Reports & Data Matrix
The Reports page presents the KPI Diagnostic Table — a data completeness matrix that gives you a structured, at-a-glance view of which vehicles in your fleet have usable data for each metric category over a given time period.
It is not a report in the traditional sense of a document you generate and send. Instead, it functions as a diagnostic tool: before you rely on KPI tiles, trip exports, or formal reports, use this page to verify that your fleet data is complete and that your Wialon units are configured correctly.
What the Matrix Shows
The matrix is organized as a table where:
- Rows represent individual fleet units (vehicles).
- Columns represent metric categories.
- Cells indicate whether data exists for that vehicle in that category over the selected date range.
This structure makes it immediately visible when a vehicle is missing data in a specific category — which often indicates a sensor configuration issue, a GPS device problem, or a gap in Wialon unit setup.
Metric Categories (Columns)
The columns are organized into logical groups. Each group can be toggled independently, letting you focus on the categories relevant to your current review.
Mileage
| Column | Description |
|---|---|
| Distance | Total distance driven by the unit in the selected period. |
| Trips | Number of trips recorded. |
| Drive Time | Total time the unit was in motion. |
| Inactivity | Time the unit was stationary (engine on but not moving, or engine off). |
Speeding
| Column | Description |
|---|---|
| Speed Events | Number of recorded speeding violations (events where the unit exceeded a configured speed threshold). |
Speed event data requires that speed thresholds be configured for each unit or group in Wialon. If no thresholds are set, this column will show no data regardless of actual vehicle behavior.
Fuel
| Column | Description |
|---|---|
| Fuel Consumption | Total fuel used during the period, if a fuel sensor or calculated consumption is configured. |
Ignition
| Column | Description |
|---|---|
| Ignition Events | Count of ignition on/off cycles recorded during the period. |
Sensors
| Column | Description |
|---|---|
| Custom Sensor Activity | Activity recorded from any custom sensors configured on the unit (e.g., door sensors, PTO, temperature probes). |
Column Group Toggles
Above the matrix, a row of toggle buttons allows you to show or hide entire column groups. For example, if your fleet does not use fuel sensors, you can hide the Fuel group to reduce visual noise and focus on the categories that matter for your operation.
Active groups are highlighted. Click a toggle to enable or disable that group. Changes take effect immediately and do not affect the underlying data query.
If you are auditing a specific compliance area — for example, verifying that all vehicles have speeding data before generating a compliance report — hide all groups except Speeding. This gives you a clean, focused view of exactly which units have gaps.
Selecting a Date Range
The date range picker at the top of the page controls which period the matrix covers. All metric columns are calculated for the selected range.
- Use the preset buttons (Today, Last 7 days, Last 30 days, This month) for common ranges.
- Use the calendar picker for custom start and end dates.
Very large date ranges (e.g., a full year) queried across a large fleet can take several seconds to load, as the matrix aggregates data for every unit and every metric category in a single pass. For diagnostic purposes, a 7-to-30-day window is usually sufficient.
Filtering Units
By default, the matrix shows all units in your Wialon account. When working with large fleets, you can narrow the view:
- Unit search: Type a unit name or partial plate number in the search field to filter rows.
- Group filter: Select a Wialon unit group from the dropdown to show only units belonging to that group.
Filters apply immediately. The visible rows are the only ones shown in the matrix — filtering does not affect the data calculations, only which rows are displayed.
Reading the Matrix: Identifying Missing Data
Each cell in the matrix uses a visual indicator to communicate data availability:
- Filled / colored cell: Data exists for this unit and metric in the selected period.
- Empty / muted cell: No data was found. This typically means one of the following:
- The metric is not configured for this unit in Wialon (e.g., no fuel sensor).
- The GPS device was offline or not reporting during the period.
- The unit was not in use during the selected date range.
Distinguishing Configuration Gaps from Genuine Inactivity
A vehicle with no trips and no distance recorded in the past 30 days could mean the vehicle was legitimately out of service — or it could mean the GPS device has a connectivity issue. The matrix helps you see patterns:
- If a unit shows no data across all columns, the device is likely offline or the unit is inactive.
- If a unit shows trip and mileage data but no fuel or sensor data, the sensors are probably not configured in Wialon.
- If one unit is missing data that all other similar units have, it likely has a unit-specific configuration gap.
Use the matrix at the start of each reporting period to catch data gaps before they become audit problems. A 5-minute review each Monday can save significant time when compiling end-of-month compliance reports.
Relationship to KPI Dashboard
The data completeness matrix and the KPI Dashboard are complementary. The KPI Dashboard surfaces aggregated fleet performance metrics; the Reports matrix tells you whether the underlying data feeding those metrics is complete and reliable.
Before drawing conclusions from KPI tiles — for example, comparing idle time across units — check the Reports matrix to confirm that all relevant units have sensor and ignition data for the period in question. Units with missing data will appear as zero or will be absent from aggregated calculations, which can skew averages and rankings.
