NetFlow Tracker

Installation

Minimum System Requirements

The type of system required to run NetFlow Tracker depends on the number of devices sending NetFlow information to it and the amount and nature of traffic handled by those devices. The following requirements are a guideline; the only way to determine your requirements is by testing the software’s performance in your network environment.

•Single processor of Pentium III, Pentium IV or Xeon class, although multiple processors will provide a modest performance increase.

•1GB RAM, although performance will increase with the amount of RAM available for the disk cache and database buffers.

•High performance disk subsystem with substantial free space – the exact nature of this is dependent on system load. For all but the lightest of loads, a server RAID card running RAID 5 over at least three high-performance disks is recommended. NetFlow Tracker stores and queries full information for a week; a busy enterprise router can generate in the order of 20GB of NetFlow information in this time.

Operating System Support

•Microsoft Windows￿ 2000 or above; server versions will provide better performance due to more advanced disk caching and memory management.

•Solaris￿ 8 or above (Intel￿-compatible or Sparc￿ processors).

•Any modern Linux distribution capable of running Java 1.4.2 and MySQL￿ 5.0 (Intel-compatible processors).

Pre-installation Checks

Before installing, there are a few things you need to check:

•NetFlow Tracker puts a heavy load on the system. It is strongly recommended that you install it on a dedicated server.

•You must be logged in as an administrator in order to install the software.

•NetFlow Tracker uses MySQL to provide database services. Due to the large database size and optimised structure, MySQL must be configured in a way that would seriously degrade the performance of many other types of software that use MySQL. Thus it is recommended that no other MySQL-dependent software be installed on the server running NetFlow Tracker.

•The version of MySQL used by NetFlow Tracker is significantly different to that used by Fluke Networks’ products NetFlow Monitor, NetWatch and ResponseWatch. If NetFlow Tracker is installed on a server running one of these products it will not function correctly. Likewise, if one of these products is installed on a server running NetFlow Tracker, both products are likely not to function correctly.
