AS Names
This page lets you assign names to AS numbers appearing in reports. AS numbers below 34816 are assigned by several agencies; NetFlow Tracker comes with many of these ASs already named. Numbers between 34816 and 64511 are held by the IANA and should not be used. Numbers above 64511 are for private use and can be named using this page. You can assign or edit the name for a public or reserved AS by clicking “(more…)” in the title of the AS column.
Subnet Names
This page lets you assign names to the IP subnets that appear in reports. The network mask length appearing in a network report is the one used by the router to route the traffic described, so you may need to configure names for subnets that overlap.
Database Settings
This page lets you improve the performance of reports and charts, and change the number of days for which data is retained.
•Expect large result sets controls the method by which the database server manipulates raw data. If you have a fast disk subsystem you should set this to “Always” to ensure reports over large amounts of data perform well. If you have a slower disk subsystem, lots of RAM and a relatively small amount of data, you might consider setting this to “Never”, but bear in mind that reports over large amounts of data may take considerably longer to run.
•Maximum
•Sort buffer size is the size of the buffer used to reduce the amount of disk seeks when sorting rows for grouping or final display. Increasing this will improve reporting speed, but you are unlikely to see much improvement for sizes above 128MB.
•Hold back
•MySQL can not access temporary files should be unchecked to improve the performance of inserts database. However, it is possible that on Unix the user the NetFlow Tracker user runs as has a umask that creates temporary files that MySQL cannot read; in this case you must check this setting.
•Number of threads to use to generate a report controls the number of threads used to generate
