API Logs

The API Logs page shows a structured log of every Dapr API call made by or to an App ID in your project. Each entry captures:

• App ID — the workload that made or received the call.
• API — the Dapr building block invoked (state, pub/sub, service invocation, etc.).
• Method and status code.
• Latency in milliseconds.
• Timestamp.

Filtering

Filter by App ID, API type, status (success / error), or time range. Use the status filter to surface all failed calls during an incident window, then cross-reference with Metrics to see the error-rate spike and App Graphs for topology context.

LLM calls

For AI agents, API Logs captures LLM calls (via the Conversation API) including model, token counts, and latency — useful for cost attribution and debugging slow or truncated responses. Combine with the Agents view to correlate per-session tool calls with LLM invocations.
