CloudWatch ejemplos que utilizan AWS SDK for .NET

Los siguientes ejemplos de código muestran cómo realizar acciones e implementar escenarios comunes mediante el uso del AWS SDK for .NET with CloudWatch.

Las acciones son extractos de código de programas más grandes y deben ejecutarse en contexto. Mientras las acciones muestran cómo llamar a las funciones de servicio individuales, es posible ver las acciones en contexto en los escenarios relacionados y en los ejemplos entre servicios.

Los escenarios son ejemplos de código que muestran cómo llevar a cabo una tarea específica llamando a varias funciones dentro del mismo servicio.

Cada ejemplo incluye un enlace a GitHub, donde puede encontrar instrucciones sobre cómo configurar y ejecutar el código en su contexto.

Escenarios

Primeros pasos para usar las métricas, los paneles y las alarmas

En el siguiente ejemplo de código, se muestra cómo:

• Enumera los espacios de CloudWatch nombres y las métricas.

• Obtener estadísticas para una métrica y para la facturación estimada.

• Crear y actualizar un panel.

• Crear y agregar datos a una métrica.

• Crear y activar una alarma y, a continuación, consultar el historial de alarmas.

• Crear un detector de anomalías.

• Realice una imagen métrica y, luego, limpie los recursos.

    Before running this .NET code example, set up your development environment, including your credentials.

    To enable billing metrics and statistics for this example, make sure billing alerts are enabled for your account:
    https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/monitor_estimated_charges_with_cloudwatch.html#turning_on_billing_metrics

    This .NET example performs the following tasks:
        1. List and select a CloudWatch namespace.
        2. List and select a CloudWatch metric.
        3. Get statistics for a CloudWatch metric.
        4. Get estimated billing statistics for the last week.
        5. Create a new CloudWatch dashboard with two metrics.
        6. List current CloudWatch dashboards.
        7. Create a CloudWatch custom metric and add metric data.
        8. Add the custom metric to the dashboard.
        9. Create a CloudWatch alarm for the custom metric.
       10. Describe current CloudWatch alarms.
       11. Get recent data for the custom metric.
       12. Add data to the custom metric to trigger the alarm.
       13. Wait for an alarm state.
       14. Get history for the CloudWatch alarm.
       15. Add an anomaly detector.
       16. Describe current anomaly detectors.
       17. Get and display a metric image.
       18. Clean up resources.
