Using Performance Thresholds

</h1>
<a name="wp1277495"> </a><p class="pBody">
The Performance Manager Configuration Wizard allows you to set up two thresholds that will trigger 
events when the monitored traffic exceeds the percent utilization configured. These event triggers can be 
set as either Critical or Warning events that are reported on the DCNM-SAN web client Events browser 
page.

</p>
<a name="wp1277497"> </a><p class="pBody">
Absolute value thresholds apply directly to the statistics gathered. These statistics, as a percent of the 
total link capacity, are compared to the percent utilization configured for the threshold type. If the 
statistics exceed either configured threshold, an event is shown on the DCNM-SAN web client Events 
tab.

</p>
<a name="wp1277499"> </a><p class="pBody">
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% to 500%), where 100% equals the calculated weighted average. 

</p>
<a name="wp1287458"> </a><p class="pBody">
The threshold is set for Monday at 2 p.m. The baseline threshold is set at 130% 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).
