Archiving Raw Data

Flow archive stores Raw Data files. These files can be analyzed in the Raw Data tab in Flow module. Archiving data is configured in Flow Settings > Configuration by setting:

• Temp folder - folder in which NetFlow Analyzer will temporary unpack Raw Data files

• Archived files folder - folder in which NetFlow Aggregator stores processed files

• Legacy raw files folder - folder in which NetFlow stores Raw Data files from previous versions
• Minimum free disc space - minimum free hard disk space is a value that needs to be free on the NetFLow Server in GB. Once saving of new Raw Data file threatens to lower free hard disk spaces bellow this value, NetFlow will delete the oldest Raw Data files freeing up the disk space. Default value is 30.00 GB.
• Minimum archive size in days - the system will warn you up to 7 days before archive space runs out

NetFlow Analyzer also warns you if your archive space is full and tells you exactly what actions are advised. Warnings are sent by email to NetVizura administrators and displayed when you log-in. Warning message is triggered when application concludes that Minimum free disc space will be reached before minimum amount of Raw Data files in days is stored (Minimum archive size in days).

Example of archive warning message for Minimum number of days set to 30 and Minimum disk space set to 2 GB:

10 more days of data (30 GB) still need to be stored, but only 7 more days' worth of space (21 GB) remains in the archive storage.

You need to provide more space for archive files. You can also move existing files to another location, or lower the minimum number of days (currently set to 30) for which you would like to keep the archive files. (30) days of archive files is approximately 90 GB.

Flow archive stores Raw Data files. These files can be analyzed in the Raw Data tab in Flow module. When the Flow archive is full, oldest Raw Date files will be deleted, although those Raw Data files would fall within configured minimum number of days.
