Nagios短信分组报警

Nagios监控对于服务器运维来讲是非常好的工具，可以监控各种操作系统的服务器，windows，linux,aix等等，还可以对路由器和交换机，打印机等网络设备进行监控，再结合邮件，短信,MSN等报警方式为系统管理人员节省了许多巡检时间而且成效显著！在我的运维环境中，随着监控客户端的增多，报警的频率也随着提高，没日没夜的收短信，最终不得不把手机短信调成震动模式。在收到的报警短信中，大部分是windows客户端异常的短信，相对而言，在服务器领域linux系统比windows系统稳定可靠的多。于是想到取消集中报警的方式，将windows报警发送到windows sa的手机上，linux报警发到自己的手机上，也就是分组短信报警。下面就来介绍下配置过程！

一:编辑command.cfg文件，添加fetion发送短信命令

[root@localhost ~]# vi /usr/local/nagios/etc/objects/commands.cfg
define command{
command_name notify-service-by-linux
command_line /usr/local/fx/fetion --mobile=1383838438 --pwd=123 --to=1383838438 --msg-utf8="主机：IP地址$HOSTADDRESS$，服务器描述： $HOSTALIAS$/$SERVICEDESC$ 目前状

态：$SERVICESTATE$ 信息摘要： $SERVICEOUTPUT$" --msg-type=1
}

define command{
command_name notify-service-by-windows
command_line /usr/local/fx/fetion --mobile=1383838438 --pwd=123 --to=1333333333 --msg-utf8="主机：IP地址$HOSTADDRESS$，服务器描述： $HOSTALIAS$/$SERVICEDESC$ 目前状

态：$SERVICESTATE$ 信息摘要： $SERVICEOUTPUT$" --msg-type=1
}

define command{
command_name notify-host-by-sms
command_line  /bin/echo null
}

二:编辑contacts.cfg文件，分别定义linux服务器的告警信息通过notify-service-by-linux发送，windows服务器的告警信息通过notify-service-by-windows，在本例中因为所有的服务器均禁止ping,所以所有的主机告警信息不发送！

[root@localhost ~]# grep -v '^#'  /usr/local/nagios/etc/objects/contacts.cfg
define contact{
contact_name                        linux
use                                 linux-contact
alias                               linux
service_notification_period         24x7
host_notification_period            24x7
service_notification_options        w,u,c,r,f,s
host_notification_options           d,u,r,f,s
service_notification_commands       notify-service-by-linux
host_notification_commands          notify-host-by-sms
}

define contact{
contact_name                       windows
use                                windows-contact
alias                              windows
service_notification_period        24x7
host_notification_period           24x7
service_notification_options       w,u,c,r,f,s
host_notification_options          d,u,r,f,s
service_notification_commands      notify-service-by-windows
host_notification_commands         notify-host-by-sms
}

define contactgroup{
contactgroup_name           linux
alias                       linux
members                     linux
}

define contactgroup{
contactgroup_name            windows
alias                        windows
members                      windows
}

三：编辑templates.cfg文件，在模板文件中分别定义linux服务器和windows服务器的各监控属性和通知类型(最重要的参数contact_groups)，最后用于监控客户端配置文件上

[root@localhost ~]# vi /usr/local/nagios/etc/objects/templates.cfg
define contact{
name                            linux-contact
service_notification_period     24x7
host_notification_period        24x7
service_notification_options    w,u,c,r,f,s
host_notification_options       d,u,r,f,s
service_notification_commands   notify-service-by-linux
host_notification_commands      notify-host-by-sms
register                        0
}

define contact{
name                            windows-contact
service_notification_period     24x7
host_notification_period        24x7
service_notification_options    w,u,c,r,f,s
host_notification_options       d,u,r,f,s
service_notification_commands   notify-service-by-windows
host_notification_commands      notify-host-by-sms
register                        0
}

define host{
name                            generic-host

retain_status_information       1
retain_nonstatus_information    1
notification_period             24x7
register                        0
}

define host{

use                             generic-host

notification_options            d,u,r
contact_groups                  linux
register                        0
}

define host{

notification_period             24x7
register                        0
}

四：linux客户端文件,host调用linux-server模板，service调用linux-service

[root@localhost ~]# grep -v '^#'  /usr/local/nagios/etc/objects/client/10.0.1.11.cfg
define host{
use                     linux-server            ; Name of host template to use
; This host definition will inherit all variables that are defined
; in (or inherited by) the linux-server host template definition.
host_name               10.0.1.11
alias                   10.0.1.11
address                 10.0.1.11
}

define service{
use                             linux-service         ; Name of service template to use
host_name                       10.0.1.11
service_description             CPU Load
check_command                   check_nrpe!check_load
}

五:windows客户端文件，host调用windows-server模板，service调用windows-service

[root@localhost ~]# grep -v '^#'  /usr/local/nagios/etc/objects/client/10.0.1.13.cfg
define host{
use             windows-server  ; Inherit default values from a template
host_name       10.0.1.13       ; The name we're giving to this host
alias           10.0.1.13       ; A longer name associated with the host
address         10.0.1.13       ; IP address of the host
}

define service{
use                     windows-service
host_name               10.0.1.13
service_description     NSClient++ Version
check_command           check_nt!CLIENTVERSION
notifications_enabled           1
}

六:重启nagios服务，并验证结果

[root@localhost ~]# service nagios reload
Running configuration check...done.
Reloading nagios configuration...done

后记：服务器报警信息固然重要，但如果报警信息泛滥，从应用或者资源上无法及时调整到位，运维人员难免会对报警短信产生厌烦情绪，进而可能会忽略重要的报警信息，对服务器运维造成负面的影响，也会让领导认为监控系统可有可无，其实还是可以从技术角度上解决一些问题的，例如工作时间短信发送到QQ邮箱，MSN上，非工作时间短信发送到运维人员手机或者值班手机上，就是一种不错的办法，但监控只是一种手段，服务器问题还是早预见早解决为妙！
