Crannog NetFlow Tracker

NetFlow Tracker utilises the NetFlow export capabilities inherent in most Cisco routers, some Cisco switches and other manufacturers’ equipment to generate a number of unique databases. These databases are used to store information on all network sessions flowing through the network over an extended period of time. With this information, NetFlow Tracker can present valuable network usage reports that are suitable for a wide variety of audiences.

The NetFlow Tracker databases contain information on every single conversation traversing customer devices with a one minute resolution, over every interface in near-real time (up to the last two minutes).

By utilising NetFlow Tracker, it is now possible to provide complete network coverage from a data source that has already been installed and paid for the network routing hardware itself.

NetFlow Tracker makes conversation data accessible to a wide range of technical and non-technical audiences and integrates with any existing application that can be made to call a URL.

Key Features of NetFlow Tracker:

• Real-time database - every network flow recorded, per minute, up to the last minute
• Long-term databases - layered long-term historical reports in multiple time frames and time slices
• Extended reporting periods - The real-time data can be stored over extended periods of time (up to 14 days). The long-term database can be configured to store information for several years
• Secure integration with any third party management product, using URLs
• Ability to filter all reports based on any field stored in NetFlow record
• Reports can be tailored to suit specific audiences, e.g. real-time operations vs. capacity planning
• Utilises existing Cisco/other infrastructure; NetFlow Tracker is a software-only solution that requires no additional hardware probes

Key information stored by NetFlow Tracker:

• Source and destination IP address
• Source and destination TCP/User Datagram Protocol (UDP) ports
• Source and destination AS numbers
• Quality of service fields (ToS and Diff Serv)
• Packet and byte counts
• Input and output interface numbers
• Encapsulated protocol (TCP/UDP)
• Routing information (next-hop address, source Autonomous System (AS) number, destination AS number, source prefix mask, destination prefix mask)
