Use the administrative console to enable tracing at a server's
startup. You can use trace to assist you in monitoring system performance
and diagnosing problems.
About this task
The diagnostic trace configuration settings for a server process
determines the initial trace state for a server process. The configuration
settings are read at server startup and used to configure the trace service.
You can also change many of the trace service properties or settings while
the server process is running.
Procedure
- Start the administrative console.
- Click Troubleshooting > Logging and
Tracing in the console navigation tree, then click Server > Diagnostic
Trace.
- Click Configuration.
- Select the Enable Log check box to enable trace, clear the
check box to disable trace.
- Select whether to direct trace output to either a file or an in-memory
circular buffer.
Note: Different components can produce different
amounts of trace output per entry. Naming and security tracing, for example,
produces a much higher trace output than Web container tracing. Consider the
type of data being collected when you configure your memory allocation and
output settings.
- If the in-memory circular buffer is selected for the trace output
set the size of the buffer, specified in thousands of entries. This
is the maximum number of entries that will be retained in the buffer at any
given time.
- If a file is selected for trace output, set the maximum size in
megabytes to which the file should be allowed to grow. When the
file reaches this size, the existing file will be closed, renamed, and a new
file with the original name reopened. The new name of the file will be based
upon the original name with a timestamp qualifier added to the name. In addition,
specify the number of history files to keep.
- Select the desired format for the generated trace.
- Save the changed configuration.
- To enter a trace string to set the trace specification to the desired
state:
- Click Troubleshooting > Logging and Tracing in the console
navigation tree.
- Select a server name.
- Click Change Log Level Details.
- If All Components has been enabled, you
might want to turn it off, and then enable specific components.
- Click a component or group name. For more information see Log level settings
If the
selected server is not running, you will not be able to see individual component
in graphic mode.
- Enter a trace string in the trace string box.
- Select Apply, then OK.
- Allow enough time for the nodes to synchronize, and then start
the server.
