[comp.protocols.appletalk] AppleTalk/LocalTalk network monitoring/analysis tools

I am looking for information on the network analysis tools 
available for the macintosh and localtalk networks. 

I have found myself in charge of a moderate sized network that is 
having a few problems and am in need of tools that will allow
me to determine where the problems are. The network itself in
composed of 4 AppleShare servers and about 150 nodes on 5 zones.
Additionally, there are several K-boxes (3's and 4's), an 
InterBridge and other assorted devices. Obviously, the first step 
is to check out the cable plant (and this will be done), but I am 
reasonably certain that it is ok. 

Unfortunately, there is no historical information on this
network that will allow me to determine the cause & I have just
come into play on this. The symptoms that are reported are basically
just random crashes. As far as I can determine, the server crashes
do not always occur during peak load periods. The also occur when the
servers are idle. It has been reported that server crashes have 
occurred as often as every four hours although the servers have been
running now for anywhere between 10 and 100 days depending on which 
server you look at. I realize that 100days is quite acceptable, but
10 is not.

Also, is anyone aware of any limitations imposed by appleshare
on the number of files and directories on a volume. What effect
if any, is caused by using the full 32 characters for the file
name? I know that I am within the 'theoretical' limitations
stated by apple, but does anyone have experience with large 
servers and random crashes caused by this type of thing?

Any hints on what to look for or suggestions on diagnostic tools 
(as well as info about their capabilities) will be greatly appreciated.
