Information about Monitoring EasyQoS
Cisco EasyQoS permits you to monitor an application's health on router WAN interfaces in your network for troubleshooting purposes. You view this data from the Monitoring window.
For this release, EasyQoS monitoring is provided as a beta functionality. The supported scale for this feature is 4000 managed devices including 400 monitored interfaces (200 routers with 2 interfaces each.)
The network devices are polled every 10 minutes to obtain the monitoring statistics.
The health of each application is measured as a sensitivity to packet loss on the router's WAN interface. This sensitivity is given a numerical value. The higher the sensitivity factor the more sensitive for packet loss (e.g. factor =5 => Excellent < 1%, factor = 100 => Excellent < 0.05%). The lower the sensitivity factor the less sensitive for packet loss.
Sensitivity to packet loss is different for each traffic class; for example, broadcast video is very sensitive to packet loss as compared to other applications. For this reason, each application (within a traffic class) has a different threshold.
You can view the sensitivity factor and thresholds for the traffic class in the Health Score Thresholds table. The Health Score Thresholds table is accessible from the Monitoring window by clicking the Edit Threshold button. This table displays how the default thresholds for the different traffic classes are defined. For each traffic class row there exists a range of values that is mapped to one of the Health Score Grades (Excellent, Good, Fair, Poor, Bad, Critical). The 0-100 percentage value (score) is calculated for each grade by linerly splitting the range into two parts and deciding upon the correct score.
You are able to reconfigure the sensitivity factor for each traffic class and therefore, each application. For information, see Changing Sensitivity Factor for the Traffic Class.
