The information collected by Sinefa Endpoint agents is used to formulate experience scores across the service delivery domains between the user and the application.
The overall user experience score for each user is the minimum score achieved across all service domains for that user. For example, if you have an Endpoint Score of 97, a Wi-Fi score of 90, a Local Network Score of 75 and an Internet Score of 66, the overall User Experience Score will be the minimum of the lot, being 66.
Each domain is scored out of 100 and a color is associated with each score:
|>80 - 100 Green|
|>60 - 80 Yellow|
|>40 - 60 Light Orange|
|>20 - 40 Dark Orange|
|0 - 20 Red|
Endpoint scores are calculated based on device resource usage, with a heavy weighting put on usage that typically impacts application performance the most.
- CPU Utilization - Low to moderate CPU utilization has minimal impact on the score. High CPU utilization will reduce the score moderately. Very high CPU utilization will reduce the score significantly.
- RAM Usage - Very high RAM usage will reduce the score moderately.
- Disk Usage - Only extremely high disk usage (e.g. disk almost full) will reduce the score moderately.
- Disk Queue Length - Low queue lengths have minimal impact on the score. High queue lengths will reduce the score moderately.
Wi-Fi scores are calculated based on the Wi-Fi connectivity metrics collected from the device, primarily the signal strength.
- Signal Strength - Has a very large impact on the overall Wi-Fi score, the score is almost entirely made up of the signal strength.
- TX/RX Rate - Has a small impact on the overall Wi-Fi score, low TX/RX rates will reduce the score slightly.
Local Network scores are calculated by pinging the default gateway once every 10 seconds and analysing the resulting delay, jitter and loss.
- Default Gateway Delay - Response time over a few msec will reduce the score moderately.
- Default Gateway Jitter - Jitter above one msec will reduce the score moderately.
- Default Gateway Loss - Any loss will reduce the score significantly.
Internet scores are calculated based on the results of all layer 3 synthetic tests conducted by the device. The resulting delay, jitter, loss and availability metrics for each test are converted into a Network Quality Score (NQS) also used in the Tests report.
Coming soon, application scores will be calculated based on the results of all layer 7 synthetic tests conducted by the device.
