Understanding What QPM Monitors
Both historical and real-time QoS monitoring reports display the same types of 
QoS monitoring data. Each QoS monitoring report contains graphs of the 
following types of QoS monitoring data:
The amount of traffic that matched the policy’s filters (before QoS), the 
amount of matching traffic that was dropped by QoS, and the amount of 
matching traffic that was transmitted (after QoS).
This information provides a general view of the efficiency of queued traffic 
through an interface. For example, you can see how much traffic has been 
dropped, and whether, on average, the classes of traffic are using the 
bandwidth allocated to them efficiently.
See the following topics for more detailed information:
A breakdown of the traffic that matched each of the policy’s filters.
This information allows you to see how traffic within each class is distributed 
among its match statements.This enables you to analyze your traffic by 
application. For example, you can see if traffic from one application is using 
too much of the bandwidth allocated to its traffic class.
See the following topics for more detailed information:
The amount of traffic to which QoS actions were applied because of the 
policy’s QoS configuration, broken out by the following types of QoS 
features:
