Identifying Network Problems
Identifying Network Problems
There are a number of sources from which to obtain information to identify a network
problem. Many of these sources are the same as those used to verify normal system
operation.
When a network problem occurs, usually more than one problem is reported (for
example, the user might encounter a file-system error at the same time that an event
message is reported). You can organize network problems into a hierarchy of entities,
as shown in Figure 20-1. When you begin to identify a network problem, it is usually
best to determine commonalities between all the errors reported beginning with the
lowest layers.
This subsection contains examples that show how you can use these sources to
identify a problem:

User Complaints

Note. For more information on interpreting performance information produced by tools such
as Measure and ASAP, see the discussion of Measure in the Measure User’s Guide.
