There are several ways of switching to the Tracking mode. One of them (switching from the Map mode) has been described in the previous section. The other way is to move from the work list (Units mode). To do so, tap the line of the necessary unit in the work list.
The Tracking mode provides you with the possibility to monitor both unit's location on the map, and parameters received from a unit. Note that unit's location can be shown as an address (by default) or as unit's presence in geofences (the Geofences as addresses checkbox in the Other section of the OnTrak Fleet mobile client's settings)
In order for the units' movement arrows to be shown on the map in the mobile client, activate the option Show/Hide unit movement direction in the main interface of OnTrak Fleet.
History
You can view unit's events on the History tab. All the events are presented here chronologically and are formed on the basis of the messages received within 24 hours. The messages that were generated more than 24 hours ago are not registered as events after being unloaded from the black box.
Types of events and provided information:
Trip
Event's start time, duration, covered distance, unit's average speed.
Parking
Event's start time, duration, location address. The duration of the parkings which are the first and/or the last events of the day is not indicated.
Fuel filling
Event's time, amount of fuel filled, location address.
Fuel theft
Event's time, amount of theft, location address.
Choose an event in the history to display it on the map. In order for the map to be centered on a unit of monitoring, tap its icon.
Note that some values of event parameters (time intervals, amounts of fuel, unit's location) may differ from the values of the same parameters in the reports of the monitoring system. It occurs due to the implementation of different calculation systems in the web version of OnTrak Fleet and in the OnTrak Fleet mobile client. For example, upon detecting fuel fillings/thefts, the mobile client uses the time of the last message received before a fuel level change, while the web version of OnTrak Fleet uses time of the first message from the interval with the biggest difference of fuel levels. Moreover, the movement state in the OnTrak Fleet mobile client is determined only by the GPS speed, while other methods can be used in the web version of OnTrak Fleet.
Note that in the OnTrak Fleet mobile client the correctness of the data received on any event depends on the parameters indicated on the trip detector tab.
Info
The Info tab displays extended unit's information: location address, attached drivers (with phone numbers) and trailers, equipment data, values of custom fields, sensors, counters, and parameters.
Timeline
On the Timeline tab, you can visually evaluate the duration of events (the exclamation mark indicates their short duration), find out their number and get detailed information about the grouped events (by tapping a quantitative indicator). Events include trips, fuel fillings, and thefts. Besides, sensor state change (ignition sensor, custom digital sensor) and sensor values increase (mileage sensor, relative odometer, counter) are considered to be event types as well.
On the tab, you can view up to 4 event types simultaneously. Trips, fillings, and thefts are displayed by default at the bottom of the screen. To select other types, open the corresponding menu by tapping the event type at the bottom of the screen.
Events can be viewed on the map. To see the event, tap its tool tip. The map will be centered on it, and the event will be shown in one of the following ways based on the type:
trips — as a color track (if there are several tracks, they will be displayed in different shades of the same color);
fuel fillings and thefts — as a marker;
sensors — as a part of the track, which corresponds to the interval of sensor activation.
Tapping the tool tip again removes the event from the map.
When switching between the tabs in Tracking section, the events disappear from the map. Go back to the Timeline tab to return the events to the map.
The maximum number of events that can be simultaneously displayed on the map is 10.
The events selected for display on the map are added to the event cache. To see the cache, tap the 
icon in the upper right corner of the screen. After tapping on the event, the map centers on it. It is possible to remove one or several events from the cache (tap the delete icon next to its name) or all events at once (tap Remove all). The event cache is cleared if you change the type of events available for display.
Locator
The application supports a locator functionality. The locator is used to generate links and share the current location of the units. The locator can be available either from the work list (the Units mode) or from the Tracking mode. To generate a link, use a left swipe in the line of a corresponding unit, and tap the Target. In the menu that appears, choose the validity period of the locator's link (from 1 hour to 1 week). Then choose a required action: send a location link by any messenger on your smartphone, copy it, open in a browser, etc. Viewing is performed on the locator's map which becomes available upon clicking on the provided link.
