MetricOptions

class aws_cdk.aws_cloudwatch.MetricOptions(*, account=None, color=None, dimensions=None, dimensions_map=None, label=None, period=None, region=None, statistic=None, unit=None)

Bases: CommonMetricOptions

Properties of a metric that can be changed.

Parameters:

  • account (Optional[str]) – Account which this metric comes from. Default: - Deployment account.

  • color (Optional[str]) – The hex color code, prefixed with ‘#’ (e.g. ‘#00ff00’), to use when this metric is rendered on a graph. The Color class has a set of standard colors that can be used here. Default: - Automatic color

  • dimensions (Optional[Mapping[str, Any]]) – (deprecated) Dimensions of the metric. Default: - No dimensions.

  • dimensions_map (Optional[Mapping[str, str]]) – Dimensions of the metric. Default: - No dimensions.

  • label (Optional[str]) – Label for this metric when added to a Graph in a Dashboard. You can use dynamic labels to show summary information about the entire displayed time series in the legend. For example, if you use:: [max: ${MAX}] MyMetric As the metric label, the maximum value in the visible range will be shown next to the time series name in the graph’s legend. Default: - No label

  • period (Optional[Duration]) – The period over which the specified statistic is applied. Default: Duration.minutes(5)

  • region (Optional[str]) – Region which this metric comes from. Default: - Deployment region.

  • statistic (Optional[str]) – What function to use for aggregating. Can be one of the following: - “Minimum” | “min” - “Maximum” | “max” - “Average” | “avg” - “Sum” | “sum” - “SampleCount | “n” - “pNN.NN” Default: Average

  • unit (Optional[Unit]) – Unit used to filter the metric stream. Only refer to datums emitted to the metric stream with the given unit and ignore all others. Only useful when datums are being emitted to the same metric stream under different units. The default is to use all matric datums in the stream, regardless of unit, which is recommended in nearly all cases. CloudWatch does not honor this property for graphs. Default: - All metric datums in the given metric stream

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

account

Account which this metric comes from.

Default:

  • Deployment account.

color

The hex color code, prefixed with ‘#’ (e.g. ‘#00ff00’), to use when this metric is rendered on a graph. The Color class has a set of standard colors that can be used here.

Default:

  • Automatic color

dimensions

(deprecated) Dimensions of the metric.

Default:

  • No dimensions.

Deprecated:

Use ‘dimensionsMap’ instead.

Stability:

deprecated

dimensions_map

Dimensions of the metric.

Default:

  • No dimensions.

label

Label for this metric when added to a Graph in a Dashboard.

You can use dynamic labels to show summary information about the entire displayed time series in the legend. For example, if you use:

[max: ${MAX}] MyMetric

As the metric label, the maximum value in the visible range will be shown next to the time series name in the graph’s legend.

Default:

  • No label

period

The period over which the specified statistic is applied.

Default:

Duration.minutes(5)

region

Region which this metric comes from.

Default:

  • Deployment region.

statistic

What function to use for aggregating.

Can be one of the following:

  • “Minimum” | “min”

  • “Maximum” | “max”

  • “Average” | “avg”

  • “Sum” | “sum”

  • “SampleCount | “n”

  • “pNN.NN”

Default:

Average

unit

Unit used to filter the metric stream.

Only refer to datums emitted to the metric stream with the given unit and ignore all others. Only useful when datums are being emitted to the same metric stream under different units.

The default is to use all matric datums in the stream, regardless of unit, which is recommended in nearly all cases.

CloudWatch does not honor this property for graphs.

Default:

  • All metric datums in the given metric stream
