nagios

/usr/local/nagios/libexec/check_nrpe -H localhost
会返回当前NRPE的版本
[root@dbpi nrpe-2.8.1]# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.8.1

也就是在本地用check_nrpe连接nrpe daemon是正常的
注:为了后面工作的顺利进行,注意本地防火墙要打开5666能让外部的监控机访问

command_name check_nrpe
定义命令名称为check_nrpe,在services.cfg中要使用这个名称.
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
这是定义实际运行的插件程序.这个命令行的书写要完全按照check_nrpe这个命令的用法.不知道用法的就用check_nrpe –h查看

被控端需开放5666端口
