Planning for Network Growth

How the Network Performance Advisor Collects Data

10-21

Figure 10-12.

The data collector must examine your management station’s capabilities to

determine what is appropriate for the resource setting that you select. The

capabilities test begins when you click on the Apply Changes button. You will

see a screen listing some statistics about the test. Data collection will stop

during the test, and your management station may run slowly When the test

is complete (approximately four minutes), your resource settings will be in

effect.

Potential Problems with Data Collection

The existing historical traffic data becomes invalid when certain events occur,

for example:

■ When segments are split.

■ When a node is moved to another segment.

■ When you load a new topology file for a different network.

The Data Collector will reinitialize automatically after Discovery runs, in case

new devices or segments were discovered or devices were moved.

Data collection must take place for at least an hour before the Network

Planning report recommendations are valid. If changes to the network are

frequent, it will be difficult to accumulate a sufficient amount of traffic data

to generate accurate recommendations.
