nagios配置邮件报警

1、配置sendmail

　　vi /etc/mail.rc

　　加入以下行

　　set bsdcompat

　　set from=邮件用户名@domain.com smtp=smtp.126.com set smtp-auth-user=邮件用户名 smtp-auth-password=邮箱密码 set smtp-auth=login

2、检查commands.cfg

# SAMPLE NOTIFICATION COMMANDS
#
# These are some example notification commands.  They may or may not work on
# your system without modification.  As an example, some systems will require 
# you to use "/usr/bin/mailx" instead of "/usr/bin/mail" in the commands below.
#
################################################################################


# 'notify-host-by-email' command definition
define command{
        command_name    notify-host-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****

Notification Type: $NOTIFICATIONTYPE$
Host: $HOSTNAME$
State: $HOSTSTATE$
Address: $HOSTADDRESS$
Info: $HOSTOUTPUT$

Date/Time: $LONGDATETIME$
" | /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 *****

Notification Type: $NOTIFICATIONTYPE$

Service: $SERVICEDESC$
Host: $HOSTALIAS$
Address: $HOSTADDRESS$
State: $SERVICESTATE$

Date/Time: $LONGDATETIME$

Additi
onal Info:

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

这是正确的命令配置，其中最重要的就是/bin/mail后边的命令配置

3、mqueue

ls /var/spool/mqueue

这个目录存储的是邮件发送队列，

如果这个里边满了不但会影响程序的运行，而且sendmail容易死掉，所以必要的时候要删除。

4、修改联系人地址

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

修改nagios@localhost为联系人的地址

5、检查所传送的电子邮件是否送出，或滞留在邮件服务器中

/usr/lib/sendmail -bp

若屏幕显示为“Mail queue is empty” 的信息，表示mail 已送出。

6、发送测试邮件

　 mail -s "test" luoyelin1989@126.com <content.txt

　　content.txt为邮件内容
