# Monitor fleet usage and utilization

> Use the Fleet Usage Monitoring page—Active Assets, Avg Utilization, Idle Time, Miles Driven—to spot underused vehicles and improve fleet ROI.

# Monitor fleet usage and utilization

Use the Usage Monitoring page to track how efficiently your vehicles are being deployed, identify assets that are idle or underutilized, and act on critical usage events before they affect operations or maintenance schedules.

## Before you start

* Manager or Admin role required.
* Usage data is generated by vehicles with active DataLogger OBD devices. Assets without a device show 0% utilization and no engine hours.

## Steps

### Open the Usage Monitoring page

1. In the left navigation, click **Fleet**.
2. Click the **Usage Monitoring** card (labeled "92% FLEET UTILIZED" on the Fleet Intelligence dashboard). The page opens at `Fleet Management › Usage Monitoring`.

### Read the summary tiles

Five tiles at the top of the page summarize the period (default: the most recent 7 days):

| Tile                | What it shows                                                                     |
| ------------------- | --------------------------------------------------------------------------------- |
| **Active Assets**   | Number of assets that recorded at least one trip                                  |
| **Avg Utilization** | Fleet-wide average utilization percentage                                         |
| **Idle Time**       | Total hours the fleet spent idling                                                |
| **Miles Driven**    | Total miles driven across all assets                                              |
| **Underutilized**   | Count of assets flagged as underutilized (click to filter the Fleet Assets table) |

### Change the date range

Click the date range label at the top of the page (for example, "May 15, 2026 — May 22, 2026") or use the **7D**, **30D**, and **90D** buttons on the Utilization Dynamics chart.

### Read the Utilization Dynamics chart

The **Utilization Dynamics** chart plots two metrics over time:

* **Active %** — the percentage of assets active on each day (left axis, 0–100%)
* **Avg Engine Hrs** — average engine hours per active asset per day (right axis)

Hover over a data point to see the exact values for that date. Use this chart to spot days when utilization dropped sharply or engine hours spiked.

### Review the Fleet Assets table

The **Fleet Assets** table lists every registered asset with the following columns: **Asset**, **Device**, **Trips**, **Miles**, **Engine Hrs**, **Util %**, **Status**, and **Last Active**.

* Assets above the utilization target show "Above utilization target" in the Status column.
* Assets below the target show "Below utilization target" and may be candidates for redeployment.
* Click **View All Report** (top right of the table) to open the full fleet report at `Fleet Reports`.

Sort the table by any column header to find the highest or lowest performers.

### Act on Critical Events

The **Critical Events** section lists usage-triggered alerts categorized by type:

| Type filter  | Events included                                                              |
| ------------ | ---------------------------------------------------------------------------- |
| **Idle**     | Excessive idling alerts (for example, "Truck #221 idle > 4 hrs today")       |
| **Low use**  | Low runtime alerts (for example, "Excavator #11 under 2 hrs use this week")  |
| **High use** | High runtime alerts (for example, "Vehicle #310 high runtime (>12 hrs/day)") |

Use the **All**, **Idle**, **Low use**, and **High use** filter tabs to focus on one category. Click **Resolve All Events** to clear acknowledged events from the list.

### Review the Low Efficiency Priority list

At the bottom of the page, the **Low Efficiency Priority** section highlights the bottom five assets by utilization rate under the heading "Bottom 5 Assets." Each asset shows its utilization percentage and a short reason label (for example, "Stationary for 4 Days," "Short-Haul Only," "Idle Outlier," "Low Weekly Trips," "Below Fleet Avg").

Click **Flag asset** next to any vehicle to mark it for follow-up or reassignment review.

## Result / verify

After opening the page, the summary tiles show current fleet totals and the Utilization Dynamics chart displays at least one data point per day for the selected range. Assets with 0% utilization appear in the Fleet Assets table with an "Inactive" status and no Last Active date.

## Troubleshooting

**All assets show 0% utilization** — confirm that OBD devices are powered and reporting. See [Verify device connection](/gps-tracking/device-setup/verify-device-connection) and [Device not reporting data](/gps-tracking/gps-troubleshooting/device-not-reporting).

**Critical Events list shows only sample data** — this label appears when no real events have been generated yet. As vehicles accumulate trips and crossing usage thresholds, live events replace the sample entries.

**Underutilized tile is clickable but filters nothing** — no assets currently fall below the utilization threshold. The filter clears automatically when the count is zero.
