在遠端：
[root@xxx ~]# /usr/local/nagios/libexec/check_nrpe -H 2.xx.xx.xx -c check_pingtest -a " -H 1.2.3.4 -w 150,30% -c 200,50% -p 5"
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.
近端查看日志發現：/var/log/message
Jun 5 07:41:31 xxx nrpe[10807]: Error: Request contained command arguments!
Jun 5 07:41:31 xxx nrpe[10807]: Client request was invalid, bailing out...
要做的是：
- 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
- 客戶端編輯 /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
- 服務端測試：[root@xxx ~]# /usr/local/nagios/libexec/check_nrpe -H 2.xx.xx.xx -c "check_pingtest" -a 1.2.3.4 10
- 測試ok 返回結果：PING OK - Packet loss = 0%, RTA = 53.43 ms|rta=53.426998ms;1500.000000;2000.000000;0.000000 pl=0%;100;100;0
Note：ping 結果可能不一樣 因為checkping 版本不一樣
