Log and trace settings

Use this page to view and configure logging and trace settings for the server.

支援的配置 支援的配置: You can only access this page when the server is configured to use basic log and trace mode.sptcfg
To view this administrative console page, click Troubleshooting > Logs and trace > server_name .
[z/OS]Note: You can configure tracing from the MVS™ console using the modify command.
Note: 這個主題參照一或多個應用程式伺服器日誌檔。 此外,在分散式和 IBM® i 系統上,另外也建議您可以配置伺服器來使用「高效能可延伸記載 (HPEL)」日誌和追蹤基礎架構,而不使用 SystemOut.logSystemErr.log, trace.logactivity.log 檔案。HPEL 與原生 z/OS® 記載機能也可以一起使用。如果您使用 HPEL,則可以從伺服器設定檔 bin 目錄,利用 LogViewer 指令行工具來存取您所有的日誌和追蹤資訊。請參閱有關利用 HPEL 疑難排解應用程式的資訊,以取得更多使用 HPEL 的相關資訊。

Switch to HPEL Mode

Use the Switch to HPEL Mode button to change the log and trace mode for the server to HPEL.

Note: Switching the server to HPEL log and trace mode requires a server restart.

Diagnostic Trace

The diagnostic trace configuration settings for a server process determine 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.

Java virtual machine (JVM) Logs

The JVM logs are created by redirecting the System.out and System.err streams of the JVM to independent log files. WebSphere Application Server writes formatted messages to the System.out stream. In addition, applications and other code can write to these streams using the print() and println() methods defined by the streams.

Process Logs

WebSphere Application Server processes contain two output streams that are accessible to native code running in the process. These streams are the stdout and stderr streams. Native code, including Java™ virtual machines (JVM), might write data to these process streams. In addition, JVM provided System.out and System.err streams can be configured to write their data to these streams also.

IBM Service Logs

The 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. There is one service log for all WebSphere Application Server JVMs on a node, including all application servers.

Change Log Level Details

Enter a log detail level that specifies the components, packages, or groups to trace. The log detail level string must conform to the specific grammar described in this topic. You can enter the log detail level string directly, or generate it using the graphical trace interface.

NCSA access and HTTP error logging

The NCSA access and HTTP error logging page enables you to configure the log settings for your HTTP server.

[z/OS]

Change log and trace mode

Specifies to switch between HPEL mode or Basic mode logging.

Note: Switching the server to HPEL log and trace mode requires a server restart.
