Network: Link Utilization Report

The Link Utilization report shows a high level of detail for WAN data link connectivity state over time. It is best used for a small number of gateways and is ideal for identifying connectivity issues that occur at specific times of day.

Note: in order to run this report on ALEOS devices, ALEOS 4.8.0+ and AMMER are required.

The fields for the Link Utilization report are identical to those in the Availability Trend, Availability Details and Coverage Trail reports.

A color-coded legend shows the connectivity states:

• Blue: the gateway was booting.
• Green: the link was up.
• Purple: the gateway shutdown properly.
• Pink: the gateway experienced an unexpected (i.e. unplanned) shutdown
• White: the gateway was powered off.

Hovering over any point on the graph displays the date, time, link name and its connectivity state and connection duration (this requires the Show detailed info checkbox to be enabled).

For details, click on any point on the graph to open up a new tab showing each contributing event. This feature requires the Show detailed info checkbox to first be enabled in the advanced configuration options for the report and is recommended for advanced users.

The data below the map provides individual event records, with a location link.

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).
• Limit to map area^*: select Not Limited to include data from any geographic location. Select Manually defined area to create a temporary zone for the analysis – only data from inside this zone will be included in the report. Select One or more zones to limit the analysis to one or more predefined zones (see the AMM Operation and Configuration guide for more information about zones).
• Exclusion Zones: allows the report to exclude data from one or more predefined zones (see the AMM Operation and Configuration guide for more information about zones). Leave this option checked (default setting) to include data from any geographic location. Uncheck this option to specify zones to exclude data from.
• Limit to network types^*: by default Aggregated Report Only is selected. This will show a report for each gateway selected and if the network is up or down for all networks on the gateway. All Network Types has the option to show the Aggregated Report and also breaks out the status of each network card for each gateway. One or more Network Types has the option to show the Aggregated Report and allows the network type(s) to be specified. It is case insensitive and each network type should be comma separated.
• Show the call as down when the VPN connection is down: provides an additional indication on the graph to show when the VPN connection was down during a call.
• Show friendly names if available: when enabled, shows WAN link names in the report if they have been set in the gateway’s configuration.
• Show detailed Info: when enabled, mouse-over tooltips and hyperlinks will be available in the graph area of the generated report. Disabled by default.
• Output Format^*: HTML is the only format supported for this report.
• Save for later or schedule a run time: enable to create reports that can be saved for future use. See Saving and Scheduling a Report for a Later Run Time for more information.

Advanced Configuration Fields

• Max bootup time^*: enter the amount of time (0 to 1800 seconds) to allow the gateway to boot before reporting CALLDOWN. The default is 180.
• Max time between events^*: enter the amount of time (0 to 86400 seconds) to allow between gateway events before considering the unit non-responsive. The default is 3600.
• Active link colors: click on each link to change the default color (use the color picker).
• 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.
