Nagios Ping Problem?



I am new in linux. Two days back I have installed Nagios on my linux (redhat) system and its working fine with other services but problem is only that i m getting following message on my mail and nagios web interface .

Host Status: DOWN (for 2d 17h 38m 2s)
Status Information: /bin/ping -n -U -w 10 -c 1
CRITICAL - Could not interpret output from ping command

My cgi.cfg file configuration -->

ping_syntax=/bin/ping -n -U -c 5 $HOSTADDRESS$

ANd My commands.cfg configuration —>

‘check_ping’ command definition

define command{
command_name check_ping
command_line $USER1$/check_ping -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 5

command_line $USER1$/check_ping -H $ARG1$ -w $ARG2$ -c $ARG3$ -p 5

command_line $USER1$/check_ping -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 1


Can anyone solve my problem and also let me know how can i change monitoring http service instead of ping and where i have to done changes.

Thanks in advance…

Well, the counter thats executed in the above command is 1… so it will send just an echo request, and will wait for just 1 echo reply

In the below command, its sending 5 echo requests, so it will wait for 5 echo requests.

Maybe you could try putting the same counter for each command.

Just guessing…
