nagios_自定義宏變量隱藏發送郵件賬號的敏感信息

需求：

Nagios在郵件告警的時候使用sendemail來發送郵件。

默認web管理界面下Configuration -->  Object Type: Commands -->

notify-host-by-email  notify-service-by-email 會顯示 發送郵件賬戶的登錄密碼

通過：nagios的宏變量來隱藏掉顯示出來的密碼（自定義宏變量）

vi /usr/local/nagios/etc/resource.cfg

加上

[email protected]
$USER3$=123456a

vi /usr/local/nagios/etc/objects/commands.cfg

修改$USER2$和$USER3$部分：

# '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 [email protected] -t "[email protected],[email protected],[email protected],[email protected],[email protected],
[email protected],[email protected],[email protected]" -s smtp.163.com -u "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" 
-xu $USER2$ -xp $USER3$
        }

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

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 [email protected] -t "[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected]" -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

效果如下：紅色箭頭黑色部分本顯示了發送郵件賬號的賬號以及密碼，現在可以通過上述通過nagios的自定義宏變量來隱藏相關的敏感信息。
