check_http issue

[rg25]

I am running nagios 3.2.1 on debian squeeze. I am succesfully executing /usr/lib/nagios/plugins/check_http --ssl -H xxx.xxx.xx.xxx -I xxx.xxx.xx.xxx -N form machine that . However, when I used the same on the server, I get

HOST ALERT: ubsinventory;DOWN;HARD;1;PING CRITICAL - Packet loss = 100%


template.cfg

define host{
name server ; The name of this host template
use generic-host ; Inherit default values from the generic-host template
check_period 24x7 ; By default, Windows servers are monitored round the clock
check_interval 5 ; Actively check the server every 5 minutes
retry_interval 1 ; Schedule host check retries at 1 minute intervals
max_check_attempts 10 ; Check each server 10 times (max)
check_command check-host-alive ; Default command to check if servers are "alive"

notification_interval 30 ; Resend notifications every 30 minutes
notification_options d,r ; Only send notifications for specific host states
contact_groups admins ; Notifications get sent to the admins by default
hostgroups servers ; Host groups that Windows servers should be a member of

}

server.cfg

define host{
use server ; Inherit default values from a template
host_name ubsinventory ; The name we're giving to this host
alias Inventory Lookup and FTP ; A longer name associated with the host
address xxx.xxx.xx.xxx ; IP address of the host
}

define hostgroup{
hostgroup_name servers ; The name of the hostgroup
alias Servers ; Long name of the group
}



define service{

Thanks in advance

This does not make much sense, in which case is this plugin working and in which case is it not? What is the difference?

I didn't mention the topology

iis server =============== sonicwall firewall ============ WAN =============== cisco firewall ================== debian squeeze running nagios

From debian squeeze's command line I am successfully executing /usr/lib/nagios/plugins/check_http --ssl -H xxx.xxx.xx.xxx -I xxx.xxx.xx.xxx -N

However, from the same machine, based on the configuration the same command is not successful. I looked at debug and it appears nagios3 is trying to ping the machine. I am not sure why as all I want to do is check_http.

sorry for the bother.

I figured out the problem. It appears that nagios check the status of a host by default by pinging it. After changing the check command everything is working.
