Dashboards
Dashboards are individual websites created with Universal Dashboard. You can define settings for a dashboard and start and stop the dashboard from within the Universal administrative interface.
Adding a Dashboard
Dashboards can be added to Universal using the Add Dashboard button from the Dashboard / Dashboards page.
Name
Name is displayed throughout the UI and returned from the Universal cmdlets.
Base URL
The base URL is the URL that you will access to view this dashboard. This URL needs to be unique within this instance. You can specify the / root URL if you wish. You will have to visit /admin to login to the administrative page if you set the dashboard to the root URL.
File Name
The full file name to the dashboard file. This file needs to return a dashboard using New-UDDashboard.
Framework
The framework that the dashboard was designed for. By default, Universal Dashboard v2.9 and v3.0 are supported.
Environment
The environment to run the dashboard within.
Auth
Enables authentication for the dashboard.
Role
Defines the role that is required to access the dashboard.
AutoStart
Determines whether the dashboard should start (or restart) when the server starts or changes are made to the dashboard files.
Starting and Stopping Dashboards
Similar to jobs, dashboards run in separate PowerShell processes. You can start and stop a dashboard process by clicking the Start or Stop button from the Dashboards page.
Viewing Diagnostic Information
You can view diagnostic information for a dashboard by clicking the Info button on the Dashboards page. This will show your start information for the dashboard as well as any error that were encountered when starting the dashboard.
Viewing the Dashboard
You can view the dashboard by clicking the View button. This will take you to the Base URL for the dashboard.
Executing Commands with the Dashboard
On the dashboard information page, click on the Console tab to view the UD console. The console allows you to run scripts from within the UD runspace so you can better debug the state of your script. You can evaluate variables and run commands that are available to the dashboard. You will be running in the context of your user in regards to the runspace but the process will be running as the service account user.
Adding Custom Component Libraries
Custom component libraries provide additional components to dashboards. There are five built in component libraries that are not automatically imported into your dashboards.
UniversalDashboard.Charts
UniversalDashboard.Map
UniversalDashboard.CodeEditor
UniversalDashboard.Style
UniversalDashboard.Editor
To add these components to your dashboard, you can use the dashboard UI.
Click the info button on the dashboard page.
Next, click the components button in the top right of your dashboard.
Finally, check the component library you'd like added to your dashboard.
You can also add component libraries directly to your dashboards.ps1 script within the .unversal folder or when using single-file hosting and configuration.

Persistent Runspaces
Persistent runspaces allow you to maintain runspace state within your dashboard endpoints. This is important for users that perform some sort of initialization within their endpoints that they do not want to execute on subsequent calls.
By default, runspaces will be reset after each execution. This will cause variables, modules and functions defined during the execution of an endpoint.
To enable persistent runspaces, you will need to configure an environment for your API. Set the -PersistentRunspace parameter to enable this feature. This is configured in the environments.ps1 script.

New-PSUEnvironment -Name 'Env' -Path 'powershell.exe' -PersistentRunspace

You will need to ensure that the environment is used by the dashboard.
Automatically Granting App Tokens
You can automatically grant app tokens to users that visit dashboards. This is useful if you want to invoke the management API for PowerShell Universal from within a dashboard. Your dashboard will need to have authentication enabled and you will have to use the -GrantAppToken switch parameter on New-PSUDashboard.
1
New-PSUDashboard -Name 'Dashboard' -BaseUrl '/' -Framework "UniversalDashboard:Latest" -Authenticated -GrantAppToken
Copied!
From within your dashboard, you can now invoke the management API without having to worry about app token management. The API will be invoked in the context of the user that is visiting the dashboard.

Disable Error Toasts
By default, dashboards will display a toast message when an error is generated within an endpoint script. To avoid this behavior, you can use the -DisableErrorToast parameter of New-UDDashboard

New-PSUDashboard -Name 'Dashboard' -BaseUrl '/' -Framework "UniversalDashboard:Latest" -Authenticated -DisableErrorToast
