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
- notifications_enabled 1
- event_handler_enabled 1
- flap_detection_enabled 1
- failure_prediction_enabled 1
- process_perf_data 1
- retain_status_information 1
- retain_nonstatus_information 1
- notification_period 24x7
- register 0
- }
- define host{
- name linux-server
- use generic-host
- check_period 24x7
- check_interval 5
- retry_interval 1
- max_check_attempts 10
- check_command check-host-alive
- notification_period 24x7
- notification_interval 120
- notification_options d,u,r
- contact_groups linux
- register 0
- }
- define host{
- name windows-server
- use generic-host
- check_period 24x7
- check_interval 5
- retry_interval 1
- max_check_attempts 10
- check_command check-host-alive
- #notification_period 24x7
- notification_interval 30
- notification_options d,u,r
- contact_groups windows
- register 0
- }
- define service{
- name linux-service
- active_checks_enabled 1
- passive_checks_enabled 1
- parallelize_check 1 problems)
- obsess_over_service 1
- check_freshness 0
- notifications_enabled 1
- event_handler_enabled 1
- flap_detection_enabled 1
- failure_prediction_enabled 1
- process_perf_data 1
- action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
- retain_status_information 1
- retain_nonstatus_information 1
- is_volatile 0
- check_period 24x7
- max_check_attempts 3
- normal_check_interval 1
- retry_check_interval 2
- contact_groups linux
- notification_options w,u,c,r
- notification_interval 1440
- notification_period 24x7
- register 0
- }
- define service{
- name windows-service
- active_checks_enabled 1
- passive_checks_enabled 1
- parallelize_check 1
- obsess_over_service 1
- check_freshness 0
- notifications_enabled 1
- event_handler_enabled 1
- flap_detection_enabled 1
- failure_prediction_enabled 1
- process_perf_data 1
- action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
- retain_status_information 1
- retain_nonstatus_information 1
- is_volatile 0
- check_period 24x7
- max_check_attempts 3
- normal_check_interval 1
- retry_check_interval 2
- contact_groups windows
- notification_options w,u,c,r
- notification_interval 1440
- 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！
