    FireGen for Pix Log Analyzer
 
        How do I configure FireGen to analyze my logs?
        When I run a report on demand, everything works fine but when I schedule a report with the same settings, the reports arrive blank.
        All the reports I generate are blank while the logs seem to contain relevant information for the selected period of time. I also get an error saying: "Analyze has returned code: 1 (invalid). Error: ".
        My log files are very large. What is the limit for FireGen?
        Can I schedule FireGen to run more than once per day?

What is the role of the "Sample log" setting on the "Log profiles" tab?
 
The log configured as "sample log" in the profiles tab is used by FireGen to determine the location of the logs and the name convention used.

If the "Log file detection method" is set as "Based on file naming convention" the FireGen will attempt to extrapolate the log name for the analysis interval. For example if the sample log is named syslog-2005-07-01.log and the analysis interval is August 2, 2005 then FireGen should be able to determine that the log naming convention is syslog-yyyy-mm-dd.log and that the log that it has to analyze is syslog-2005-08-02.log. If FireGen is not able to determine a pattern in the log file name then it will analyze the log set as "sample log" for that profile.

If the "Log file detection method" is set as "Based on log entry timestamp", FireGen will open all the files in the location of the sample log (and all subdirectories) and test them if: 1) they are the same type of log as the sample log and 2) the first or the last log entry is within the selected analysis interval. This method is useful if the log files do not have a certain naming convention.
