Aspire can bring Java and Rust services into one local development workflow and display their OpenTelemetry data in its dashboard. But the dashboard is a local viewer, not a complete production monitoring backend. Your services still need suitable instrumentation and OTLP export, and production typically needs an environment-appropriate collector or monitoring service.
What Aspire can replace—and what it cannot
Aspire is a code-first orchestration and observability layer. Its AppHost can organize and run application resources, while its dashboard lets developers inspect telemetry during local development. Those capabilities can simplify a local workflow that might otherwise involve separate launch and viewing tools. Microsoft’s Aspire overview lists Java and Rust among supported workloads.
That is different from replacing a monitoring stack that collects, stores, queries, visualizes, and alerts on production telemetry. Aspire’s dashboard is documented as a local OpenTelemetry viewer; deployment guidance instead calls for sending telemetry to an endpoint appropriate to the environment, such as a collector or monitoring service. Aspire dashboard documentation and Aspire telemetry guidance describe the relevant boundaries.
Can Aspire collect telemetry from Java and Rust?
Yes, provided the applications are instrumented and export telemetry over OTLP. Adding a Java or Rust resource to an AppHost helps with orchestration; it does not automatically instrument every framework, library, runtime metric, or application-specific event. Decide which logs, traces, and metrics matter, then verify that the code and libraries emit them and that an exporter sends them to the intended endpoint.

For useful distributed traces, instrumentation must cover the relevant incoming handlers and outgoing clients, and trace context must propagate across the calls being investigated. Otherwise, a dashboard may show only part of a request’s journey.
Java
The Aspire Community Toolkit’s Java integration supports executable and container resources. Its guide covers Maven and Gradle wrapper workflows as well as running an existing JAR, and documents optional configuration of the OpenTelemetry Java agent through JAVA_TOOL_OPTIONS. You still need a JDK and, depending on how you launch the application, the relevant Maven or Gradle wrapper. See Get started with Java and Aspire for the integration’s setup details.

Rust
The Rust Community Toolkit integration can run applications through Cargo or Bacon alongside other AppHost resources. Its documented capabilities include endpoints, service discovery, health checks, environment configuration, OpenTelemetry export, and Dockerfile publishing support. Cargo is required; Bacon is needed for the Bacon-specific path. See Get started with the Rust integration.
Do you still need Grafana or another monitoring backend?
Keep a separate backend if you need production collection, retention, querying, dashboards, alerting, or operational access controls that the local Aspire dashboard is not intended to provide. Aspire can participate in that architecture by helping run services and by providing a local place to inspect OTLP telemetry; it does not make the production backend unnecessary.

You can also use the standalone Aspire dashboard to receive OTLP data without an AppHost. That can fit a workflow where another tool manages the services, although you give up AppHost resource lifecycle controls. Details are in the standalone dashboard documentation.
How to decide for your team
| Question | Aspire can help with | What to verify separately |
|---|---|---|
| Where will you use it? | Local development orchestration and telemetry inspection. | Whether staging and production have an appropriate collector or monitoring service. |
| What work must be done? | Starting and coordinating application resources; viewing exported telemetry locally. | Collection, storage, querying, dashboards, and alerting at the scale and duration you require. |
| Is telemetry complete? | Providing a common local view of data that reaches the dashboard. | Whether each Java and Rust framework, library, and service emits the required logs, traces, and metrics, with trace context propagated across relevant calls. |
| Can the team operate it safely? | Offering a dashboard for local inspection. | Production authentication, access, sensitive-data controls, retention, and team workflows. |
| Will it reduce cost or complexity? | It may consolidate parts of a local workflow. | Measure the setup and maintenance trade-offs in your own environment; the cited documentation provides no quantified savings comparison. |
Version note: what “13.6” establishes
The available official release notes document Aspire 13.0, dated November 11, 2025, and state that it requires the .NET 10 SDK or later. They do not establish a distinct Aspire 13.6 feature set or confirm whether Java and Rust integration behavior changed in that version. Check the release notes and the versions of the Aspire CLI and integration packages you actually use before relying on a version-specific behavior. See What’s new in Aspire 13.

Protect telemetry and dashboard access
Telemetry can reveal resource configuration, secrets, logs, and sensitive runtime details. Treat dashboard access and OTLP endpoints accordingly: limit access to the people and environments that need it, and avoid exposing sensitive values in telemetry. Aspire documents these risks in its dashboard security considerations.
