Welcome to Connext Studio (Experimental Release)
Connext Studio brings Connext system insight directly into your IDE by helping you inspect, visualize, and debug Connext applications during development. You can interact with Connext Studio through the Studio UI or through chat interfaces, including Connext Chat and GitHub Copilot Chat in Ask mode or Agent mode. The Studio UI is organized around two basic concepts: Data Sources and Views. Data Sources provide information about your running DDS system, which Connext Studio uses to build an in-memory system model. Views present that model in useful ways, from predefined topology view to custom visualizations of Topic data. With Connext AI features, you can also describe the View you want in natural language and let Connext Studio generate it for you. RequirementsTo use Connext Studio, you need the following:
In addition, some chat commands may require additional third-party extensions. For example, the [Optional] Connext AI-Powered FeaturesConnext AI features are optional. The core Connext Studio can be used without AI. The optional Connext AI features included with Connext Studio are:
Using the Connext Studio UIStudio PanelTo open the Studio panel, click the Studio icon on the left sidebar, as shown below: Login and Welcome ScreensLogin with your RTI account is required to use Connext Studio. (See the Requirements section above to get an RTI account.) If you are not logged into Connext Studio, a Login Screen is shown.
Once logged in, Connext Studio presents an on-boarding Welcome Screen for you to select the installation of Connext you’d like Studio to use. The selected installation is the combination of the Connext version and RTI Architecture that Studio will use to run RTI DDS Spy and other Connext tools locally on your machine. If you do not have Connext Professional or Connext Drive installed already, the Welcome Screen helps you download and install an evaluation version of Connext, and helps you install an evaluator license file.
The Connext Studio Settings pane described under the Account & Support section below allows you to restart the on-boarding Welcome Screen at any time. Data SourcesData Sources are inputs you connect, which Connext Studio uses to build a model (i.e., an in-memory representation) of your Connext system. You can connect more than one data source, which may help Connext Studio build a more complete model of your system than if it had access to only one source. The supported Data Sources include: You can also connect data sources from the cloud. If you have a Connext Cloud account, see Connext Cloud Integration below. To connect a Data Source, click the + icon in the Data Sources pane:
After clicking the + button, select the desired data source from the list and follow the on-screen prompts:
Data Source Capabilities
RTI DDS SpyThe RTI DDS Spy Data Source connects to a live Connext system using RTI DDS Spy. Connext Studio runs DDS Spy locally and uses the discovered information to build a model of your system. Use this Data Source when you want Connext Studio to discover Hosts, Applications, Domain Participants, Topics, Publishers, Subscribers, DataWriters, DataReaders, and QoS information directly from a running development system. RTI recommends using DDS Spy from Connext 7.7 or later with Connext Studio. This version provides more complete discovery information, including matching QoS information, type information for discovered endpoints, and the participant metadata used by vulnerability detection (only in Connext 7.7 support patch and later). This Data Source requires a local Connext installation because Connext Studio uses the DDS Spy executable from the selected Connext installation. Collector ServiceThe Collector Service Data Source connects to remote debugging data made available by RTI Collector Service. Connext Studio connects to Collector Service through a WebSocket endpoint and uses the discovery-related telemetry data published by Collector Service to build a model of your Connext system. Use this Data Source when your system is configured to forward remote debugging data through Collector Service. Connext Studio can use this source by itself or together with other Data Sources, such as RTI DDS Spy, to build a more complete model of your Connext system. The Collector Service configuration required by Connext Studio is the same configuration used by RTI Admin Console remote debugging. The Collector Service instance must be configured with a WebSocket exporter endpoint. Depending on your security configuration, the connection uses either a non-secure WebSocket endpoint or a secure WebSocket endpoint. For more information about configuring Collector Service for remote debugging, see the RTI Admin Console Remote Debugging documentation. Note: The Collector Service Data Source only uses the remote debugging data exposed by Collector Service through its WebSocket endpoint. It does not currently provide access to telemetry stored in Prometheus, Loki, or other third-party observability backends. RTI Admin Console Discovery Export FileThe RTI Admin Console discovery export file Data Source imports a discovery snapshot previously exported from RTI Admin Console. Use this Data Source when you want to analyze a system offline, share a captured discovery view, or inspect a system without connecting Connext Studio directly to the running DDS domain. The Admin Console discovery export file provides system topology and information available through the built-in Topic endpoints, including Publication, Subscription, and Domain Participant information. This Data Source is useful when the system is no longer running, when direct network access to the DDS domain is not available, or when you want to preserve a point-in-time view of the system for later analysis. Note: You can continue to use RTI Admin Console to inspect discovery information directly. Loading an Admin Console discovery export file into Connext Studio is useful when you want to use Connext Studio capabilities on that captured system model, including AI-powered querying and analysis using Connext AI. Connext Cloud Integration (Preview)Connext Cloud integration lets you browse and connect to your Connext Cloud Databuses and Observability Services directly from Connext Studio. Connected cloud resources become regular Data Sources — a Databus becomes a DDS Spy source and an Observability Service becomes a Collector Service source — so all Studio capabilities (System Explorer, Views, AI analysis, vulnerability detection) work seamlessly with cloud-sourced data.
Cloud ViewThe Cloud View panel appears in the Studio sidebar. It displays your Connext Cloud resources organized into two groups:
Each resource displays a status indicator: Active, Creating, Connecting, Provisioning, Error, or Disabled. The view auto-refreshes every 60 seconds and can be refreshed manually using the refresh button in the view header.
Cloud LoginConnext Cloud uses the same RTI account credentials as Connext Studio. To log in to Connext Cloud, click the Log in button in the Cloud View. This opens your browser for authentication. If you are already signed into your RTI account in the browser, you will likely not be prompted for credentials again. If this is your first time using the Cloud integration, you may be asked to accept the Preview terms before proceeding. Click Continue to Preview to open the Cloud dashboard and accept the terms, then return to Studio.
Note: Connext Cloud and your RTI Account have separate login sessions. Logging out from Connext Cloud (using the logout button in the Cloud View) disconnects your cloud resources but keeps your RTI Account session active — you can continue using other Connext Studio features. To log out completely, go to Account & Support and log out from your RTI Account, which also logs you out from Connext Cloud. Connecting Cloud ResourcesOnce logged in, you can connect any active cloud resource to Connext Studio: Connecting a Databus: Click the Connect button (plug icon) next to a Databus in the Cloud View. This creates a DDS Spy data source that discovers your cloud Databus. For secure Databuses, Connext Studio automatically handles the security setup — generating keys, requesting certificates from the Cloud API, and storing the security artifacts locally. No manual security configuration is required.
Connecting an Observability Service: Click the Connect button (plug icon) next to an Observability Service. This creates a Collector Service data source that streams telemetry from your cloud observability endpoint. Disconnecting: Click the Disconnect button next to a connected resource to remove the data source connection.
Once connected, the cloud data sources appear in the Data Sources pane and contribute to the system model like any other source.
Cloud Dashboard NavigationFrom the Cloud View, you can navigate directly to the Connext Cloud dashboard:
System Explorer, Object Property and ProblemsThe System Explorer, Object Property and Connext Problems panes work together to help you navigate and inspect the model of your Connext system. The System Explorer shows the model built from the connected Data Sources. It provides a tree view that lets you browse discovered DDS entities and navigate their relationships.
The System Explorer organizes the model from different perspectives, including:
When you select an entity in the System Explorer, the Object Property pane shows the properties available for that entity. For example, selecting a DataWriter may show properties such as its name, DDS GUID, QoS policies, and other metadata discovered for that endpoint.
The information shown in the Object Property pane depends on the connected Data Sources. Clicking an entity in the System Explorer also updates the Connext Problems pane to show the problems related to that object. The Connext Problems pane reports:
An alternative way to explore the system is to use the System Visualization view, described in System Views below. The System Visualization view provides a graphical representation of the same discovered system model and lets you inspect DDS objects visually. ViewsViews are configurable outputs to visualize and summarize the model of your DDS system. You must have at least one Data Source connected to use Views.
System ViewsSystem Views group together the predefined views that focus on the topology and behavior of your Connext system. System VisualizationShows a graphical representation of the discovered Connext system. It presents information similar to the System Explorer tree view, but as a visual diagram. This view helps you understand the system topology, including Domains, Domain Participants, Topics, Publishers, Subscribers, DataWriters, DataReaders, and their relationships.
Clicking a DDS object in the System Visualization has the same effect as selecting it in the System Explorer: the Object Property pane is populated with contextual information about that object, based on the current system model, and the Connext Problems pane shows any problems related to that object. The System Visualization highlights DataWriter/DataReader match problems using colored Topic edges:
The System Visualization also surfaces known vulnerabilities on participant and application nodes. Affected nodes display a vulnerability indicator with counts aggregated by severity (Critical, High, Medium, Low) for the node and its descendants, so you can spot the most exposed parts of the system at a glance. Selecting an affected object populates the Connext Problems pane with its vulnerability details. Partition differences are not treated as QoS mismatches. They may still appear in the Connext Problems pane, but only as informational items. Security ViewsSecurity Views group together the predefined views that focus on the security posture of your Connext system, including DDS Security log events and known product vulnerabilities. Security Events ViewerShows DDS Security log events discovered by Connext Studio in a detailed, inspectable list. Use this view to review individual security events and investigate specific security-related behavior. Security Events DashboardShows a summarized dashboard of DDS Security log events discovered by Connext Studio. It displays event counts by severity, alerts and errors grouped by reporting Domain Participant and flagged Domain Participant, and security events over time. Note: Security events are detected from an RTI DDS Spy Data Source configured to use security and subscribe to the DDS Security built-in secure logging Topics. Vulnerability MonitorShows the known security vulnerabilities that affect the Connext Domain Participants discovered in your running system. The Monitor lists one entry per affected participant and vulnerability, including the participant name, the affected Connext product and version, the CVE ID, RTI ID, CVSS score, severity, and affected component. Use this view to understand which deployed participants are exposed and to prioritize remediation. The view updates as the system model changes. Records can be grouped, expanded/collapsed (show more/less), and exported to CSV.
Note: Vulnerability information is derived from RTI's published vulnerability data and is matched against the Connext product versions detected in your system model. Vulnerability detection therefore depends on Data Sources that can report participant product version and security information, such as RTI DDS Spy or an RTI Admin Console discovery export file that includes those fields. The set of vulnerabilities reported for a participant is further refined using the participant's running service, such as Persistence Service, Routing Service, or Recording Service, so that only relevant components are flagged. Vulnerability ExplorerShows a deduplicated catalog of known vulnerabilities for the Connext product versions present in your system (derived from your installed Connext versions), grouped by CVE. Unlike the Vulnerability Monitor, the Explorer is organized by unique vulnerability rather than by affected participant; each entry merges all affected product versions and includes severity, CWE, CAPEC, a description, the user impact (with and without security enabled), and recommended mitigations. Use this view to research the vulnerabilities relevant to your Connext versions independently of which participants are currently running. Entries can be filtered, expanded/collapsed, and exported to CSV.
Create Data VisualizationCreate Data Visualization allows you to visualize the samples published on a DDS Topic as a table or time chart. Click Create Data Visualization and follow the wizard to set up the visualization as desired.
Creating a Data Visualization automatically creates a subscription to the Topic of interest. AI ViewsYou can also create Views with AI. Click Create View with AI in the Views pane, and then describe a view of your system in natural language. For example, "Create a list of all the reliable DataWriters with only best effort DataReaders" or "Create a dashboard for patient ab1234 that visualizes all signals from the Vital Topic". Connext AI will generate this view based on your system and visualization description. Connext AI is also aware of known vulnerabilities affecting your system, so you can ask it to generate views that highlight or filter by vulnerable participants, components, or product versions, for example, "List all participants affected by a critical vulnerability".
AI Views are automatically saved under Your Views. After a View has been created, you can open and run it again at any time from Your Views. User-created Views can be exported and imported using the export and import buttons in the Views pane. Export a View when you want to share a custom analysis with someone else. Import a View to add a View that someone shared with you or restore one that was exported previously.
Connext AI is only required to create the View. Once the View has been generated, Connext Studio runs the generated View code directly; Connext AI is not required to execute the View. You can inspect the generated View code by clicking the code/document icon next to the View in Your Views. As an alternative to using Create View with AI in the UI, you can create a View via Connext Chat using the
Account & SupportThe Account & Support section provides access to account, configuration, documentation, and feedback actions for Connext Studio. It also allows launching RTI Launcher from the default Connext installation.
Settings PaneThe Settings pane for Connext Studio can be opened by clicking “Settings” in the Account & Support pane. This pane allows you to choose the Connext installation and architecture that will be used to launch Connext tools, like Spy. The Settings pane also allows you to restart the on-boarding Welcome Screen and access advanced extension settings.
Chat PanelTo open the Connext Chat, click the Connext AI avatar icon on the left sidebar, as shown below: And then type your question:
You can enrich your question by adding relevant files or images via the Add Context button:
Chat CommandsThis extension allows invoking pre-defined commands from the chat window by typing /<command> or clicking the / (Browse Commands) button in Connext Chat. Standalone Commands can be sent on their own, and Contextual Commands require an argument or further input. The available Standalone Commands are:
The Contextual Commands are:
The commands that start tools and generate new examples will fail if there is no default Connext installation configured (either by using the default installation directory or by setting the NDDSHOME environmental variable). includeOpenFiles and includeWorkspace commandsThe These commands do not include every matching file. Some files are intentionally excluded even if they are open in the editor or present in the workspace. In particular, the following files automatically generated by rtiddsgen are not included because they can be very large and usually add little value to the AI response while quickly consuming the available context length:
The Using Connext Studio with GitHub Copilot ChatWhen GitHub Copilot Chat is installed, Connext Studio integrates with it by default. If needed, you can disable this integration under User Account & Support → Settings -> Advanced Settings -> Connext -> GitHub Copilot Compatibility. To run Connext Studio with GitHub Copilot, you need:
Using @connextIn the GitHub Copilot Chat interface in Ask or Agent mode, simply type @connext followed by your question or command. This explicitly routes your message to the Connext Studio chat participant. Use Examples:
Once you type In GitHub Copilot Chat, Connext Studio chat commands are available using the same When GitHub Copilot Compatibility is enabled, Connext Studio also exposes additional VS Code integration points, including the Connext right-click context menu with actions such as Explain this, and support for VS Code Quick Chat. Using @connext is only necessary when you are interacting with Connext Studio from the GitHub Copilot Chat interface. Language Model ToolsWhen GitHub Copilot Compatibility is enabled, Connext Studio also exposes Language Model Tools that GitHub Copilot can use in agent mode. Language Model Tools are different from With With Language Model Tools, GitHub Copilot remains the active chat participant. Copilot may invoke a Connext Studio tool when it is useful for the task. That tool invocation sends a request to Connext Studio, Connext Studio returns the result, and Copilot uses that result to continue the Agent mode workflow. In short, Use Agent mode with Language Model Tools when you want GitHub Copilot to work on a broader coding or configuration task and use Connext Studio capabilities as needed. For example, Copilot may call Connext Studio tools to get Connext-specific guidance, inspect local Connext installations, or validate generated Connext code. The language model tools offered by Connext Studio are a superset of the tools offered by Connext MCP, therefore GitHub Copilot Agent mode in VS Code with Connext Studio installed does not need Connext MCP configured. Users outside of the GitHub Copilot + Connext Studio ecosystem can access a subset of the Connext AI language model tools through Connext MCP. Connext Studio - Available Tools
Using Tools in GitHub Copilot ChatYou can reference these tools directly in the GitHub Copilot Chat by using the # prefix followed by the tool reference name. For example:
Alternatively, GitHub Copilot will automatically invoke these tools when it determines they are relevant to your question. For instance, if you ask about Connext DDS in Agent mode, Copilot may automatically use the Ask Connext tool to provide expert-level answers. Example Usage
