Debug mode is a special operation mode when the Debug Window window is open, and is designed for analyzing the progress of Intellect software operation and for prompt debugging in case errors occur. Log files are created in this mode—they are stored on the disk for a specific time period.

Enabling debug mode

By default, debug mode is disabled. To enable debug mode, do the following:

1. Close the Shut down Intellect software.
2. Start the Tweaki.exe utility (see the Starting and shutting-down the Tweaki.exe utility).
3. Select the Intellect node in the tree on the left side of the utility dialog box.
4. Change the parameter Debug Mode from None to Debug 1, Debug 2, Debug 3 or Debug 4 (see description of modes in The Settings panel of the Windows section).
5. Click the OK button.
6. Start the Start Intellect system.
   The Debug Windowwindow item will appear in the Intellect main control menu.
   
7. Select Debug Windowwindow in the main control menu to open the Debug window. The selected item will be marked with a tick.
   

To hide the Debug window, select the Debug Windowwindow item in the menu once more.

Configuring log file parameters

You can set log keeping parameters both on the Intellect setting panel in the Tweaki.exe utility (see The Settings panel of the Intellect section) and using some registry keys:

1. The Time of log keeping (hours) parameter means the same as DebugTime registry key. It specifies the number of hours for keeping log files. 48 hours by default.
   
2. The Maximum size (MB) parameter means the same as DebugSize registry key. It specifies the number of megabytes provided for log. 100 MB by default.
   
3. The DebugZipDays registry key enables the logs archiving in the .gz format and specifies the time period for their keeping. 2 days by default.
   

Log files are rewritten when the maximum of one of the parameters is reached.

When the Debug 4 debug mode is enabled, the video.run log file displays the most detailed information about the file system and memory usage of each camera every 10 seconds. To reduce the number of info lines,, displayed every 10 seconds, to 6 (this will reduce the size of the log file), it is necessary to add the StatusInfo=0 key.

An example of the displayed information if StatusInfo=1 or no key:

Example.

The Time of log keeping (hours) is 720 hours (1 month) and the Maximum size (MB) is 100 MB.  

One week later the size of log file is 100 MB. It starts being rewritten though the log is kept less than it was specified. 

And if DebugZipDays has the value equal to the time period in days to keep logs, then logs are not rewritten − they are archived in the *.gz format and are kept for so long as it was specified in DebugZipDays parameter.
