解決：
被監控主機：
- 重新編譯安裝nrpe 帶這個參數 --enable-command-args ; make all ;make install #####allows clients to specify command arguments. *** THIS IS A SECURITY RISK! *** Read the SECURITY file before using this option!
- /usr/local/nagios/etc/nrpe.cfg ： dont_blame_nrpe=1 #打開參數傳遞
- 編輯 /usr/local/nagios/etc/nrpe.cfg : command[check_pingtest]=/usr/local/nagios/libexec/check_ping -H $ARG1$ -w 1500,100% -c 2000,100% -p $ARG2$ -t 10
