Hi,

I am using nagios to moitor a remote host (20 miles away from the nagios
host & having a public IP). I have added that host in services.cfg for
ping test.

This is what the check command in services.cfg file for the host being
monitored.

check_command                   check_ping!100.0,50%!500.0,60%

Problem is:

When i ping (status is as shown below) it from terminal it gives echo
packets but nagios shows PING status CRITICAL.

I think there is problem with threshold value settings in the check
command. Does anybody can explain the check_ping!100.0,50%!500.0,60%
& the parameters specified in this check command.

in nagios event log i got following message.
SERVICE ALERT: Kharadi;PING;CRITICAL;HARD;3;PING CRITICAL - Packet loss
= 0%, RTA = 789.93 ms

Packet loss is zero but RTA is 789.93 what does it has to say?

> [root at pluto /]# ping 187.193.63.142
> PING 187.193.63.142 (187.193.63.142) 56(84) bytes of data.
> 64 bytes from 187.193.63.142: icmp_seq=0 ttl=54 time=695 ms
> 64 bytes from 187.193.63.142: icmp_seq=1 ttl=54 time=723 ms
> 64 bytes from 187.193.63.142: icmp_seq=2 ttl=54 time=741 ms

Above IP i mentioned is dummy for information security.
