Statistic¶

class aws_cdk.aws_cloudwatch.Statistic(value)¶

Bases: enum.Enum

Statistic to use over the aggregation period.

ExampleMetadata: infused

Example:

import aws_cdk.aws_cloudwatch as cloudwatch
# delivery_stream: firehose.DeliveryStream


# Alarm that triggers when the per-second average of incoming bytes exceeds 90% of the current service limit
incoming_bytes_percent_of_limit = cloudwatch.MathExpression(
    expression="incomingBytes / 300 / bytePerSecLimit",
    using_metrics={
        "incoming_bytes": delivery_stream.metric_incoming_bytes(statistic=cloudwatch.Statistic.SUM),
        "byte_per_sec_limit": delivery_stream.metric("BytesPerSecondLimit")
    }
)

cloudwatch.Alarm(self, "Alarm",
    metric=incoming_bytes_percent_of_limit,
    threshold=0.9,
    evaluation_periods=3
)
