搭建nagios的目的就是为了他的报警系统,nagios据我所了解可以有三种报警:
- 声音报警
- 电子邮件报警
- 手机短讯报警
下面是我的邮件报警的配置过程:
1、开启系统自带的sendmail邮件系统
service sendmail start
如果没有安装,可以yum一下
yum install -y sendmail* service sendmail restart
测试发送邮件:
> echo “test” | mail lihuipeng007@163.com
我系统在关掉iptables和selinux前提下是正常的
2、配置nagios中报警邮箱
vi /usr/local/nagios/etc/objects/contacts.cfg define contact{ contact_name nagiosadmin ; Short name of user use generic-contact ; Inherit default values from generic-contact template (defined above) alias Nagios Admin ; Full name of user email lihuipeng007@163.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ****** }
在email那里加上自己的邮箱,如果有多个可以用逗号隔开
3、设置报警方式:
vi /usr/local/nagios/etc/objects/templates.cfg define contact{ name generic-contact ; The name of this contact template service_notification_period 24×7 ; service notifications can be sent anytime host_notification_period 24×7 ; 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 register 0 ; DONT REGISTER THIS DEFINITION – ITS NOT A REAL CONTACT, JUST A TEMPLATE! }
这两个notify-service-by-email 和 notify-host-by-email 是在command.cfg那里定义的,看看是怎么定义的:
# ‘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$SERVICEOUTPUT$\n” | /bin/mail -s “** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **” $CONTACTEMAIL$ }
这里已经默认配置好,我们不用修改直接调用就是了
最后重启服务:
service nagios retart
然后随便关掉一些服务测试一下效果!很简单吧~
