Avatar

Avatar Device Driver creates a replica of another device that synchronizes with the original device. Avatars are most widely used to create local copies of remote device accounts connected to the local server via distributed architecture.

Just like any other device, avatars keep a separate device snapshot and collect variable/event history.

Avatars differ from Agents and Local Agents.

Avatar Driver is accompanied by an Avatar Management model that enables automatic creation, updating, and removal of avatars for a set of remote devices connected to Iotellect Server via distributed architecture. This model can be created like any other resource.

Avatar management module configuration (available via the Edit Additional Properties action of the model context):

Module global configuration settings:

• Module Enabled controls avatar management module functioning in general.

• Avatar Auto Removal enables the automatic destruction of avatars once their source devices are removed.

• Force Synchronization option enables the one-off creation of avatars for selected source devices. This option is automatically switched off once the process is finished.

Configuration of remote servers that the avatars will be created for:

• Enabled setting enables/disables configuration record

• Distributed Connection Name is a name of a distributed architecture Provider

• Mount Point Name is the name of the above Provider's mount point

• Custom Prefix is a prefix that will be added to remove device names to avoid collision with local device names

• Local User is a user account under that the avatars will be created

• Device Type is a list of device types for that the avatars will be created

None defined.

None defined.

• Source Device. Path of a device context for that the avatar is created.

• Resource Groups. Groups of remote device entities that will be replicated by the avatar. The Resource Groups table includes the Enabled column defining whether a certain resource group's replication is enabled and the Group Name column defining the name of the replicated group. By default, entities of the Remote group are replicated.

• Excluded Resources. Data table indicating which resources from the remote device should not be replicated by the avatar. Common resources are excluded by default.

• Source Device Check Period. Advanced setting indicating how frequently the avatar should check status of the remote device. The default is set to 10 seconds.

• Show Source Device Status. Setting to False will prevent the avatar from retrieving the source device status, which may be necessary to prevent an accumulation of waiting threads or a large synchronization queue during an initial sync of many new devices. Default value True.

Avatar's assets are replicated from the source device.

Avatar's device settings are replicated from the source device.

Avatar's device functions are replicated from the source device.

Avatar's device events are replicated from the source device.

This driver makes the device Online if the Source Device context is available.

Avatar's connection status is not bound to the connection status of the source device itself.

Avatar driver performs synchronization of the avatar with its Source Device according to the following algorithm:

• Information about Source Device's assets, variables, functions, and events available in Resource Groups is read

• Values of the Source Device's variables are read

• Avatar subscribes to selected setting variable updates and events of the Source Device
