What is the Performance Insights Dashboard?
Performance Insights Dashboard is a part of the Intelligent Edge Dashboards group. It intents to answer the performance questions on a given flow.
What are the TCP applications the site is accessing by displaying all the Appflows?
For each flow, who is the initiator and to what application?
What is the start time and end time?
How much data is transferred for this flow?
What is the user experience for any specific flow, is there any performance degradation for the flow? Specifically, performance degradation comes from network packet loss, client side congestion, server side congestion or slow application.
were there packet loss? If so, did the packet loss occur on the network between the client machines and the Bumblebee CPE device (Client-CPE segment), or on the network between the Bumblebee CPE device and the application server (CPE-Server segment).
Was the client machine overwhelmed by the data coming from the server side and vice versa?
Do other flows from the same site during that time experience similar issues?
Do flows from other sites to the same application experience similar issues?
The above diagram is an illustration where packet loss happened on the network between Bumblebee CPE and the application server. In this example, the flow experienced some packet loss between Bumblebee CPE and the application server. If the CPE is installed on the client site, the CPE-Server segment implies WAN network.
How does one access the user experience dashboard?
Login to the Bumblebee portal
Under Intelligent Edge, click Dashboards
Select User Experience
Select a CPE device, time range
A list of flows will be displayed
How to obtain the performance insights of a flow?
Once you see the list of flows following the answers in the above questions, follow the steps below:
Click a desired flow, you should see a detailed meta data recorded for the flow, as shown below
Click the button Analyze for me to view the performance insights report.
How to read the Performance Insights Report
There are a few sections to the Performance Insights report, as explained below.
Network Diagram
The diagram illustrates the network components in the performance analysis: client, server, Bumblebee CPE.
It also illustrates, from the analysis of the meta data captured by the CPE, which segment of the network experiences packet loss.
Summary
This section gives a conclusion of the flow under analysis.
General Info
This section provides the general information regarding the flow.
Network Data
This section provides the round trip time (RTT) between the client and server, packets, bytes and throughput transferred in each direction by the flow under analysis.
Flow Quality Assessment
Our algorithm analyzes the captured meta data from the flow and provides insights to the quality of the flow. For example, it points out if there are packet loss, if yes, on which network segment. If the client side cannot keep up with the data transfer.
