Network: VPN Utilization

The VPN Utilization report shows a summary of the VPN status(es) for the selected gateway(s). Each row in the bar graph represents a day in the specified time range with the VPN statuses for that day summarized by the following colors:

• Blue: gateway is booting.
• White: gateway is shutdown.
• Grey: gateway does not have any active WAN link.
• Green: no VPN(s) associated with the current active WAN link is down.
• Yellow: at least one expected VPN is down, and at least one expected VPN is up.
• Red: all VPN(s) associated with the current active WAN link are down.

Basic Configuration Fields

• Gateway(s)^*: by default this is set to the gateway(s) selected in the gateway tree. Enter the name(s) manually to modify this field. Click on Filter to open the subfilter options.
• Report time range^*: use the drop-down menu to select from Previous Months, Previous Weeks, Previous Days or Range. Enter the numeric value in the field. When Range is selected, use the calendar pop-up to select the dates. Alternatively, enter the date and time manually (yyyy/mm/dd hh:mm).
• Multiple VPN Connect Mode^*: by default this is set to One VPN. In this mode, the report uses All Down to indicate no tunnel is up, not even one. The VPN Up will indicate that at least one VPN tunnel is up.
  

If a gateway has All VPNs selected, the VPN Utilization report will use All Up to indicate all VPN tunnels are up. The report uses At Least One Down to indicate some tunnels are down and at least one tunnel is up. The report uses All Down to indicate all tunnels are down. (Note: if a device has only 1 tunnel, then 1 tunnel means all.)

• Show detailed Info: when enabled, mouse-over tooltips and hyperlinks will be available in the graph area of the generated report. For the VPN Utilization report, a popup will display the time of the starting point of the section that the mouse is on and how long the section lasted for. Disabled by default.
• Output Format^*: select HTML to generate the report in the browser window. Currently HTML is the only available option.

Advanced Configuration Fields

• Hours per bar: defines how many hours are represented by each row in the graph, which effectively controls the “resolution” of the graph. To ensure performance when generating the report, the value must be set appropriately based on the Report Type Range as follows:

  • Greater than 30 days: set from 24 through 1000
  • Greater than 7 days: set from 12 through 1000
  • Greater than 1 day: set from 1 through 1000
  • One day or less: set from 0.5 to 1000. Note that values of less than 5 hours will set the graph units to be in minutes.

  The default is auto which automatically selects the best value for the time range.
