MetricProps

class aws_cdk.aws_cloudwatch.MetricProps(*, account=None, color=None, dimensions_map=None, label=None, period=None, region=None, statistic=None, unit=None, metric_name, namespace)

Bases: CommonMetricOptions

Properties for a metric.

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_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. Use the aws_cloudwatch.Stats helper class to construct valid input strings. Can be one of the following: - “Minimum” | “min” - “Maximum” | “max” - “Average” | “avg” - “Sum” | “sum” - “SampleCount | “n” - “pNN.NN” - “tmNN.NN” | “tm(NN.NN%:NN.NN%)” - “iqm” - “wmNN.NN” | “wm(NN.NN%:NN.NN%)” - “tcNN.NN” | “tc(NN.NN%:NN.NN%)” - “tsNN.NN” | “ts(NN.NN%:NN.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
metric_name (str) – Name of the metric.
namespace (str) – Namespace of the metric.

Example:

import aws_cdk.aws_cloudwatch as cloudwatch


metric = cloudwatch.Metric(
    namespace="MyNamespace",
    metric_name="MyMetric",
    dimensions_map={"MyDimension": "MyDimensionValue"}
)
alarm = cloudwatch.Alarm(self, "MyAlarm",
    metric=metric,
    threshold=100,
    evaluation_periods=3,
    datapoints_to_alarm=2
)

topic_rule = iot.TopicRule(self, "TopicRule",
    sql=iot.IotSql.from_string_as_ver20160323("SELECT topic(2) as device_id FROM 'device/+/data'"),
    actions=[
        actions.CloudWatchSetAlarmStateAction(alarm,
            reason="AWS Iot Rule action is triggered",
            alarm_state_to_set=cloudwatch.AlarmState.ALARM
        )
    ]

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_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

metric_name: Name of the metric.

namespace: Namespace of the metric.

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.

Use the aws_cloudwatch.Stats helper class to construct valid input strings.

Can be one of the following:

“Minimum” | “min”
“Maximum” | “max”
“Average” | “avg”
“Sum” | “sum”
“SampleCount | “n”
“pNN.NN”
“tmNN.NN” | “tm(NN.NN%:NN.NN%)”
“iqm”
“wmNN.NN” | “wm(NN.NN%:NN.NN%)”
“tcNN.NN” | “tc(NN.NN%:NN.NN%)”
“tsNN.NN” | “ts(NN.NN%:NN.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
