WebSphere Application Server logs
  • JVM logs: created by redirecting the System.out and
System.err streams of the JVM to independent log files.
One set of JVM logs for each application server and all of its
applications located by default in the following directory:
<profile_root>/<profile_name>/logs/<server_name>
  • Process logs: contain two output streams (stdout and stderror)
that are accessible to native code running in the process.
One set for each application server
  • IBM service log: contains both the WebSphere Application
Server messages that are written to the System.out stream
and some special messages that contain extended service
information that is normally not of interest, but can be
important when analyzing problems.
  • The HTTP server plug-in maintains a special log.

Log files: Types and locations
The destination and names for the log files are configurable.
The default location is: <was_root>\profiles\<profile_name>\logs\<server_name>

Log files:
SystemOut.log and SystemErr.log - Standard JVM output and error log
StartServer.log and stopServer.log
-Startup and shutdown of the Application Servers
activity.log - Events that show a history of activities
-Use AST Log and Trace Analyzer to read output from this file
trace.log – Output from diagnostic trace. Destination and name are configurable
http_plugin.log – Not in <was_root>
Location: <plugin_root>\logs\<webserver_name>
native_stdout.log and native_stderr.log
