Good point - Ethereal is a tool for the same ecological niche as tools 
such as Network General's Sniffer, WildPackets' EtherPeek/AiroPeek/etc.,

Microsoft's Network Monitor, and so on.  It's a tool for capturing 
traffic, looking at packets in detail, and doing some statistical 
processing on a particular capture.

It's not an intrusion detection system, or a monitoring tool that looks 
for trends and provides alerts for them - it arguably both does too much

and too little for that ("too much" in the sense that it analyzes the 
packets in more detail than would be needed for those applications).  It

is not, and it is not intended to be, the be-all and end-all of network 
traffic capture and processing applications.
