Frequently Asked Questions

> Q. What is LogFactor5?

> A. LogFactor5 is a Swing based GUI that leverages the power of log4j to provide developers with a sophisticated, feature-rich, visual tool for managing log messages.

> Q. Do I need to know how to use log4j in order to use LogFactor5?

> A. Yes, the documentation for LogFactor5 assumes the user has some understanding of how log4j works. Note however that the LogFactor5 examples will run regardless of a user's log4j knowledge level.

> Q. What are the memory requirements for LogFactor5?

> A. The LogFactor5 logging console window uses around 13 MB of memory to run on a Windows OS. Our memory profiling has shown that with a logging message of 25 words in length, and a stack trace nested seven methods deep, every 1000 records displayed in the logging console uses about 6.5 MB of memory. For this reason, when you are setting the maximum number of log records to be shown, you should be careful that you have enough memory to display all of the records. The default maximum number of records that will be displayed is set to 5000 to minimize the possibility of running out of memory. We recommend that Windows users have at least 96 MB of RAM when using LogFactor5.
