NetFlow Tracker is an extremely powerful new
management tool from Crannog that provides a level of detail
previously unavailable in any application of its type. Using
Cisco's NetFlow technology (which is embedded in IOS in almost
all routers and chassis based switches), Tracker can instantly
profile all traffic going through the network and present a
detailed graphical view in increments as small as 1 minute.
The key
differences between NetFlow Monitor and NetFlow Tracker are:
Tracker
stores ALL NetFlow data so it will save a complete record of
all traffic that traverses your network for up to a week. After
that it can be archived off to a separate database for retrieval
as required.
Tracker
presents its data in 1 minute intervals, as opposed to 10 minutes
in Monitor.
Tracker
has no memory limitation so theoretically a single copy can
handle NetFlow data from an unlimited amount of devices.
Tracker
reports on packet as well as traffic levels so its extremely
useful from a SECURITY perspective for identifying 'rogue' devices,
devices infected with viruses or devices that may represent
a security breach.
