8、riables 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 do

9、ne 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 -

10、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 stri

Same syntax as SERVICESTATE. COUNTER = Check any performance counter of Windows NT/2000. Request a -l parameters with the following

12、 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/200

13、0. 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 li

14、ne 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 192.168.1.1 -p 1248 -v INSTANCES -l Process 2、检查

15、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.cfg define command command_name check_nt command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v $ARG1$ $ARG2$ register 1 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - -
