Default Aggregation
Overview
Aggregation reduces the amount of memory and disk resources required
by Traffix
™
Manager by collating the data collected for many devices into
a single device. For example, in sites where there is a lot of Internet
traffic, some or all external devices can be aggregated together. This may
be the only way to limit the resource usage to an acceptable level. Use
the Aggregation dialog box to set up aggregation.
Once a definition has been specified and the Traffix Manager processes
and Map restarted, this only affects data collected from this point on, and
not data already collected.
This makes any data analysis for data which crosses an “aggregation
change” boundary hard to interpret. In this case, 3Com
®
recommends
that you start a new database. See
Appendix B
, “Database Management
Using Traffix Control Panel” for more information.
Default
Aggregation
Aggregation provides a solution to the problem of large numbers of
devices on your network, without forcing you to discard any devices. Any
loss of data prevents you from seeing a true picture of how your network
is being used. Aggregation works by grouping together related devices
and replacing them with a single aggregate device.
By default, all devices in the local DNS domain will be kept in detail, and it
is only those outside the local domain that can be aggregated. See
“Launching the Traffix Manager Client”
on
page 26
for more information
about local domains. You can specify an alternative aggregation policy.
