本机测试！

[root@svr1 nrpe-2.12]# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

[root@svr1 nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H localhost -c check_load

OK - load average: 0.00, 0.00, 0.00|load1=0.000;15.000;30.000;0; load5=0.000;10.000;25.000;0;

load15=0.000;5.000;20.000;0;

备注：有时候在客户端本机上测试时，发现会报错。CHECK_NRPE: Error - Could not complete SSL handshake.

这个时候，注意下xinetd.d/nrpe 以及nrpe.conf 里关于allowed相关的选项，另外就是防火墙。

使用xinetd后发现重启xinetd并不能重启nrpe,只有将其 T掉然后再开。

从远程主机上测试下：

[root@svr4 ~]# /usr/local/nagios/libexec/check_nrpe -H 10.1.1.10 -c check_total_procs

PROCS CRITICAL: 249 processes
