Idling Report (Desktop)
The Idling Report helps you understand how much time your vehicle or equipment spends idling versus working, and how much fuel is burned while idling. It’s designed to highlight waste, target training or policy changes, and reduce unnecessary fuel and maintenance costs.
The Idling Report utilizes idling data that comes from specific tracker types (TennaFLEET, TennaCAM, TennaCANbus) and certain OEM integrations that can distinguish if the asset's engine is running but not moving (i.e., idling).
Note: If Data Access Controls is enabled on your account, users will only see the assets to which they have access when viewing this report.
Included In This Article:
Use the Idling Report to:
- Identify assets with excessive idling and prioritize coaching or policy changes.
- Quantify fuel waste from idling in gallons (and cost, when combined with fuel price).
- Compare idling behavior across sites, time periods, tracker types, or fleets.
- Support maintenance and lifecycle planning by understanding how much of engine time is productive vs. idle.
Sample Report – Overview of Idling Report Fields
- Major Category: Assets categorized as Equipment, Truck or Vehicle will pull into the Idling Report if their tracker is online and they had activity during the time period the report is run for.
- The exception is AEMP assets which, if toggled on to appear in the report, will always be shown regardless of reported activity for that time period.
- The Asset Category column group is collapsed by default. If expanded, columns will be shown for Subcategory 1, Subcategory 2 and Subcategory 3.
- Organization (and sublevels): The asset's designation in your company Org Chart
- Asset Details:
- Fleet Number
- Asset Name
Pro Tip! Hover over the Fleet Number or Asset Name to view an Asset Details popover. Click the eye icon to open the full Asset Details page.
- Status
- Year
- Make
- Model
- Site Assignment
To learn more about these asset attributes, view Assets Overview.
- Tracker Type: The type of Tenna tracker installed on the asset, if applicable.
Important! Assets with an active OEM integration will show TennaIN AEMP Feed as the Tracker Type.
- Total Idle Time: How long the asset was idling (engine on, but not working/moving). Values in this column capture the sum of all idle time from the total trip duration for all trips per asset within the selected date range.
Pro Tip! Total Idle Time and Avg Idle Time per Trip can be shown in as a decimal rounded to the nearest tenth of an hour or as xx h xx m xx s. Click the gear icon on the right side of the grid and toggle the Hours Format on or off to your preference.
Important! Idling time duration excludes times when the OEM-installed Power Takeoff (PTO) is engaged, in most cases. TennaFLEET II Trackers, TennaCAM 2.0 and TennaCANbus can detect if OEM PTO is engaged.
- % Idle: This shows the percentage of time the asset is reported idling (idle duration) based on the overall run time for that trip (trip duration).
Pro Tip! This makes it easy to compare idling behavior across different assets and trackers.
- Average Idle Time per Trip: This shows the average idle time across all reported trips within the selected date range.
- Trips for AEMP assets are unknown, so N/A is shown for AEMP assets.
Pro Tip! This helps you spot patterns like long warm-ups, long lunch idling, or end‑of‑day idling.
- Idle Fuel Consumed: Fuel consumed during an idle state, in gallons.
- Ignore ECU Idle Hours: (Yes or No) shows if the asset has been configured to ignore idle hours as reported by the ECU
- ECU Idle Hours Available: (Yes or No) shows if the asset's ECU is capable of reporting idle hours
Idling Report FAQs
Does idle time count towards utilization?
Idle time does count toward utilization. When a machine is running, it contributes to wear and tear on the asset, and Tenna factors run time into utilization regardless of whether idling took place during that run time event.
How do Tenna trackers determine that an asset is idling?
Idling is reported when the engine is on (ignition: ON) and the vehicle is moving at less than 5 mph for a period of 3-5 minutes.
Why don't other Tenna trackers, like TennaMINI and TennaINTEL, report idle time?
TennaMINI and TennaINTEL trackers report ignition on and ignition off states, but do not distinguish between and ignition on, and moving or not moving, event.
How do I show or hide AEMP assets in the Idling Report?
Click the gear icon on the right side of the grid to open the Settings menu. Click the toggle on or off to show or hide AEMP assets.
How does an AEMP asset report idling?
Tenna calculates idling from information received by the asset's AEMP feed, like engine hours and idling hours. The frequency at which Tenna receives these data points from an AEMP feed varies by OEM.
For AEMP assets:
-
Total Idle Time = the sum of the idle duration for all data received for the specified date range.
-
% Idle = dividing the total run time based on the duration captured, divided the idle duration captured.
Why can't AEMP assets report Average Idle Time per Trip?
Average Idle Time per Trip cannot be calculated for AEMP assets because Tenna does not receive trip or cycle data from the OEM.
