• NRPE　參數的傳遞       

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：

1. 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!
2. /usr/local/nagios/etc/nrpe.cfg ：　dont_blame_nrpe=1　#打開參數傳遞
3. 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
4. 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 
5. 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
