The table in this section displays the following information for each active SaaS application category:
- —The name of the SaaS application category.
-
- —The uplink through which the SaaS application traffic has traversed.
- Measured WAN Wide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. QOE—The QoE score is based on the active probe and uplink application statistics. The Loss, Latency Latency is an expression of time that a data packet takes to travel from one designated point to another. Network latency can be measured by determining the round-trip time (RTT) for a packet of data to travel to a destination and back again., and Jitter values are in milliseconds.
- Observed LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. QOE—The QoE score is based on analyzing the LAN segment of the communication as downlink SaaS traffic traverses the gateway. The Loss and Round Trip Time (RTT) values are in milliseconds.
- Observed WAN QOE—The QoE score is based on observing the WAN segment of the communication as uplink SaaS traffic traverses the gateway.
The following actions are available:
- In the SaaS Express Details section, click
to customize the QoE threshold values. For more information about how to customize the QoE threshold, see Navigating to the SaaS Express Dashboard.
- To view the graphical representation of application performance, click
to expand the collapsible section.- For the selected application, the Service Provider label displays the best uplinks corresponding to the selected time on the time series graph. The data is updated every five minutes based on the loss, latency, jitter, and the chosen best uplink information received from the device. For example, if you have set the time range filter to three hours and you select the first hour on the time series graph, the uplink displayed is corresponding to the data received at that particular time from the device. Uplink names in green indicate that they are the best choice for the selected time on the time series graph.
The following indications are available:
- The yellow up arrow
corresponding to the uplink name indicates that there was a change (roam) in the uplink in the last five minutes. - The red doughnut
corresponding to the uplink name indicates that the uplink is down. - The red diamond
on the graph indicate that the server is unreachable. This is also indicated in the WAN Interface column as a red doughnut corresponding to the interface name.
- The yellow up arrow
- Hover over the graph to view the values at a particular time of the day or the day of the week and so on, depending on the selected time range. The maximum, minimum, and average scores for each parameter for the selected time range are displayed next to the Measured WAN QoE, Observed LAN QoE, and Observed WAN QoE graphs.
- For the selected application, the Service Provider label displays the best uplinks corresponding to the selected time on the time series graph. The data is updated every five minutes based on the loss, latency, jitter, and the chosen best uplink information received from the device. For example, if you have set the time range filter to three hours and you select the first hour on the time series graph, the uplink displayed is corresponding to the data received at that particular time from the device. Uplink names in green indicate that they are the best choice for the selected time on the time series graph.
- In the graphical representation, click + next to the Measured or Observed QoE to expand and view the Mean Opinion Score (MOS), Loss, Latency, and Jitter values. To collapse the graph, click -.
- Hover over the graph to view the values at a particular time of the day or the day of the week and so on, depending on the time range selected. The maximum, minimum, and average scores for each parameter for the selected time range are also displayed.
