Baseline thresholds are defined for a configured time of day or week (1 day, 1 week, or 2 weeks). The
baseline is created by calculating the average of the statistical results for the configured time each day,
week, or every 2 weeks.
for a collection defined at 4 pm on a Wednesday.

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 2 weeks. Baseline thresholds are set as a percent of the average
(110% to 500%), where 100% equals the calculated average.
As an example, a collection is created at 4 pm on Wednesday, with baseline thresholds set for 1 week,
at 150% of the average (warning) and 200% of the average (critical). Performance Manager recalculates
the average for each link at 4 pm every Wednesday by taking the statistics gathered at that time each
Wednesday since the collection started. Using this as the new average, Performance Manager compares
each received traffic statistic against this value and sends a warning or critical event if the traffic on a
link exceeds this average by 150% or 200% respectively.

Set these thresholds on the last screen of the Collections Configuration Wizard by checking the Send
