Most FusionReactor Log files can be easily imported into Excel (and other tools that can import delimited files) in order to analyze them or create graphs..
There are 4 major log files that you can import:
Make a copy of the log file you want to import. (It's better to work on copies than the live log files otherwise you may stop them from being written to)
Start Excel and from the [File] menu select [Open...] and then the log file. You may have to select Files of type: All files (*.*) to see the log files in the file picker
The Text Import Wizard dialog will appear
For the Original data type choose : Delimited and then press [Next >] at the bottom of the dialog
Select Space as the Delimiter and then press [Finish] at the bottom of the dialog
The Spreadsheet should now be filled with data in separate columns
Click on top of one or more columns that you wish to graph (to highlight the entire column) and then click on the small graph icon (Chart Wizard) in the toolbar (or from the menu [Insert]->[Chart]). Note you can find out what data the Excel columns contain by using the field number [letter] in the descriptions of the log files above.
Choose the graph style (e.g. line graph, scatter graph or bar graph) and then click finish.
Note: you can find out what data is stored in the columns using the descriptions of the log files above or by looking into the request-headers.txt, resource-headers.txt, jdbc-headers.txt or crashprotection-headers.txt files stored in the folder with the log files.
