Come creare un modello di rilevamento delle anomalie

L’esempio put-anomaly-detector seguente crea un modello di rilevamento delle anomalie per un parametro CloudWatch.

aws cloudwatch put-anomaly-detector \
    --namespace AWS/Logs \
    --metric-name IncomingBytes \
    --stat SampleCount

Questo comando non produce alcun output.

Per ulteriori informazioni, consulta Utilizzo del rilevamento di anomalie CloudWatch nella Guida per l’utente di Amazon CloudWatch.
