The Matrix Visualization is specific to the Node to Node test type, and summarizes the performance of the connections among your Nodes.
The visualization consists of a grid of cells, where each cell represents a connection between two monitored Nodes. The color of the cell indicates how the most recent test run compares to average performance over the previous 7 days.
Configuration
Configuring the Matrix Visualization is very simple; you just need to select the metric(s) that you want to track - Packet Loss, Latency, Jitter, or all three - and set thresholds for the warning and critical states, which determine the coloring of the cells.
In the example below, we are tracking Latency. An increase in Latency of 20% - 40% above the 7-day average will result in the warning state (yellow), and an increase of 40%+ will result in the critical state (red).
Understanding the Node to Node Visualization
Example 1 - Single Metric View
When visualizing just a single metric, the Matrix Visualization simply indicates that status of the metric using a color - green for good, yellow for warning, and red for critical. Here is an example based on the configuration above:
There is one cell in the yellow warning state. It represents the test run where the Washington DC node was the source, and the Atlanta node was the destination. By hovering over that cell, we see that the latency for the most recent test run was 18ms, versus a seven day average of 14.7ms, which represents a ?22% increase.
Example 2 - All-in-One View
When the visualization is configured to represent all three metrics, three shapes are included in each cell representing the status of each individual metric. A circle indicates that the metric is in good shape, a square indicates a warning status, and a triangle indicates critical status. The overall color of the cell is determined by the most severe status detected.
Here is an example of the all-in-one view:
The selected cell in the upper right again represents a test run where the Washington DC node was the source, and the Atlanta node was the destination. We see three shapes in the cell: circle, triangle, and circle, representing the status of Packet Loss, Latency, and Jitter respectively. This means that Packet Loss and Jitter are fine, but Latency is in the critical state. The cell is colored red to reflect this critical status.
