来自：网络

1.说明在此演示nagios通过check_nt监控windows主机，需要在windows主机上安装NSClient++，下载地址：[ /nscp/downloads]nscp/downloads[/url]
2.安装NSClient++[ /uploads/img/201501/22175458_my9Y.png][ /uploads/img/201501/22175459_ii9h.png]

[/url][/url]
Allowed hosts：nagios server的ip地址
NSClient password：在此设置密码后，在使用check_nt获取主机信息时需要使用-s password指定密码 nagios培训

安装完成，启动服务。
NSClient++的配置文件：INSTALLDIR\NSC.ini

Usage:
check_nt -H host -v variable [-p port] [-w warning] [-c critical]
[-l params] [-d SHOWALL] [-u] [-t timeout]

Options:
-H, --hostname=HOST
nagios需要监控的主机ip
-p, --port=INTEGER
指定访问被监控主机的ip地址，默认为1248
-s, --secret=<password>
指定访问被监控主机需要的密码
-w, --warning=INTEGER
warning状态的阈值
-c, --critical=INTEGER
critical状态的阈值
-t, --timeout=INTEGER
Seconds before connection attempt times out (default: -l, --params=<parameters> nagios实施

Parameters passed to specified check (see below) -d, --display={SHOWALL}
Display options (currently only SHOWALL works) -u, --unknown-timeout
Return UNKNOWN on timeouts10)
-v, --variable=STRING
指定对被监控主机监测哪些指标

可以使用的监测指标:
CLIENTVERSION = 获取NSClient的版本
# ./check_nt -H 10.8.4.23 -p 12489 -v CLIENTVERSION NSClient++ 0.3.9.328 2011-08-16
如果使用-l <version>指定了一个版本，一旦版本不符，将会返回warning

CPULOAD =
  过去x分钟cpu平均负载
  -l语法:
  -l <minutes range>,<warning threshold>,<critical threshold>.
  <minute range> 要小于 24*60.
  阈值是百分比，而且10个请求可以1次完成
  ie: -l 60,90,95,120,90,95
# ./check_nt -H 10.8.4.23 -p 12489 -v CPULOAD -l 5,80,90 CPU Load 6% (5 min average) | '5 min avg Load'=6%;80;90;0;100
# ./check_nt -H 10.8.4.23 -p 12489 -v CPULOAD -l 5,80,90,20,85,95 CPU Load 7% (5 min average) 8% (20 min average) | '5 min avg Load'=7%;80;90;0;100 '20 min avg Load'=8%;85;95;0;100

UPTIME =
  获取主机的运行时间
  -l <unit>
  <unit> = seconds, minutes, hours, or days. (default: minutes)
  Thresholds will use the unit specified above.
# ./check_nt -H 10.8.4.23 -p 12489 -v UPTIME -l hours System Uptime - 7 day(s) 3 hour(s) 58 minute(s) |uptime=171
# ./check_nt -H 10.8.4.23 -p 12489 -v UPTIME -l days System Uptime - 7 day(s) 3 hour(s) 58 minute(s) |uptime=7

USEDDISKSPACE =
  硬盘大小及使用率.
  -l选项只指定盘符: -l C
  Warning and critical thresholds can be specified with -w and -c.                   监控软件

# ./check_nt -H 10.8.4.23 -p 12489 -w 80 -c 90 -v USEDDISKSPACE -l C C:\ - total: 58.26 Gb - used: 36.94 Gb (63%) - free 21.32 Gb (37%) | 'C:\ Used Space'=36.94Gb;46.61;52.43;0.00;58.26

MEMUSE =
  内存使用率.
  Warning and critical thresholds can be specified with -w and -c.
# ./check_nt -H 10.8.4.23 -p 12489 -w 80 -c 90 -v MEMUSE Memory usage: total:5186.80 MB - used: 3414.76 MB (66%) - free: 1772.04 MB (34%) | 'Memory usage'=3414.76MB;4149.44;4668.12;0.00;5186.80

SERVICESTATE =
  检查一个或多个服务的状态.
  Request a -l parameters with the following syntax:
  -l <service1>,<service2>,<service3>,...
  You can specify -d SHOWALL in case you want to see working services in the returned string.
# ./check_nt -H 10.8.4.23 -p 12489 -v SERVICESTATE -l Spooler Spooler: Stopped

PROCSTATE =
  Check if one or several process are running.
  # ./check_nt -H 10.8.4.23 -p 12489 -v PROCSTATE -l NSClient++.exe   OK: All processes are running.

INSTANCES =
  Some examples:
  check_nt -H 192.168.1.1 -p 1248 -v INSTANCES -l Process
