Scaling Events¶

Use this query to inspect scale-out and scale-in related system signals for KEDA and platform scaling decisions.

Data Source¶

Query Pipeline¶

flowchart LR
    A[Filter by app] --> B[Filter scale terms] --> C[Project scale context] --> D[Sort by time]

Query¶

let AppName = "my-container-app";
ContainerAppSystemLogs_CL
| where ContainerAppName_s == AppName
| where Log_s has_any ("scale", "keda", "replica", "autoscale", "trigger")
| project TimeGenerated, RevisionName_s, ReplicaName_s, Reason_s, Log_s
| order by TimeGenerated desc

Example Output¶

Interpretation Notes¶

• Pair this with load metrics to evaluate scaling lag.
• Frequent scale oscillation indicates threshold or stabilization tuning needs.
• Normal pattern: predictable scale reactions during known traffic peaks.

Limitations¶

• Text terms may vary by runtime platform version.
• Does not directly expose source metric values for all triggers.
