The Devices page provides a list of all devices visible to Tachyon Experience. You can see all of their Experience, Stability, Performance and Responsiveness statistics and sort them accordingly. 

On this page:

The Devices page

The Devices page allows you to view detailed information for each device in your environment by drilling into a device. From here, you can:

  • Select two devices and use Device Comparison to compare their settings
  • Use the Scatter Chart to plot the displayed devices on a two-dimensional graph with configurable axes
  • Select one or more devices and use Explore to set them as the scope for an explorer instruction
  • You can display the Device View for a selected device by clicking on its link in the FQDN column.

Device Comparison

Selecting two devices from the Devices table enables the Device Comparison button. Clicking on the button displays the Device Comparison popup.

The data for the comparison is fetched in real-time from both the selected devices.

The details for the comparison are displayed in a table, with the parameter headings on the left-hand column and then one column per-device showing the values corresponding to the parameters.

Each column heading for the devices contains a checkbox, that can be used to select the device as the scope for an Explorer session by clicking on the Explore button. The FQDN name for each device is a link that can be used to display the Device View for that device.

The information in the table is grouped into 7 collapsible category headings: Device, Operating System, Usage, Hardware, Software, Services and Processes.

Each row where there is a difference is highlighted in yellow and where the information is the same in white. You can select to focus on only the differences by switching the Only different values toggle to on.

Scatter Chart

Clicking on the Scatter Chart button in the Devices page displays the Scatter Chart popup. The devices from the current view are plotted as points on a graph according to their Responsiveness scores on the X-axis and Performance scores on the Y-axis.

You can hover over a point on the graph to view its details.

The parameters plotted on the axis can be changed using the axis dropdowns. The parameter you want to plot is selected from a list that can be filtered by typing text into the search field. The picture opposite shows the Memory: Hard page faults parameter selected.

You must click the Apply button to re-plot the graph according to the new selection.

Both axes can be changed. The picture opposite shows the device Memory: Hard page faults plotted against the Memory: Page file usage scores.

Explore Button

If the account you are viewing Tachyon Experience with has at least the Global Questioner role, you will also see an Explore button.  Clicking this button will launch Tachyon Explorer.

The coverage will be set to the device you were viewing in Experience.

The Device View

Clicking on one of the links in the FQDN column of the Devices page displays the Device View for the selected device. The aim of the Device View is to provide a combined overview of all the information known about a device, along with the ability to retrieve information about the device in real-time. There are a number of tabs available in the Device View, but the Experience tab is specific to the Experience application.

The Device View Experience tab

When displaying the Device view from an Experience page the view defaults to the Experience tab. The Experience tab contains information derived from and useful for Tachyon Experience. It contains the following panels:

Metrics panel

This panel shows the current gradings for all the Metrics that are measured by Tachyon Experience.

Only the current gradings can be seen here, there is no ability to look at the history information in this panel. 

Metrics with a Very Poor grading are marked by lines in red with an exclamation mark.

Trends panel

The Trends panel shows the Metric measurements over time, making it easy to determine trends and see what else was happening on the device as an issue progressed.

Logs panel

The Logs panel shows the Windows Event Log entries for significant events.  These events are captured as they happen, the device does not wait for the daily digest to send the information to the switch.

Application Interaction panel

This panel provides a couple of charts and lists the applications that have most recently been interacted with on the device.

The Interaction Time Percent chart shows the amount of time each application on the device was interacted with as a percentage of the time for all the applications.

The Foreground Time Percent chart shows the amount of time each application spent in the foreground as a percentage of the time for all the applications.

The table lists the applications most recently interacted with on the device. The table can be sorted on each column.

ProductThe common name for the product.
ExecutableThe executable name associated with the product.
VersionThe version number for the product entry.
Interaction PercentThe percentage of time the product was interacted with out of the total time all the applications were interacted with.
Foreground PercentThe percentage of time the product spent in the foreground out of the total time all the applications spent in the foreground.
Average Interaction Minutes Per DayThe daily average number of minutes the product was interacted with.
Average Foreground Minutes Per DayThe daily average number of minutes the product spent in the foreground.
LagThe maximum lag time between interacting with the application and getting a response.

User Interaction panel

This panel provides information about the last known user for the device. 

DateThe date the interaction took place.
User NameThe domain user name who performed the interaction.
Connected FromThe device the user connected to the device from. 
Logon MinutesThe number of minutes the specified user has been logged on for.
Present MinutesThe number of minutes the specified user was counted as present on the device while they were logged on.
Interaction MinutesThe number of minutes the specified user interacted with the device.
User Wait TimeThe amount of wait time in minutes the user spent waiting for a response from an application.

Additional Device View tabs

In addition to the Experience tab, there are a number of other tabs, each corresponding to an app, feature or data set implemented in Tachyon Platform 8.0

The Overview and 1E Client tabs are always present in the Device View. Other tabs are visible if an app has been installed and is licensed.

Each tab has one or more panels with tiles populated with data from various sources, some by instructions that are run instantly, with results cached for 3 minutes. An appropriate error message is displayed instead of a tile in the following circumstances:

  • If the device is offline, as indicated by the color of the icon in the top left
  • The user does not have at least Viewer permission to view use the license the tab or panel
  • The user does not have questioner permission to run the instruction
  • An instruction has not been uploaded.

The Device View tabs and panels page lists the names of tabs and their panels, and a description of each tile indicating how the tile is populated.

Download activity and status for the device. Whenever you click on an FQDN on any of the Nomad pages then the Device View will be displayed with the Downloads tab selected.Data from Content Distribution.


Content Titles on the selected device, the default view is from All Sources, All Types and All Status.

You may see a difference in the number of items in a device’s Nomad cache versus that displayed in the Nomad app Device View. This is because if downloaded content has been deleted from Configuration Manager, the content titles cannot be resolved in the Nomad app and are not displayed. This is under consideration for re-design and may be revised in future versions of Nomad.

Virtual Memory Usage KB
Processor Time Seconds
Each instance of the executable will burn processor time. This column gives the average of the total time consumed by each process instance per second. Each instance uses the sum of all time used by each core in parallel. Therefore, it is possible to see more seconds here than in a day (usually 60 x 60 x 24 = 86400) for the whole column, if your system is working extremely hard 24x7. The theoretical maximum would be somewhere near number of cores  seconds per day . Hence, 'Processor Time' rather than 'Human Time'
Processor Time %

This is an easier notion than Processor Time Seconds. This is the average of the processor consumption of each instance. Each instance of this process will have caused different percentages of compute resource in all the processors and cores to be used over time (unless they have specifically requested certain core affinity). For each minute each process is running, a profile of the usage is built for the whole day. This value is the average of all of those samples. There is no way to work out, for any one of the process instances involved, how long any particular instance was running for. This could indicate a process that is going wild with resources, but it would take more investigation on the device to discover for how long this is happening. It is perfectly possible to see all the values in this column adding up to more than 100% as the processes were not necessarily running at the same time.

Responsiveness Impact %

An indicator of how reactive a process is to activity by other processes on the device. Typically, anti-virus products watch and respond to potentially suspicious activity such as increased network traffic. Anti-virus products will differ in their impact on the overall performance of a device.

Responsiveness Impact % is used to indicate how sensitive a process that appears to be to the use of system resources by other processes on a device. For example Security Protection software present on a device may reveal a spike in its activity whenever a new process is started on that device. This would typically be because the Security Protection software may wish to ensure that the new process starting on the device is present in a security white-list. Other software may also react to activity by other processes and by reacting they impact system resource uses, thereby adversely affect the user's experience. So it is useful to be able to identity software with the highest Responsiveness Impact on a device and potentially investigate further.

Responsiveness Impact % represents the proportion of the increased CPU activity detected by the 1E Client as a result of performing a set of operating system level operations that can be attributed to a given running process. Examples of these would be Windows registry and resource creation operations.

It is reported as a percentage to normalize results across devices that offer a range of computing power.

For example if software.exe on a device is attributed a Responsiveness Impact of 53% this means that more than half of the spike in CPU usage caused by software monitoring activity on that device can be attributed to software.
