Configurable options for MathExpressions.

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as cloudwatch from '@aws-cdk/aws-cloudwatch';
import * as cdk from '@aws-cdk/core';
const mathExpressionOptions: cloudwatch.MathExpressionOptions = {
  color: 'color',
  label: 'label',
  period: cdk.Duration.minutes(30),
  searchAccount: 'searchAccount',
  searchRegion: 'searchRegion',
};

Properties

NameTypeDescription
color?stringColor for this metric when added to a Graph in a Dashboard.
label?stringLabel for this expression when added to a Graph in a Dashboard.
period?DurationThe period over which the expression's statistics are applied.
searchAccount?stringAccount to evaluate search expressions within.
searchRegion?stringRegion to evaluate search expressions within.

color?

Type: string (optional, default: Automatic color)

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

label?

Type: string (optional, default: Expression value is used as label)

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

If this expression evaluates to more than one time series (for example, through the use of METRICS() or SEARCH() expressions), each time series will appear in the graph using a combination of the expression label and the individual metric label. Specify the empty string ('') to suppress the expression label and only keep the metric label.

You can use dynamic labels to show summary information about the 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. If the math expression produces more than one time series, the maximum will be shown for each individual time series produce by this math expression.

period?

Type: Duration (optional, default: Duration.minutes(5))

The period over which the expression's statistics are applied.

This period overrides all periods in the metrics used in this math expression.

searchAccount?

Type: string (optional, default: Deployment account.)

Account to evaluate search expressions within.

Specifying a searchAccount has no effect to the account used for metrics within the expression (passed via usingMetrics).

searchRegion?

Type: string (optional, default: Deployment region.)

Region to evaluate search expressions within.

Specifying a searchRegion has no effect to the region used for metrics within the expression (passed via usingMetrics).
