Problem with false status

If you want to use check_ping instead of check_fping then you can change
the check_ping command definition in the checkcommands.cfg file to:

# 'check_ping' command definition
define command{
 	command_name	check_ping
 	command_line	$USER1$/check_ping -H $HOSTADDRESS$ -w $ARG1$
 -c $ARG2$ -n $ARG3$
 	}

You should probably leave the check-host-alive command as it was upon
installation otherwise you will run into problems if you have more than
one host. The check-host-alive command should be as follows:

# 'check-host-alive' command definition
define command{
        command_name    check-host-alive
        command_line    $USER1$/check_ping -H $HOSTADDRESS$ -w
3000.0,80% -c 5000.0,100% -p 1
        }
If you set it the way that you changed it
# 'check-host-alive' command definition
define command{
         command_name    check_ping
         command_line    $USER1$/check_ping -H $jello -w 3000.0,80% -c 
5000.0,100% -p 1

Then it will only check the host jello. The -H $HOSTADDRESS$ is a string
that gets it's info from the ip address of the hosts.cfg file. For
example

You have a host called jello whose ip address is 192.168.1.1. In the
services.cfg file you specify that you want Nagios to do a check_ping on
the host jello. The services.cfg file then looks at the hosts.cfg file
to find the ipaddress for the host jello and inserts it into the
$HOSTADDRESS$ string. Now, if you have a jello2 host and want to do a
check_ping on it as well it will take that hosts ip address and insert
it into the $HOSTADDRESS$ string. If you change that string to $jello$
then the check_ping command will only ever check the host jello.

Is  there a way to tell it to use check_ping instead of check_fping?

I have made the first change and my checkcommands has the following:

# 'check-host-alive' command definition
define command{
         command_name    check_ping
         command_line    $USER1$/check_ping -H $jello -w 3000.0,80% -c 
5000.0,100% -p 1
#        command_line    $USER1$/check_ping -H $HOSTADDRESS$ -w 
3000.0,80% -c 5000.0,100% -p 1

I will check and see if they have an fping program for solaris 8 since 
this is what my program is running on.

Thanks
