Display Latency, Loss, and Jitter on Circuits

To display graphs for latency, loss, and jitter on each circuit in your overlay network:

  1. Click Tunnel. Each line in the graphs indicates one circuit. The legend to the right indicates the color of each circuit.
  2. Click the Filter icon to select specific circuits to view.
  3. Click the PDF icon to open a PDF version of the graph in a new tab.
  4. Hover over a point on a line to open a hover box with details for that point in time.
  5. Click a point on a line to display average latency, loss, or jitter in that circuit at that point in time:
    1. Click a site to see latency, loss, or jitter for all tunnels at that site.
    2. Click a tunnel to see hourly latency, loss, or jitter for that tunnel.
    3. Click Overview to return to Network Health ► Tunnel.
  6. To highlight specific circuits:
    1. Click a circuit in the legend to select it. To select more than one circuit, hold down the Shift key.
    2. Click the Highlight icon that appears. The selected circuits are highlighted on the map.
    3. To display all circuits again, click the Highlight icon.

Display Application Performance by Carrier

To display application performance by carrier on a geographical map of the overlay network:

  1. Click Carrier. Circles on the map represent each carrier. The legend to the right indicates the color of each carrier.
  2. Select Latency, Loss, or Jitter to change the data displayed.
  3. Click the Filter icon to select specific carriers to view.
  4. Click the PDF icon to open a PDF version of the map in a new tab.
  5. Hover over a carrier's circle to display a hover box with details for that location.
  6. Click a circle on the map to display that location's performance by loss, latency, or jitter:
    1. Click a point on the graph to see a graph of performance for each carrier at that location.
    2. Click a carrier to see performance for each vEdge router at that site.
    3. Click a vEdge router to see that device's performance over time.
    4. Click Overview to return to Network Health ► Carrier.
  7. Hover over the map to display map functions:
    1. Click Search to search for a geographical location by name.
    2. Click the + (plus) or - (minus) zoom icons to zoom in or out.
    3. Click Home to return to the world-wide view.
    4. Hover over the right arrow for other map functions, such as selecting a zoom area and panning.
  8. To highlight specific carriers:
    1. Click a carrier in the legend to select it. To select more than one carrier, hold down the Shift key.
    2. Click the Highlight icon that appears. The selected carriers are highlighted on the map.
    3. To display all carriers again, click the Highlight icon.
