Statistic

class aws_cdk.aws_cloudwatch.Statistic(value)

Bases: 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
)

Attributes

AVERAGE: The value of Sum / SampleCount during the specified period.

MAXIMUM

The highest value observed during the specified period.

You can use this value to determine high volumes of activity for your application.

MINIMUM

The lowest value observed during the specified period.

You can use this value to determine low volumes of activity for your application.

SAMPLE_COUNT: The count (number) of data points used for the statistical calculation.

SUM

All values submitted for the matching metric added together.

This statistic can be useful for determining the total volume of a metric.
