Tachyon Activity Record

A description of the benefits of Tachyon Activity Record feature and how the data can be retrieved.

Also known as Tachyon Inventory.

What is Tachyon Activity Record?

Tachyon clients capture certain types of event data in a local database (Persistent Storage) so that instructions can query later. Data is compressed and encrypted in a way that ensures a very low impact on device performance and security.

Tachyon Activity Record is similar to Windows Task Manager and Perfmon. On Windows client devices Tachyon continuously captures events, which enables all significant events to be captured as they happen. Other OS use polling, which requires the polling frequency to be regular enough to ensure brief events to be captured.

The type of data captured and is described below and the configuration options for each capture source are described in 1E Client - Tachyon client settings: Inventory module settings. There are Product Pack instructions for getting and setting these configuration options.

What are the capture sources?

The table below lists the capture sources supported by the Tachyon Activity Record feature, and on which OS they are supported.

How is the data managed?

The data is captured and stored to a local, encrypted persistent store and then periodically aggregated according to an ongoing daily, weekly, monthly window. This means that the data is held securely and the amount of data is minimized while still maintaining its usefulness.

How do I retrieve the data from the 1E Client devices?

Tachyon provides a number of Product Pack instructions that will let you interrogate your 1E Client devices for the data they hold.
