A. List of Snapshot Logs to Be Collected

This section describes the execution environment directories of the configuration software that are to be collected when you want to collect snapshot logs at the same time. Note that if you expand the collected ZIP file, the directories are extracted in the same directory configuration as that before collection.

When you collect all snapshot logs at the same time, the log files and definition files of the configuration software and libraries of a system built with the application server are collected. You can change the directory paths to be collected by editing the following files. For details about the settings for collecting the snapshot log, see the subsection 3.3.3 Settings for collecting snapshot logs (Systems for executing J2EE applications) or the subsection 3.3.4 Settings for collecting snapshot log (Systems for executing batch applications).

The following table describes the correspondence with the data required for troubleshooting and the snapshot log data type.
