By now you should be familiar with OpenView’s NNM and its supporting utilities. Even though many network administrators can get by with the basic OpenView information provided in this book, there is much more to learn. Configuring NNM with your own custom tools makes using it that much better.
While we can’t cover all the features of NNM in this appendix, we’ll discuss each of the following:
Using external data with xnmgraph
Inserting additional menu items into NNM’s menu
Creating NNM profiles for different users
Using NNM as a centralized communication device
Chapter 9 introduced
the xnmgraph command, but only touched on its
features. One particularly useful feature is the ability to graph
data from external sources. To see how you might graph external data,
first generate a graph of any type -- one of the graphs we created
in Chapter 9 will do -- and save the data to a
file. Then examine the contents of the file. Each output file
contains a short tutorial showing how to reshow the graph. Be sure to
$APP_DEFS/Xnmgraph, which contains
xnmgraph’s default settings.
Here’s a table we created by hand,
copying the format of a standard xnmgraph
datafile. The data points are organized into streams. A
stream is a set of data that will be plotted
as a single curve on the graph. All the streams in the file will be
combined into a single graph with multiple curves. The
StartTime is ignored. The
StopTime provides the value for ...
