11.1 Advanced Server Troubleshooting Tools
Advanced Server provides a variety of tools that can be used as troubleshooting aids.
These tools can be arranged into the following three categories:
● Tools used for assessing the status of the server.
● Tools used for automatic notification of the status of the server.
● Tools used for debugging specific server problems.
The following sections summarize the tools found in each category and briefly describe the
use of each in a troubleshooting context.
11.1.1 Tools for Assessing the Status of the Server
Advanced Server includes multiple tools that can be used to assess the operational status
of the server at any given time. As a server administrator, frequent assessment of server
status will improve your ability to notice a problem or trend quickly.
Periodic review of server status will provide a fairly stable basis for understanding how a
normal problem-free server appears. Over time, information that deviates from the norm will
be an indication that something has changed and warrants your attention.
Tools for assessing the status of the server include the following.
11.1.1.1 Event Viewer
A number of events related to the daily operation of the server can be tracked using Event
Viewer. These events are maintained in one of three event logs:
system, security , and appli-
cation . Administrators should develop and implement an event logging policy and include a
review of event logs as a regular part of troubleshooting activities.
Administrators will find it particularly useful to characterize the typical use of the server by
manipulating event log data using a spreadsheet or word processing program. This
approach can be used to generate a standard operating profile of the server and can be
used to predict trends in server usage.
For information about Event Viewer, see the “Concepts and Planning” manual .
Event logs also can be viewed using the elfread command. For more information,
type man elfread at the Advanced Server command prompt.
