Restate’s execution journal gives you complete visibility into what your agents are doing. Every LLM call, tool execution, routing decision, and state change is recorded and inspectable.

​
Restate UI

The Restate UI (http://localhost:9070) provides a live view of your agent executions:
  • Invocations list: See all running, suspended, and completed agent invocations
  • Journal view: Inspect the step-by-step execution of any agent, including inputs, outputs, and timings
  • State view: View the current K/V state of Virtual Objects (sessions, agent state)
  • Nested calls: For multi-agent systems, trace the complete call chain across services in a single view

The state tab shows what is stored in each Virtual Object:

​
Tracing

Restate exports OpenTelemetry traces for all agent executions. Connect to your existing observability stack:
  • LangFuse, Jaeger, or any OpenTelemetry-compatible backend
  • Each durable step appears as a span in the trace
  • Cross-service calls (remote agents) are connected in a single distributed trace

​
Cancelling and killing agents

You can manage stuck or runaway agents:
  • Cancel: Gracefully stops an invocation, allowing compensation/cleanup logic to run
  • Kill: Immediately terminates an invocation without cleanup
Via the Restate UI:

Or via the CLI. This is critical for long-running agents that may get stuck in loops or consume excessive resources.
