To view tracks, you should have the Request reports and messages access right to the units.
To view a track, open the Tracks tab and do the following:
As a result, you can see the line of the unit movement mapped taking into account the specified parameters, if there are messages with coordinates for the selected interval. When the track is shown, you can't show its parameters or the selected unit. In case of an error, delete the wrong track and create a new one.
If you have to wait for the result for a lot of time, then you have a low-speed Internet connection or the specified interval is too long.
A track or its part can be shown on the map as a dotted line if there is not enough data. For example, if the Maximum interval between messages parameter (the Advanced tab of the unit properties) has been exceeded, or the number of satellites is less than four (if the message validity filtration is disabled).
The limit on the number of satellites is not applied to Wi-Fi data messages, therefore, the tracks based on such messages are always shown as a solid line.
If a unit has a Private mode sensor with the Do not show unit location option enabled, then a straight dotted line which connects business trips is shown instead of a private trip.
