    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

    Viewing logs
    • JVM logs:
    Click Troubleshooting > Logs and Trace in the administrative console navigation tree, or Navigate to the <profile_root>\<profile_name>\logs\<server_name> directory on the machine where logs are stored, and open SystemOut.log or SystemErr.log in a text editor
    • Process logs:
    Open <profile_root>\<profile_name>\logs\<server_name>\native_stderr.log
    or
    <profile_root>\<profile_name>\logs\native_stdout.log
    in a text editor
