Problem with check_ping

Nagios Nagios Plugins support
1

Hi There,

I just installed nagios-3.0b5.tar.gz on a freshly installed Redhat Ent. 5 server and I’m experiencing some trouble with the check_ping plugin.

I keep on getting the following Error
<-----Error------>
Current Status: UNKNOWN (for 0d 4h 51m 40s)
Status Information: /bin/ping -n -U -w 10 -c 5 10.4.0.2
CRITICAL - Could not interpret output from ping command
</----Error----->

Here’s a copy the config I’m using.
<----Config----->
define host{
use generic-switch ; Inherit default values from a template
host_name AP1 ;The name we’re giving to this switch
alias AP1 Main ; A longer name associated with the switch
address 10.4.0.1 ; IP address of the switch
hostgroups switches ; Host groups this switch is associated with
}

define service{
use generic-service ; Inherit values from a template
host_name AP1 ; The name of the host the service is associated with
service_description PING ; The service description
check_command check_ping!200.0,20%!600.0,60% ; The command used to monitor the service
normal_check_interval 5 ; Check the service every 5 minutes under normal conditions
retry_check_interval 1 ; Re-check the service every minute until its final/hard state is determined
}

This is the first time I’ve installed Nagios so I’m most probably doing something wrong some where. Any ideas would be very welcome.

Thanks in advance.

Anyone?

in your service definition try changing the check_command line to read simply:

check_command check_ping

the arguments you have after the command should already be listed in the chec_ping command config.

I’m now getting the following error:
check_ping: %s: Warning threshold must be integer or percentage!

This is what the definition looks like in my commands.cfg file.

‘check_ping’ command definition

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

Thanks for the reply.

try this…

command_line $USER1$/check_icmp -H $HOSTADDRESS$ -w 100.0,60% -c 200.0,90% -p 5
