Data messages are messages sent to the server from the unit device. As a rule, they contain information about the unit speed and location at the time of sending, the message generation time, and other parameters depending on the device type.
When requesting data messages, you should select the way of displaying parameters.
| Option | Result |
|---|---|
| Raw data | All the parameters are displayed in one line in each table column. |
| Sensor values | The value of each sensor is displayed in a separate column according to the calculation table. By default, only the values of visible sensors are displayed. You can manually add columns with the values of other sensors. |
When working with data messages, the following features are available:
- viewing messages in the table;
- analyzing parameters in the chart;
- using the map;
- viewing the statistics.
Table of data messages
The table of data messages has the following columns:
| Column | Description |
|---|---|
| Time | The date and time of the message. |
| Registration time | The date and time when the message was received on the server (disabled by default). |
| Speed | The speed of movement of the unit according to the message. |
| Coordinates | The latitude and longitude of the position of the unit. The number of locked satellites is indicated in parentheses. |
| Altitude | The height above the sea level. If the device cannot transmit height data, a dash is displayed in the column. |
| Location | The address of the unit when sending the message. |
| Parameters (if available) | The values of the parameters of all available sensors. The messages can be filtered by parameters. Sensor parameters can be displayed in separate columns of the table. To do this, you should select the Sensor values option of displaying parameters. |
| Media | In this column, you can open images or videos sent by the unit. To do this, click on the icon |
| Delete | The selection of messages you want to delete. |
The following messages are highlighted in the table:
: alarm messages (SOS messages from the device or messages with non-zero values of the Alarm trigger sensor);
: black box messages (messages which were sent to the server not in real time but with a delay of a few minutes or days);
: messages with the location determined by Wi-Fi;
: messages with the location determined by LBS;
: imported messages.
The information on each colour and the message that corresponds to it is located in the Table legend section.
See more about working with the table and deleting messages here.
Chart of parameters
Apart from the table, you can see the result of requesting data messages in the chart. To go to the chart, select the Chart tab above the table.
When working with the chart, its legend is displayed in the work area. Here you can select the lines which should be displayed in the chart. Each line corresponds to a specific parameter and has its own colour. The colour is selected automatically each time you request the messages. The lines of all the parameters are displayed in the chart by default. To remove a line from the chart, disable it in the legend. For disabling or enabling all the lines, use the All lines checkbox. To see only one line and remove the others, point to it in the legend and click Only this.
When pointing to any place of the chart, you can see a tooltip with basic information about this point: the date, time, and the parameter values received at that moment (or the moment near to that). The tooltip shows the values of all the parameters selected in the legend. If there are too many of them and they don't fit in the tooltip, disable the unnecessary lines in the legend.
When you point to a certain line in the chart, the rest of the lines become lighter, and the name and value of this line is shown in bold in the tooltip. To analyse points in the chart, you can also use the Show detailed information about points tool.
The toolbar above the chart contains the following tools:
Tool | Description |
| Zoom in. You can use the mouse scroll wheel instead of this tool. |
| Zoom out. You can use the mouse scroll wheel instead of this tool. |
| Show all the interval. This tool allows you to zoom the chart so that it displays all the selected lines. |
| Select and zoom in on a chart area. To use the tool, click on the icon and select the area you want to zoom in. To exit the selection mode, click on the icon again. This tool is unavailable when using the Compare data tool. |
| Show detailed information about points. Click on the icon to see tooltips with information from the unit messages when you point to the chart points. If a tooltip contains coordinates, then when you click on them, it is possible to go to the map of a third-party source. See more. This tool is unavailable when using the Compare data tool. |
| Compare data. Read about this tool here. |
| Save as PNG. Click on this icon to download a PNG file with the image of the chart. The chart in the image looks the same as on the screen. |
Using the map
After querying messages, the track of the unit is displayed on the map.
Click on a row in the table or on a point in the chart so that the place from which the message has been sent is indicated on the map with the marker 
.
The track colour is blue by default. You can configure the track colour by speed or sensor value on the Advanced tab in the unit properties.
When you point to the track, the nearest message is searched. If such a message is found within a radius of 50 pixels, the point of receiving the message is highlighted by a pulsating circle, and detailed information is displayed in the pop-up window: the time when the message was received, address, the speed of the unit at that point, altitude, coordinates, number of satellites, sensor values. When you click on the coordinates, it is possible to go to the map of a third-party source. See more.
When you open other tabs, the map layout and the track lines are saved. To clear the map, you can disable the Messages layer or go back to the same-name tab and press Clear.
Statistics
This section provides general information about messages for the selected interval.
The units of measurement (metric or American) for values in statistics depend on the settings specified in the unit properties.
| Row | Description |
|---|---|
| Total messages | The total number of messages from the unit. |
| Total time | The interval between the first and the last message from the unit. |
| Distance | The mileage travelled by the unit. If there is invalid data in the indicated interval, the mileage in messages may differ from the mileage in reports. In such cases, the mileage in the reports is considered more accurate. |
| Average speed | The average speed value of the unit. |
| Maximum speed | The maximum speed value of the unit. |
