So, in a generic sense, what I have is:
bizservice1 -> machine 1 -> machine 2
-> software 1 -> database 1
-> networking 1 -> router 1 -> switch 1 -> isp
etc.
There are about 2600 unique items. Some have 1 upstream relation and no
down stream. about 3 dozen or more at the top nodes of these "trees"
Some of the items, however, may have relationships across many of the trees
- some database servers are used in multiple applications, and some of the
branches listed "network" as an item for example, which we have discouraged
because the system that uses this data gets really slow when there are
massive cross overs, etc.
Anyways. as I mentioned up front, there are approx. 3400 relationships
between one node and another.
This makes visualization difficult.
At one point, we ran across some program that allowed us to remove nodes so
that we could remove from a particular session some of the noisier branches
or nodes (like network). Right now, I am working with zgrviewer. It is
nice. I need to learn move about it, so that I could, for instance, click
on a node and then ask it to move up the tree.
