NetFlow Tracker

IP Application Names

NetFlow Tracker receives application information in the form of a protocol number and port number. These correspond directly to specific network applications. Many are predefined (well-known ports) while others (registered ports) are defined by the software manufacturer. NetFlow Tracker comes configured with the well-known ports as well as many others. You can edit this list yourself with this page. By default, ports below 1024 are not shown on this page as they normally don’t need to be changed but, if required, these can be shown by clicking (more…) in the title of the Port column. A comprehensive list of all the well-known and registered ports is available at http://www.iana.org/assignments/port-numbers.

If an application uses multiple ports or a range of ports you can define it as a grouped application. Grouped applications appear as one entry in the application reports, regardless of context. You may find that a saved filter is more useful as a means of defining, for example, the traffic relating to a networked application running on a cluster of servers.

To define a grouped application you must first give it a unique identifier and a name; you can then add application ports and ranges of ports to it.

DiffServ Names

NetFlow Tracker can filter and report by differentiated service code point; you can assign names to each of the 64 code points here. The standard code point names are already configured.

Hostname Resolution Settings

This page lets you configure aspects of the resolution of hostnames for addresses encountered on reports. These are cached to increase reporting speed and reduce the amount of network traffic generated by the NetFlow Tracker when generating a report. You can change how long a resolved hostname is cached for, the default being 30 minutes, and how long a failure to resolve a hostname for a given address is remembered, the default being 10 seconds. You can also control the size of the cache and the number of threads used to resolve hostnames. If you find that hostname resolution is not working, click “Defaults” to put the settings back to useful default values. Click “Ok” to accept your changes or “Cancel” to abort.

Should you wish to clear the cache of resolved hostnames, disable resolution by clearing “Enable hostname resolution” and clicking “Ok”, then go back into the configuration page and enable resolution again by checking “Enable hostname resolution” and clicking “Ok”.
