”端口，如果防火墙有阻挡的话，要开启起来。
