Unit Groups

Created units can be formed into groups. Groups are used to unite units on the basis of any criteria.


To work with unit groups, choose the corresponding mode in the 'Units' panel.



To create a group, click 'Create', fill in general properties, choose units forming a group, and click OK. The group will appear automatically in the work list of the 'Monitoring' panel (in the group view mode) of the account it has been created in.



A list of unit groups created is displayed in the work area. Groups are listed in the alphabetic order. To the right of each group name you can see a number of units in it. To see names of units forming a group, place a cursor on the necessary group (names are shown in a tool tip). To facilitate a search of the necessary unit group, use dynamic search above the list.


The following icons are used to perform standard actions over units:

 or  — Edit or view unit group properties — depends on your access (change name, add more units, remove units, manage access, etc.). The dialog of unit group properties can contain up to 4 tabs which were described above:

  • General
  • Access
  • Icon
  • Custom fields

 — Create a new group using this one as a basis (copy).


 — Delete the group from the system. Deleting a group does not mean deleting the units included. If the icon is inactive, then you don't possess enough access rights to perform such an action.


Working with unit groups, consider some specific features of access rights:

  • A group can be used to give a user access to several units at once.
  • With groups, access to a unit can be widened but not narrowed.
  • The creator of the group must have rights to units in this group. Otherwise, it would not be possible to transfer the rights properly.
  • To add/remove unit to/from a group, you are required to have the rights 'Edit ACL propagated items' on this group.


Application of Unit Groups

Unit groups are widely used in the user interface of OnTrak Fleet:

  1. Online tracking of unit groups:
    • display/remove from the map a group of units with one mouse click;
    • send commands to a group of units at once;
    • observe a certain parameter (sensor value, movement state, etc.) for a group of units in one window.
  2. Advanced reports:
    • all tabular reports can be generated for a unit group;
    • draw tacks of all grouped units on the map.
  3. Configuring jobs, notifications, and routes:
    • When configuring jobs, notifications or routes, they can be applied to a group of units at once, which accelerates the process.

Unit groups also have some specific functions in the management system, which were described above.


At that, unit groups are easy to handle. Deleting groups does not mean physical removal of units belonged to this group. That is why you can easily create, manipulate and delete groups. Besides, the dynamic formation of groups is supported — see Notification Action. It means, if some preset conditions are met, a unit can be added to a group automatically or removed from it.
