Are my important applications performing well from a network perspective for my network users?
Has this been a persistent problem or is it getting worse?
If an application is not performing well, what might be causing the problem?
Access the report by going to
Monitor > Service Levels > Application Performance Score (APS)
.
A score between 0 and 10, where 0 is poor and 10 is excellent, indicates whether the app is performing well or poorly.
Scores are graphed over time to show how the scores changes and trends. The underlying metrics and measures used
to calculate scores are shown in the table below the graph. You can drill into the details of the APS by clicking an
application name.
Screenshot 80: The Application Performance Score displays scores from 0 - 10 over time.
A score includes input from one or more of the following metrics:
Network delay – the time taken for data to traverse the network (on the wire)
Server delay – the time taken for a server to respond to the request
Normalized network delay – the time taken for data to traverse the network, where the delay is measured inde-
pendent of the transaction size by assuming a normalized packet size of 1024 bytes
Normalized server delay – the time taken for a server to respond to the request, where the delay is measured inde-
pendently of the transaction size, by assuming a normalized packet size of 1024 bytes
Round-trip time – the time taken for
Jitter – the measure of variability of network delay, defined as one standard deviation of network delay
Inbound loss – the percentage of packet loss on inbound traffic
Outbound loss – the percentage of packet loss on outbound traffic
Each metric that contributes to the score has a threshold value set. The threshold may have been set manually or may
have been determined automatically by the Exinda Appliance observing the traffic for the period of time to determine a
