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:
一、声音报警
二、电子邮件报警
三、手机短讯报警
      四、传真告警
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 88fly@163.com
注:iptables和selinux设置
2、配置nagios中报警邮箱
vi /usr/local/nagios/etc/objects/contacts.cfg
         define contact{
         contact_name                    mail                    ; Short name of user
         alias                           null             ; Full name of user
        service_notification_period     24x7 (和如下时间模版(timeperiod)保持一致)
         host_notification_period        24x7
         service_notification_options    w,u,c,r
         host_notification_options       d,u,r
         service_notification_commands   notify-service-by-email
         host_notification_commands      notify-host-by-email
         email                           88fly@163.com
         }
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:
define timeperiod{
        timeperiod_name 24x7
        alias           24 Hours A Day, 7 Days A Week
        sunday          00:00-24:00
        monday          00:00-24:00
        tuesday         00:00-24:00
        wednesday       00:00-24:00
        thursday        00:00-24:00
        friday          00:00-24:00
        saturday        00:00-24:00
        }
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-service-by-email' command definition
define command{
        command_name    notify-service-by-email
        command_line      echo " ** $NOTIFICATIONTYPE$ Service Alert: $HOSTNAME$/$HOSTADDRESS$ $SERVICEDESC$ is $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$ Additional Info:$SERVICEOUTPUT$ "| formail -I "Subject: $HOSTADDRESS$*$SERVICEOUTPUT$*$LONGDATETIME$"| sendmail -oi $CONTACTEMAIL$
        }

# '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 $HOSTSTATE$ **" $CONTACTEMAIL$
        }
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 
      进行破环性测试!
