1E 8.1 (on-premises)

Tachyon Features

An overview of all the Tachyon features and enhancements. The page provides a brief overview of each feature and links to other pages with more detail.

Explorer features

The Explorer application gives you the ability to investigate, remediate issues and manage operations across all your endpoints in real-time. For more information, please refer to Tachyon Explorer 8.1 - Using Tachyon Explorer.

Here's an overview of the features available in the Explorer application.

Questions, actions and their responses

Explorer lets you directly question connected devices to retrieve responses, run actions, and get real-time information from them. The Explorer front-end capabilities ensure fast querying, investigation, and remediation.

The questions, responses and actions feature includes:

  • Graphical display of response information

  • Instruction impact assessment

  • Response history.


For more information on Instructions and their responses, please refer to:

Exporting data from Explorer

Results visible in Explorer can be exported to files containing comma-separated values (CSV) or, in the case of the Export all option on the instruction response page, tab-separated values (TSV), and results can be marked for export at the point of asking a question to automate the process. Explorer lets you export the data on a number of pages to CSV files:

  • Instruction history

  • Responses - you can export a single page or all results once the Instruction has finished gathering responses - these can then be used for auditing purposes or to drive external programs

  • Drill-down responses

  • Device information


For more information on exporting data from Explorer, please refer to:

Coverage, question filters, view filters and follow-on instructions

Questions and responses can be tailored to focus on specific ranges of devices through the use of coverage and filters:

  • Coverage acts first to let you restrict the devices that will be asked a given question

  • Question filters act before devices have responded to narrow the responses that are sent

  • View filters act after the responses have been sent to focus the responses presented to the user and to determine the input into the follow-on instructions

The responses to initial questions can be further refined by asking follow-on questions or actions, allowing Tachyon questioners and actioners to focus in on the results they want to see.


For more information on coverage, question filters, view filters and follow-on instructions, please refer to:

Approval workflow

To enhance the safety of running actions in the Tachyon system, there is an approval workflow that ensures that every Tachyon action requires the approval of designated approvers before it can be run. To make it even safer, someone with approval permissions cannot approve their own action.

When an attempt is made to run an action, the Tachyon approval workflow sends an email and a Tachyon notification to all the approvers associated with the action. Any of the approvers may approve or reject the request to run the action.


For more information on the Approval workflow, please refer to:


Users must provide their user credentials when attempting to run an action, this prevents unauthorized access by a third party attempting to make use of an unattended computer.

Actions can also be configured to require two-factor authentication, where the user attempting to run an action is challenged to enter a unique, one-time Tachyon authorization code that has been sent to them via an alternative method - such as email or via a registered mobile.


For more information on authentication, please refer to:

Task-based organization for accessing and scheduling instructions

Tachyon provides a way of accessing the questions and actions that is organized around the way that network administrators typically interact with their network. This interface also lets you run the Instruction using a schedule.

The Explorer→Instructions→Tasks page in Tachyon Explorer provides a structured view of the instructions defined in the product packs. It also lets you schedule the tasks so they can be run in the future or according to a particular schedule.

Using task groups

The benefit of using Tasks lies in the task group structure that is defined in the product packs. It is this structure that enables you to focus in on specific task areas to find the particular instruction that you want.

For example you may be interested in instructions related to particular software vendor's products. Depending on the Instructions that you have uploaded to your Tachyon system you may see the following structure:

  • At the top-level there is a Software Vendors task group whose children are 1E and Microsoft.

  • Underneath the 1E task group there is a Tachyon group that contains Configuration, Diagnostics and Verification groups as well as a couple of Instructions.

  • Underneath the Microsoft task group is the Configuration Manager task group containing Instructions related to that product.


For more information on using Task groups to access and schedule Instructions, please refer to:

Inventory and connectivity

The Devices page in the Tachyon Explorer shows you all the devices that have connected with Tachyon and their current connection status. There are two views provided that let you research the devices: the devices table and the devices dashboard, please refer to The Devices Table and The Devices Dashboard for more details.


For more information on inventory and connectivity, please refer to:

Settings features

The Settings application lets you configure Tachyon system and application settings. For more information please refer to the Using Settings section of this documentation.

Here's an overview of the features available in the Settings application.

Instructions, product packs, Instruction sets and permissions

Tachyon lets you investigate your network using questions and actions, which are collectively known as Instructions.

You can load Instructions into Tachyon, either individually or via a Product Pack, which is essentially a zip file containing one or more Instructions. Tachyon comes with a range of pre-framed questions and actions in the form of product packs, providing extensive out-of-the-box capabilities that can be extended as new and updated product packs are made available.

Tachyon permissions for the Instructions are handled using Instruction sets. You create Instruction sets, then define roles which specify particular permissions on those sets and then assign the roles to users. Each Instruction is only allowed to reside in one Instruction Set, which associates it with a role and thereby the users that have that role and can run the Instruction. The roles have associated Management groups that determine the devices that users with the role have access to.

When Instructions are loaded into Tachyon they are placed in the default Unassigned Instruction Set, so you must move them into previously created Instruction sets before they can be run.


For more information on uploading product packs into Tachyon and managing Instruction sets, please refer to:


Connectors are used to connect to other 1E and third party systems and populate repositories. When more than one connector to different data sources are used, the information from those different data sources is de-duplicated and normalized into a single cohesive view that is then stored in a repository. In this way you can use the data from different sources to augment each other and build a better picture of "what's out there?". For example, you can sync inventory data from Configuration Manager into an inventory repository, which will fetch information about your Windows devices. You could then augment that with inventory data synced from Tachyon which could include information about non-Windows devices where the Tachyon client has been installed.


For more information on connectors, please refer to:

The following connectors are supported:


Repositories are used by applications to process and store information. For example the Patch Success application uses both an inventory and a BI repository to process the information needed to report on how successful patching is in your enterprise. Normally a connector is used to connect a data source to an appropriate repository.


Repositories are also useful when you want to segregate different types of data. For example, you could have one inventory repository for Configuration Manager inventory data, and another one for BigFix data. Alternatively, you can have connectors to different inventory sources pushing data into one repository. Any Management Groups that you create will span all the repositories you have.


For more information on managing repositories, please refer to:

Device Tags

Device Tags are generally associated with Explorer and can be used when setting coverage to target Instructions to particular devices, but they can also be used to define Management Groups optionally used by all applications.

Device Tags must be defined by a Full Administrator before they can be used to tag devices or used to set the coverage of Instructions.

This is done from the Settings→Configuration→Custom properties→ Device Tags page, which can be viewed by users with the Full Administrator role.

Software Tags

Using Software Tags allows you to create custom labels and associate them with the software titles you have deployed in your estate.

You can do this from the Settings→Configuration→Custom properties→Software Tags page, which can be viewed by users with the Full Administrator role.

Using Software Tags allows you to create custom labels and associate them with the software titles you have deployed in your estate. An administrator with either the Full Administrator or Group Administrator role can set Software Tags in their environment, they can also create Management Groups based on the tag name and value. For details about configuring Tachyon users, Roles, and Management Groups refer to the Permissions Menu pages.

In short, you can work with Software tags by:

  1. Creating your Software Tag.

  2. Associating the new tag with a software title.

  3. Creating a Management Group based on the Software Tag name and Tag value rules (This step can be run anytime before evaluation).

  4. Evaluating the new Management Group by running a Basic Inventory Consolidation.

If an administrator adds or modifies Software Tags or associations, they will have to run the Management Group evaluation report again to see the updated devices reflected in Inventory.


Schedules can be created to execute specific operations on repositories in Tachyon so that they are kept up to date with their data sources and processing. These operations include:

  • Syncing data sources to repositories using connectors

  • Processing the BI data cube.

Repository schedules are different to Instruction schedules that can be set in Explorer.


For more information on setting schedules, please refer to:

Consumers, Applications, Components and Providers

There are pages in the Settings application for each of these. They are described in the following table:

Configuration objects



These can access Tachyon using the Tachyon Consumer API. To enhance the security of the Tachyon system, only consumers that have been registered on the Settings→Configuration→Consumers page will be allowed to access Tachyon.


Features of Tachyon that are hosted in the Tachyon Portal. Applications are generally Consumers as they need to interact with Tachyon using the Tachyon API. These are available on the Switch App menu.


These form part of SLA and cannot be changed or altered by a user. These can be viewed using the Settings→Configuration→Components page.


These are components that can be configured to provide a particular operation in SLA. These can be viewed and configured using the Settings→Configuration→Provider configuration page.


For more information on Consumers, Components and Providers, please refer to:

Information pages

Information on your Tachyon license is available, as well as the ability to re-activate it following an update.

You can view information on the Tachyon system information for the Consumer, Coordinator, Background channel, Core and Switch.


For more information please refer to:

Monitoring log files

The monitoring pages let you view how Tachyon is performing its tasks. Four key log pages are provided:



Process log

Whenever you execute a sync or process a repository the steps are displayed here. This page is updated in real-time and shows the status of each step as it happens.

Sync log

The results of performing a sync are displayed here.

Infrastructure log

Information on the Tachyon infrastructure is displayed here, such as: license status and instruction workflow.

Audit information log

This page displays information on the Instructions that have been run in Explorer. This includes the instruction text and the user that requested it.


For more information on monitoring please refer to:

Defining users and roles

Tachyon users or groups can be added from AD. They can be assigned roles that determine what aspects of Tachyon they can access. Custom roles can be created that let you associate particular permissions on particular Instruction sets for particular management groups.


For more information on users and roles please refer to:

Management groups

Management groups use inventory-based rules to define groups of particular devices, they are implemented in SLA and then made available to Tachyon applications and other consumers. After a management group is defined, each time the inventory is updated the device membership of the groups is re-evaluated by applying the management group's rules to the new inventory.

Custom roles can be created that tie particular Instruction sets to particular management groups. This means you can not only set the permissions for users to access the Instructions in specific Instructions sets, you can also determine which devices they can target using those Instructions.

Once defined, management groups can then be used to set the coverage for Instructions in Explorer and also which devices can be targeted by particular users. Management groups are also used by the Patch success and Guaranteed state applications to determine which devices are being targeted.


For more information on management groups, please refer to:

Uploading Instructions into Tachyon and creating Instruction sets

You determine the capabilities of Explorer by uploading Instructions from product packs into Tachyon. Product packs are either provided with the release or downloaded from the Tachyon Exchange. Once the Instructions have been uploaded into Tachyon you then need to put them into Instruction sets. The Instruction sets can then be associated with custom roles to determine the permissions applied to the Instructions. The custom roles are then applied to users to determine which Instructions each user has access to.


For more information on uploading product packs into Tachyon and managing Instruction sets, please refer to:

The Tachyon client

The Tachyon client is a feature of the 1E Client. On Windows devices, the 1E Client provides client features and modules for other 1E products. On non-Windows devices, the 1E Client only provides Tachyon client features.

Tachyon enables rapid response to instructions using the Tachyon client, which supports the retrieval of information, running actions and device tagging. The 1E Client can also be extended to support additional features. On Windows OS, the 1E Client is installed as a service, with a small footprint.

The 1E Client for Linux supports the following architectures:

  • Linux variations on Intel 64-bit platforms

1E Client packages for Linux are included in the non-Windows zip available for download from the 1E Support Portal.

1E Client supports only Tachyon features on non-Windows devices.

1E Client 8.1 is not available for Solaris, please use 1E Client 5.2 instead.

The 1E Client 5.2 for Solaris supports for the following architectures:

  • Solaris on Intel 64-bit and SPARC platforms

1E Client 5.2 package for Solaris is included in the non-Windows zip available for download from the 1E Support Portal.

1E Client supports only Tachyon features on non-Windows devices.

Tachyon Activity Record feature

Tachyon clients capture certain types of event data in a local database (Persistent Storage) so that Tachyon 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.

System status bar and notification area

Tachyon includes a system status bar that displays the number of Tachyon instructions in progress and current and historical connectivity information for the total number of devices connected to Tachyon.

The notification area provides information on the logged on user or administrator and access to their notifications.

Tachyon integration

Tachyon can integrate with 3rd party products. It integrates seamlessly with Microsoft System Center Configuration Manager, it can use 1E Nomad to add content download capabilities, provides a fully-featured consumer API and can even be used as a response delivery mechanism by 3rd party applications.

Consumer management

Tachyon provides a dedicated page where the 3rd party consumers can be enabled and managed by Tachyon Consumer Administrators, as described in the Tachyon Platform - Consumers page.

Microsoft System Center Configuration Manager console integration

Configuration Manager users can use all the features of Tachyon from within the Configuration Manager console.

  • Run questions and actions that target the devices in Configuration Manager collections.

Tachyon client integration with 1E Nomad to enable efficient download of content

Tachyon can leverage the features of the industry-respected 1E Nomad to enable content to be downloaded to the Tachyon client device. Using 1E Nomad provides the following benefits:

  • Significantly reduces the bandwidth required for delivering software

  • Small offices or sites connected via poor network links can receive software updates more reliably

  • Reduces the need for large numbers of Configuration Manager servers

  • Faster Configuration Manager implementations because fewer servers are required

  • Distribute software to home, mobile, and remote office users

  • Low cost – easy to deploy

  • No new infrastructure or skills required

  • Reduces software distribution costs

The feature is a set-and-forget option on the Tachyon client. By default it is enabled and means that Tachyon will automatically use Nomad to download content if it is installed on the Tachyon client device (Nomad is currently supported on Windows devices only).

Tachyon consumer API

Tachyon implements a complete API for controlling the questions, answers, responses and workflows that implement the Tachyon features for third-party applications including ServiceNow.

The Tachyon API feature includes:

  • Consumer API versioning

  • Improved version and error reporting support in Consumer API

  • Extended RBAC API extensions for consumers

Tachyon can offload responses directly to 3rd party applications

Tachyon can be used as the means to gather data for 3rd party applications. Using its fast response time to gather the data it can then be configured to pass the data on without storing it locally. The offloading is configured for each consumer on the Consumers page, please refer to the Tachyon Platform - Consumers page. To use this feature the consumer must be configured to use the offloaded responses data.
