[vivek sharma sharma]

 Well now infact i am using check_ping only and with that the threshold entry in the command is :
>command_line    $USER1$/check_ping -H $HOSTADDRESS$ -w 450.0,20% -c 1200.0,95%
>
>
>Still in host status it shows as following::

>XXXX-XXXX  DOWN 03-14-2005 00:12:35 0d 3h 36m 48s PING CRITICAL - Packet loss = 0%, RTA = 774.70 ms

>here the host XXXX-XXXX is getting a loss of 0% and also the rta is only 774.70ms but still it is showing it as critical and also it shows the host down .
