Hello, Before your answer , I decided to do a perl script which can do what I want for my job. But I like your idea and I try to modify the actual source code of check_ping I am a total Noob in C/C++ but I try to do this (based on check_ping nagios-plugins-1.4.13). It is sure Developers Masters in C/C++ will improve it. I add three options: -C for Critical Output Message -W for Warning Output Message -O for OK Output Message I do some tests with my modified plugin check_ping: Before: [root@localhost plugins]# ./check_ping -H <a href="http://127.0.0.1">127.0.0.1</a> -w 100.0,20% -c 500.0,60% -p 2 PING OK - Packet loss = 0%, RTA = 0.07 ms|rta=0.066000ms;100.000000;500.000000;0.000000 pl=0%;20;60;0 After: [root@localhost plugins]# ./check_ping -H <a href="http://127.0.0.1">127.0.0.1</a> -w 100.0,20% -c 500.0,60% -p 2 -O CUSTOM_MESSAGE_OK -C CUSTOM_MESSAGE_CRITICAL -W WARNING_MESSAGE CUSTOM_MESSAGE_OK|rta=0.103000ms;100.000000;500.000000;0.000000 pl=0%;20;60;0 Before: [root@localhost plugins]# ./check_ping -H <a href="http://128.0.0.1">128.0.0.1</a> -w 100.0,20% -c 500.0,60% -p 2 PING CRITICAL - Packet loss = 100%|rta=500.000000ms;100.000000;500.000000;0.000000 pl=100%;20;60;0 After: [root@localhost plugins]# ./check_ping -H <a href="http://128.0.0.1">128.0.0.1</a> -w 100.0,20% -c 500.0,60% -p 2 -O CUSTOM_MESSAGE_OK -C CUSTOM_MESSAGE_CRITICAL -W WARNING_MESSAGE CUSTOM_MESSAGE_CRITICAL|rta=500.000000ms;100.000000;500.000000;0.000000 pl=100%;20;60;0 Now for warning messages( tested with iptables which block some icmp packets..): [root@localhost plugins]# ./check_ping -H <a href="http://192.168.0.4">192.168.0.4</a> -w 100.0,20% -c 500.0,60% -p 10 -O CUSTOM_MESSAGE_OK -C CUSTOM_MESSAGE_CRITICAL -W WARNING_MESSAGE WARNING_MESSAGE|rta=1.212000ms;100.000000;500.000000;0.000000 pl=16%;20;60;0 I hope this script can help some of you. You can found the diff at the end of my email.
