Additional Info: PING WARNING - DUPLICATES FOUND! Packet loss = 0%, RTA = 1.61 ms Since I am new to Nagios and think that this is a great opensource platform which can do a lots of thing. But I just find something is not right for the ping result. Actually, this host is a Win2K3 Std server. I checked there is okay with the Windows Ping command. This is no duplicate ping packet found. So I am thinking about if this is the program bugs or this is because I run the Nagios server on a ESX platform which create problems. Please help! And many thanks.
