Planning for Network Growth
When There Are No Recommendations
When There Are No Recommendations
If the Add and Upgrade Equipment Report determines that, based on the
historical data for the time period you specified, there are no advantageous
ways to optimize the network, the Summary section of the report states that
there are no recommendations for changes to your network configuration at
this time. If you think that your network may need performance improve-
ments, try selecting a more representative time period. Verify that your traffic
data has been collected for the minimum time period, or the recommendations
may not be valid.
Looking at the Top Conversations table may help you determine where the
network traffic is occurring so that you can anticipate future growth needs.
N o t e Adding devices that can sample data to high traffic segments that do not
already have them allows the Advisor to perform a more detailed analysis of
those segments.
Controlling Data Storage—
Administration
You can specify some criteria to control how much data is collected. Select
Traffic Data Collector Settings from the Performance button in the navigation
frame, then select the
Storage tab. Your current settings are displayed in the
Current Storage Status on Server area. The Historic Traffic Data collection area
displays the following choices:
■ Storing data up to a maximum number of days of data or a maximum
amount of data, whichever occurs first. The default is 31 days, up to 100
MB. You can click the
Default Values button to set these values.
■ Storing data up to a maximum amount of data (in Megabytes).
■ Stopping collection of historical traffic data for analysis by the Network
Performance Advisor.
