The Log Server logs information about your Guided Search application to a log file. This file is later consumed by the Report Generator.

As soon as the Log Server starts, it attempts to open a log file and write a header and timestamp. If this fails, it exits immediately, without accepting any requests. The Log Server begins a new file when you issue the roll command, or automatically if the current file becomes larger than 1 GB.

The log file name is a combination of the current date and time and the log file prefix that you specify, in the format prefix.timestamp. You specify this when provisioning your Guided Search implementation. The timestamp indicates when the particular file was started and makes it possible to distinguish among multiple log files. When you provision a Log Server, you specify a path and prefix for its output.
