An application log is a file containing information about how an application performed its work. The log consists of any number of entries, each marked with a particular severity (error, warning, information, etc.). The application log is stored as part of the transaction archive entry for the transaction that invoked the application.

An application makes entries in the application log by making subroutine calls that write information to the log. In addition, you must configure the Arbortext PE Request Manager to enable log entries (by default, no log entries are saved). You can do this for all applications, for all applications written in a particular programming language, or for individual applications. In each case, you can specify that only application log entries for a given severity and higher are saved, thereby controlling the amount of detail in the log. Refer to Configuration Guide for Arbortext Publishing Engine for information on how to configure these parameters.
