Nagios（七）——Nagios 郵件，短信告警

Nagios 除了監(jiān)控功能很強(qiáng)大之外，它的報(bào)警功能也很不錯(cuò)。從運(yùn)維的角度來(lái)講，報(bào)警一般就是郵件和短信報(bào)警這兩種方式，這次實(shí)驗(yàn)實(shí)現(xiàn)的是Nagios 的郵件報(bào)警功能。

1、安裝sendmail 組件

這里要確保sendmail 相關(guān)組件的完整安裝，

[root@server ~]# yum install sendmail* mailx

安裝完成后重啟sendmail 服務(wù)

[root@server ~]# service sendmail restart

Shutting down sendmail: [ OK ]

Starting sendmail: [ OK ]

Starting sm-client: [ OK ]

測(cè)試sendmail 發(fā)信情況

[root@server ~]# /bin/mail -s "`date +%Y-%m-%d` Server SMS Test" 159158*****@163.com

hello

admin

EOT

2、郵件報(bào)警的配置

一般而言，如果在整個(gè)系統(tǒng)中只有一個(gè)管理員，那么只需要在contact.cfg文件中，添加一下管理員的郵箱即可。但如果監(jiān)控的內(nèi)容中服務(wù)器有單獨(dú)的管理員，那就需要定義多個(gè)contact（聯(lián)系人），然后再通過(guò)contactgroup（聯(lián)系組）對(duì)各個(gè)contact 進(jìn)行分組。

(1) 修改contact.cfg

[root@server ~]# vim /usr/local/nagios/etc/objects/contacts.cfg

define contact{

contact_name nagios

use generic-contact

alias Nagios

email 159158*****@163.com，159158*****@139.com // 改為自己的郵箱地址即可

}

define contactgroup{

contactgroup_name admins

alias Nagios Administrators

members nagios

}

(2) 設(shè)置報(bào)警方式

[root@server ~]# vim /usr/local/nagios/etc/objects/templates.cfg

define contact{

name generic-contact ; The name of this contact template

service_notification_period 24x7 ; service notifications can be sent anytime

host_notification_period 24x7 ; host notifications can be sent anytime

service_notification_options w,u,c,r,f,s ; send notifications for all service states, flapping events, and scheduled downtime events

host_notification_options d,u,r,f,s ; send notifications for all host states, flapping events, and scheduled downtime events

service_notification_commands notify-service-by-email ; send service notifications via email

host_notification_commands notify-host-by-email ; send host notifications via email

}

(3) 修改commands.cfg

[root@server ~]# vim /usr/local/nagios/etc/objects/commands.cfg

# '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 $HOSTSTATE$ **" $CONTACTEMAIL$

}

# '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$SERVICEOUTPUT$" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$

}

看到這里已經(jīng)默認(rèn)配置好，我們不用修改直接調(diào)用就行了。

(4) 通過(guò)-v參數(shù)檢查配置無(wú)誤之后，重啟nagios

[root@server ~]# service nagios restart

Running configuration check...done.

Stopping nagios: .done.

Starting nagios: done.

(5) 郵箱設(shè)置

這里以139郵箱為例，設(shè)置收信

點(diǎn)擊左上角“設(shè)置”可以看到這個(gè)版塊
