Viewing debug traces for an execution unit (XU)

You can view execution unit (XU) execution traces to debug potential issues.

About this task

The execution unit (XU) debug trace (also called XU memory dump) is a stand-alone web page that represents a snapshot of the XU. It contains the XU settings, technical information about the caches, about the state of the current connection in memory, and about the XU configuration. It does not contain any messages that the XU writes to its log.

Attention:

The reset command resets the log in all the deployed execution units.

Procedure

  1. Click the Server Info tab.

    In the Server Info View, the execution unit table provides the number of warnings and errors logged on each server.

  2. Set the console log level to Debug.
    Note:

    The process is different on the zRule Execution Server for z/OS console for zRule Execution Server for z/OS: The XU memory dump link is available on the Server Info page. You do not need to click the name of the server to browse to another page.

  3. Click the name of the server in the list of deployed execution units.
  4. Click View in the Execution Unit Dump field to view the trace in a new browser window or click the Save icon. Save icon next to the View link to save the dump on your computer.

    The memory dump is downloaded as a .zip file. The default name of this file is infos.zip and it contains a single entry named infos.html, which is the XU dump in HTML format.
