Dapr Sidecar Logs¶

Use this query when Dapr sidecar startup, component loading, or invocation behaviors are failing.

Data Source¶

Query Pipeline¶

flowchart LR
    A[Filter by app] --> B[Filter Dapr and component terms] --> C[Project runtime context] --> D[Sort by time]

Query¶

let AppName = "my-container-app";
ContainerAppConsoleLogs_CL
| where ContainerAppName_s == AppName
| where Log_s has_any ("dapr", "sidecar", "component", "pubsub", "state", "invoke")
| project TimeGenerated, RevisionName_s, Log_s
| order by TimeGenerated desc

Example Output¶

Interpretation Notes¶

• Component initialization errors usually include metadata or auth hints.
• Sidecar health failures often appear before app-level request failures.
• Normal pattern: startup logs then low-error steady-state operation.

Limitations¶

• Requires Dapr logs to be routed into console log stream.
• May include app logs that mention dapr without sidecar failure.
