192.168.3.80－XSCF地址
192.168.2.80－solaris操作系统IP地址 (nagios客户端）
192.168.2.120－nagios服务器端
check_xscf.pl－检查xscf的执行脚本，放在nagios客户端上。
check_xscf.cfg－检查xscf的配置文件，主要用于设置温度和电压的阈值，放在nagios客户端上。
脚本下载地址：http://exchange.nagios.org/directory/Plugins/Uncategorized/Plugin-to-check-Sun%27s-XSCF-%28local-service%29/details
脚本执行方式：nagios服务器端通过check_nrpe调用nagios客户端上的check_xscf.pl脚本来执行xscf命令。

测试用户nagios是否能够通过identity_file在XSCF上执行命令 (192.168.2.80)
$ ssh -l mlc -i /usr/local/nagios/.ssh/id_rsa 192.168.3.80 showdomainstatus -a
The authenticity of host ‘192.168.3.80 (192.168.3.80)‘ can‘t be established.

第一次执行时先把xscf的地址加入到known_hosts里。

$ ssh -l mlc -i /usr/local/nagios/.ssh/id_rsa 192.168.3.80 showdomainstatus -a

把检查脚本check_xscf.pl和配置文件check_xscf.cfg拷贝到nagios客户端192.168.2.80的/usr/local/nagios/libexec目录下，并为check_xscf.pl文件增加执行权限
-bash-3.00# chmod a+x /usr/local/nagios/libexec/check_xscf.pl

在nagios客户端的/usr/local/nagios/etc/nrpe.cfg中增加:
command[check_xscf_hw]=/usr/local/nagios/libexec/check_xscf.pl -n 192.168.3.80 -u mlc -i /usr/local/nagios/.ssh/id_rsa -c showhardconf
command[check_xscf_ev]=/usr/local/nagios/libexec/check_xscf.pl -n 192.168.3.80 -u mlc -i /usr/local/nagios/.ssh/id_rsa -c showenvironment /usr/local/nagios/libexec
/check_xscf.cfg使用nagios试运行新加的两个检查

使用nagios用户试运行新加的两个检查项： 
-bash-3.00# su - nagios
