Information About Performance Manager
Baseline thresholds create a threshold that adapts to the typical traffic pattern for each link for the same
time window each day, week, or every two weeks. Baseline thresholds are set as a percent of the average
(110 percent to 500 percent), where 100 percent equals the calculated weighted average. Figure 29-1
shows an example of setting a baseline threshold for a weekly or daily option.
Figure 29-1 Baseline Threshold Example
The threshold is set for Monday at 2 p.m. The baseline threshold is set at 130 percent of the average for
that statistic. The average is calculated from the statistics value that occurred at 2 p.m. on Monday, for
every prior Monday (for the weekly option) or the statistics value that occurred at 2 p.m. on each day,
for every prior day (for the daily option).
Flow Setup Wizards
The Performance Manager Flow and Performance Manager Setup wizards greatly simplify
configuration. You only need to select the categories of statistics to capture and the wizards provide a
list of flows and links to monitor. You can remove entries if desired, or just accept the provided list and
start data collection. Statistics for host and storage links are not associated with a specific port on a
switch, so you do not lose long term statistics if a connection is moved to a different port.
