16.2 Settings for acquiring the in-process HTTP server log
This section describes the items that can be set up for acquiring the in-process HTTP server log.
In the in-process HTTP server, the access log, trace based performance analysis, thread trace, and the communication trace are output for supporting the application development, for performance analysis at operation time, and for troubleshooting at failure detection time. For these files, you can change the number of files and the file size in the Easy Setup definition file.
The following table describes the settings that you can change for acquiring the in-process HTTP server log and parameters of the Easy Setup definition file corresponding to the items.
