SD-WAN Tunnel Details
Overview
This page describes the graphics available for SD-WAN tunnels on the Details page.
For Fortinet, tunnels are aggregated into a single tunnel representation. Highlight is focused on showing a location talking to another destination location, so rather than showing the technical components, we represent the information in a way non-technical users understand - location to location.
Sidebar colour coding
Today only
When viewed for today only, the sidebar for each section on the Details page gives an indication if it is currently impacting the watch colour, associated heat tile colour and the grid row colour. This applies for collapsed sections also.
Traffic Load
Sidebar options
- Percent Actual
- Actual: Show volume of data received or sent (Percent is not available on tunnels so Actual is selected and cannot be changed)
- Standard MinMax
- Available on week or month only
Standard: Selected by default, shows an area chart using the maximum value as the data point
MinMax: Shows an average point and a vertical gradient bar for the minimum and maximum values recorded for the time period
- If you click, hold and drag across the chart to zoom in then this button appears in the top right of the chart - click to revert to the full time period, see separate section on zoom options for GIF examples
Axes and controls
- Download the traffic information to a CSV file, read more about the Download option
- Vertical axis
- Shows "bps" and scales depending on the volume
- Horizontal axis
- Adjusts according to the selected time period to show "hours" in day view and "days" in week and month views; redraws if the time zone is changed at the top right of the Details page
- Zoom options
- Drag: click, hold and drag across the chart to zoom into a time period; repeat if needed and if complete
Note: all new chart types are synchronised so they zoom in and out together
Click: on a week or month view, click on the chart to jump to that specific day view
See GIF example zoom options
Highlight displays the load value for each data point in the time period:
- Day
- Shows multiple data points per hour (one for each polling period, usually one to five minutes)
- Week
- Shows 24 data points per day (every hour), in MinMax view, Average for each hour is shown along with MinMax values
- Month
- Shows 6 data points per day (every 4 hours), in MinMax view, Average for each 4 hour period is shown along with MinMax values
Day view and Week/Month view with "Standard" selected - hover on a point to see date, timestamp and Max for In and Out as actual values
Week/Month view with "MinMax" selected - hover on a point to see date, timestamp, then Avg, Min and Max for In and Out as actual values
The settings below will be remembered when you next log in.
- Whether the panel is collapsed or expanded
- The status of any toggles
Summary
The summary shows the total values, peak and 95th percentages for in and out during the selected time period
- Total
- Shows the accumulated volume of traffic for the time period displayed, calculated by adding the volumes from the polled samples.
- Peak (Actual)
- The bits per second value reported is from the individual sample with the highest throughput for the time period displayed. It will be seen as the highest point on the chart. The Highlight peak therefore is the sample with the largest volume, divided by the number of seconds between samples (typically 180 or 60). .
- 95th percentile
- The highest recorded value during the time period ignoring the top 5%, read more about the 95th percentile and why it's useful
- Last sample
- Only shown for today, this is the last recorded value (the last good sample) for today with ? shown if no data was received
Line Availability
A purple background on the chart indicates a maintenance window. Tunnels in maintenance do not send alerts, change the colour of heat tiles nor decrement availability figures
Similar to Highlight's Line Health Availability, coloured blips, with the meanings shown below, are drawn on the chart.
| Blip Colour | Issue | Effect in Highlight | Included in Total outages? |
|---|---|---|---|
| Red | Tunnel down | Stability previously decremented (only red after contact re-established) | Yes |
| Blue | API call failure - recovered (patched from Mustard to Blue) | Stability previously decremented (only blue after contact re-established) | Custom |
| Mustard | API call failure - ongoing | Decrements stability and turns watch amber/red | Custom |
Discontinued tunnels and performance tests
Previously discovered tunnels may disappear from the SD-WAN network temporarily or permanently. These are deleted from Highlight automatically after 31 days - contact us to change this retention period. These discontinued tunnels are labelled on the Details page:
If a discontinued tunnel or test reappears on the SD-WAN network during the retention period, then these labels are removed and the item resumes collecting and displaying data.
If a discontinued tunnel or test does not reappear and the retention period ends, then the item is deleted from Highlight.
