win server里使用nagios的插件:nrpe_nt
首先需要安装nrpe_nt.0.8b-bin.zip
使用nrpe_nt_plugins.zip安装,这个插件包非常好,很强大
关于怎么配置nrpe.cfg
 
要用nrpe_nt_plugins.zip里面的命令 必须配置nrpe.cfg文件
 
command[nt_check_disk_d]=C:\gx-nrpe_nt\nagios\bin\diskspace_nrpe_nt.exe d: 70 90
 
必须要改成你放置这个插件的目录
 
Nagios server
localhost里配置命令:
 
check_nrpe!nt_check_disk_c
 
define service{
        use                     generic-service
        host_name               yyx
        service_description     check_disk_nrpent
        check_command           check_nrpe!nt_check_disk_c
}
 
其中nt_check_disk_cwin server端的命令。
 
配置完以后老是报错说找不到“nt_check_disk_c”命令,百思不得其解。
 
突然想起每次在centos里改完命令都要重启nagios服务,于是在win server里重启nrpe_nt服务。果然问题迎刃而解。
 
重启nrpe_nt命令:
net stop nrpe_nt
net start nrpe_nt
 
 
[url]http://trac.nakednuns.org/[/url] 这网站相信的介绍的NSClient++ 及它的各种组建的用法,非常好。看了受益匪浅!
 
本来准备用nrpe_nt来解决这个问题的,看来这个网站才知道原来NSClient++同样博大精深。
 CheckFileSize这条命令就可以做
不过首先看到这条命令的例子
 
CheckFileSize ShowAll MaxWarn=1024M MaxCrit=4096M File:WIN=c:\WINDOWS\*.*
WARNING: WIN: 2G (2325339822B)|WIN=2325339822;1073741824;4294967296
define command {
  command_name CheckFileSize
  command_line check_nrpe -H $HOSTADDRESS$ -p 5666 -c CheckFileSize -a ShowAll MaxWarn=$ARG1$ MaxCrit=$ARG2$ File:$ARG3$=$ARG4$
}
check_command CheckFileSize!1024M!4096M!WIN!c:\WINDOWS\*.*
 
看完就觉得云里雾里了,“CheckFileSize ShowAll MaxWarn=1024M MaxCrit=4096M File:WIN=c:\WINDOWS\*.*”这条命令能在cmd里运行么?
 
define command {
  command_name CheckFileSize
  command_line check_nrpe -H $HOSTADDRESS$ -p 5666 -c CheckFileSize -a ShowAll MaxWarn=$ARG1$ MaxCrit=$ARG2$ File:$ARG4$=$ARG5$
}
NSClient++明明用得是12489端口,为什么这里监听的是nrpe5666端口呢?
 
带着这些问题,开始了大海捞针似的google.com之旅,终于找到了答案。
 
还是怪自己对NSClient了解的不深啊。
 
原来命令是要先进入 nsclient /test里来运行的。敲了命令果然有了返回值。
 
nsclient的配置问价Nsc.ini 里,就有nrpe的端口。
 
配置文件如下:

[NRPE Client Handlers]
check_other=-H 192.168.0.1 -p 5666 -c remote_command -a arguments
 
只要开放nrpe5666端口就好。
 
接着就是配置nagios server端了
 
首先定义命令
define command {
  command_name CheckFileSize
  command_line check_nrpe -H $HOSTADDRESS$ -p 5666 -c CheckFileSize -a ShowAll MaxWarn=$ARG1$ MaxCrit=$ARG2$ File:$ARG4$=$ARG5$
}
接着定义服务:
define service{
        use                     generic-service
        host_name               yyx
        service_description     checkfilesize
        check_command           checkfilesize!1024M!4096M!WIN!c:\WINDOWS\*.*
}
其中c:\WINDOWS\*.*,表示CWINDOWS目录下的所有文件。
 
Nagios server端输入 check_nrpe –H 192.168.2.221 –c CheckFileSize –a ShowAll MaxWarn=1024M MaxCrit=2048M File:WIN= c:\WINDOWS\*.*”,系统报错:”CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.”
 
当时就觉得奇怪怎么会监听不到数据呢?去win server端查看,5666端口是开的,也正在监听。经过反复查找,原来nrpe_nt插件正在运行,是它的5666端口在监听,而不是NSClient++的端口在监听。停掉nrpe_nt服务,问题解决!
Ok!一切大功告成!用这两种方法,基本上所有的监控win server的问题都能解决了。
