Manage devices using gRPC API methods (ConfigurationService)

Axxon One configuration settings are described in the ConfigurationService.proto proto file.

There are 2 methods used:

  1. Changeconfig.
  2. ListConfig.

ChangeConfig method

The ChangeConfig method allows to create, edit and delete any system objects.

Hereinafter, any system object or element will be called a unit.

Input data

  1. added – an array of units that should be added.
  2. changed – an array of units that should be changed.
  3. remove – an array of units that should be removed.

Unit structure

The type field determines what a unit is.

A unit can contain subunits (the units field). For example, a VideoChannel.0 unit may have a child unit Streaming.0.

Each unit has a uid field – it is a unit identifier, which consists of all the "parents" of the unit, separated by the "/" symbol. For example, the uid field of the Streaming.0 unit will be as follows: hosts/Node1/DeviceIpint.1/VideoChannel.0/Streaming.0.

Where

  • uid starts with "hosts",
  • Node1 is the node name,
  • DeviceIpint.1 is the device name,
  • VideoChannel.0 is the first video channel of the camera,
  • Streaming.0 is the first video stream of the channel.

In addition, a unit can contain any number of settings in the properties field.

Output data

In response to the method, the following data will be received:

  1. failed – the units that could not be added.
  2. added – the uid of the successfully added unit.

ListConfig method

The method allows to get a list of units.

Input data

unit_uids is an array of the units' uids to be obtained.

Output data

  1. units is a list of successfully found units.
  2. unreachable_objects is a list of temporarily unavailable units.
  3. not_found_objects is a list of not found units.

The units field is of UnitDescriptor type.

Data parameters:

  1. uid is a unit identifier, which consists of all the "parents" of the unit, separated by the "/" symbol. For example, the uid field of the Streaming.0 unit will be as follows: hosts/Node1/DeviceIpint.1/VideoChannel.0/Streaming.0.
  2. display_id is a short id, which is usually unique in a parent scope. For example, for a DeviceIpint.1 unit, the field display_id == 1 (sometimes type can go together with it).
  3. type is a unit type. For example, for a DeviceIpint.1 unit, the field type == DeviceIpint.
  4. properties is a list of unit settings.
  5. units are included units that can have either a full description or a short one. In this case, the field stripped == true, and the only fields that are available from the description are: display_id, type, uid.
  6. factory are included units that can be created for a given unit. The available fields are:
    1. type – a type of subunit that can be created;
    2. properties – a list of subunit properties.
