nagios_自定义宏变量隐藏发送邮件账号的敏感信息

34543

需求：
Nagios在邮件告警的时候使用sendemail来发送邮件。
默认web管理界面下Configuration -->  Object Type: Commands -->
notify-host-by-email  notify-service-by-email 会显示 发送邮件账户的登录密码

通过：nagios的宏变量来隐藏掉显示出来的密码（自定义宏变量）
vi /usr/local/nagios/etc/resource.cfg
加上

1 2	$USER2$=nmelot@163.com $USER3$=123456a

vi /usr/local/nagios/etc/objects/commands.cfg
修改$USER2$和$USER3$部分：

1 2 3 4 5 6 7 8 9 10

# 'notify-host-by-email' command definition 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 $HOSTSTATE$ **" $CONTACTEMAIL$         command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo : $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/bin/sendEmail -f XXX@163.com -t "XX@qq.com,XX@qq.com,XX@qq.com,XXX@qq.com,XX@qq.com, XX@qq.com,XXX@qq.com,XX@qq.com" -s smtp.163.com -u "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" -xu $USER2$ -xp $USER3$         }

# 'notify-service-by-email' command definition

1 2 3 4 5 6 7 8 9

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$SERVICEOUTPUT$" | /usr/bin/sendEmail -f XXX@163.com -t "XX@qq.com,XX@qq.com,XX@qq.com,XX@qq.com,XX@qq.com,XX@qq.com,XX@qq.com,XX4@qq.com" -s smtp.163.com -u  "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVI CEDESC$ is $SERVICESTATE$ **" -xu $USER2$ -xp $USER3$ #       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$SERVICEOUTPUT$" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAI
