Nagios监控Windows服务器（NSClient+安装与应用）1、 NSClient+安装1、 下载NSClient+插件点击下面链接下载/x-0.3.x/NSClient%2B%2B-0.3.9-Win32.msi2、 安装插件与配置1) 安装过程十分简单，直接点击下一步，下一步即可。安装过程注意如下图的设置即可2) 配置NSClient编辑NSClient安装目录下的NSC.ini文件，修改后，重启NSClient即可，如下图所示3) 模块作用说明，如下表ModuleDescriptionCommandsCheckSystem.dllHandles many system checksCPU, MEMORY, COUNTER etcCheckDisk.dllHandles Disk related checksUSEDDISKSPACEFileLogger.dllLogs errors to a file so you can see what is going onN/ANSClientListener.dllListens and responds to incoming requests from nagiosN/A2、 NSClient应用监控NSClient+与Nagios服务器通信，主要使用Nagios服务器的check_nt插件。原理图如下1、 check_nt插件的使用说明rootlocalhost libexec# ./check_nt -hcheck_nt v1.4.15 (nagios-plugins 1.4.15)Copyright (c) 2000 Yves Rubin ()Copyright (c) 2000-2007 Nagios Plugin Development Team This plugin collects data from the NSClient service running on aWindows NT/2000/XP/2003 server.Usage:check_nt -H host -v variable -p port -w warning -c critical-l params -d SHOWALL -u -t timeoutOptions: -h, -help Print detailed help screen -V, -version Print version informationOptions: -H, -hostname=HOST Name of the host to check -p, -port=INTEGER Optional port number (default: 1248) -s, -secret= Password needed for the request -w, -warning=INTEGER Threshold which will result in a warning status -c, -critical=INTEGER Threshold which will result in a critical status -t, -timeout=INTEGER Seconds before connection attempt times out (default: -l, -params= Parameters passed to specified check (see below) -d, -display=SHOWALL Display options (currently only SHOWALL works) -u, -unknown-timeout Return UNKNOWN on timeouts10) -h, -help Print this help screen -V, -version Print version information -v, -variable=STRING Variable to checkValid variables are: CLIENTVERSION = Get the NSClient version If -l is specified, will return warning if versions differ. CPULOAD = Average CPU load on last x minutes. Request a -l parameter with the following syntax: -l ,. should be less than 24*60. Thresholds are percentage and up to 10 requests can be done in one shot. ie: -l 60,90,95,120,90,95 UPTIME = Get the uptime of the machine. No specific parameters. No warning or critical threshold USEDDISKSPACE = Size and percentage of disk use. Request a -l parameter containing the drive letter only. Warning and critical thresholds can be specified with -w and -c. MEMUSE = Memory use. Warning and critical thresholds can be specified with -w and -c. SERVICESTATE = Check the state of one or several services. Request a -l parameters with the following syntax: -l ,. You can specify -d SHOWALL in case you want to see working services in the returned string. PROCSTATE = Check if one or several process are running. Same syntax as SERVICESTATE. COUNTER = Check any performance counter of Windows NT/2000. Request a -l parameters with the following syntax: -l counter, The parameter is optional and is given to a printf output command which requires a float parameter. If does not include %, it is used as a label. Some examples: Paging file usage is %.2f % %.f % paging file used. INSTANCES = Check any performance counter object of Windows NT/2000. Syntax: check_nt -H -p -v INSTANCES -l is a Windows Perfmon Counter object (eg. Process), if it is two words, it should be enclosed in quotes The returned results will be a comma-separated list of instances on the selected computer for that object. The purpose of this is to be run from command line to determine what instances are available for monitoring without having to log onto the Windows server to run Perfmon directly. It can also be used in scripts that automatically create Nagios service configuration files. Some examples: check_nt -H -p 1248 -v INSTANCES -l Process2、 检查Nagios目录下的libexec子目录，一定要存在check_nt（例如：/usr/local/nagios/libexec/check_nt）3、 查看Nagios服务器下定义check_nt命令rootlocalhost etc# vim commands.cfgdefine command command_name check_ntcommand_line $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v $ARG1$ $ARG2$register 14、 Windows系统监控应用首先定义一个需要监控的主机，本例为监控Winxp226，命令如下：define host host_name winxp226 alias My Windows Server address 26 use windows-server,host-pnp register 11) 监控 windows 主机的 CPU 负载define service host_name acs-1 service_description cpuload use generic-service check_command check_nt!CPULOAD!-l 5,70,80,10,80,90 register 1注：#CPU如果到达80%则报警，到达90%则警笛2) 监控 windows 主机的内存使用状况 define service host_name acs-1 service_description Memory Usage use generic-service check_command check_nt!MEMUSE!-w 80 -c 90 register 1注：内存使用到达80%则warn，到达90%则Critical3) 监控 windows 主机的开机运作时间define service host_name acs-1 service_description Uptime use generic-service check_command check_nt!UPTIME register 14) 检查windows主机是否已经安装了NSClient+，及它的版本号define service host_name acs-1 service_description NSClient+ Version use generic-service check_command check_nt!CLIENTVERSION register 15) 监控 windows 主机的 C: 的空间使用量define service host_name acs-1 service_description C: Drive Space use generic-service check_command check_nt!USEDDISKSPACE!-l c! -w 80 -c 90 register 16) 监控 windows主机的W3SVC设置的动作状况define service host_name acs-1 use generic-service service_description W3SVC check_command check_nt!SERVICESTATE!-d SHOWALL -l W3SVC 7) 监控 windows 主机的 Explorer.exe 进程运作状况，如程序终止，则会发 Criticaldefine service host_name acs-1 service_description Explorer use generic-service check_command check_nt!PROCSTATE! -d SHOWALL -l explorer.exe register 18) 监控 win
