SearchExpressionProps Struct ​

Properties for a SearchExpression.

Example ​

ts
const cpuUtilization = new cloudwatch.SearchExpression({
  expression: "SEARCH('{AWS/EC2,InstanceId} MetricName=\"CPUUtilization\"', 'Average', 900)",
  label: 'EC2 CPU Utilization',
  color: '#ff7f0e',
});

Properties ​

coloroptionalstringcoloroptionalstrcoloroptionalStringColoroptionalstringColoroptional*string#
Color for the metric produced by the search expression.

Default: Automatically assigned.

If the search expression produces more than one time series, the color is assigned to the first one. Other metrics are assigned colors automatically.

expressionstringexpressionstrexpressionStringExpressionstringExpression*stringrequired#
The search expression defining the metrics to be retrieved.
notes

A search expression cannot be used within an Alarm.

A search expression allows you to retrieve and graph multiple related metrics in a single statement. It can return up to 500 time series.

Examples:

  • SEARCH('{AWS/EC2,InstanceId} CPUUtilization', 'Average', 300)
  • SEARCH('{AWS/ApplicationELB,LoadBalancer} RequestCount', 'Sum', 60)
  • SEARCH('{MyNamespace,ServiceName} Errors', 'Sum')

For more information about search expression syntax, see: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/search-expression-syntax.html

labeloptionalstringlabeloptionalstrlabeloptionalStringLabeloptionalstringLabeloptional*string#
Label for this search expression when added to a Graph in a Dashboard.

Default: No label.

notes

If this expression evaluates to more than one time series, 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 search expression produces more than one time series, the maximum will be shown for each individual time series produce by this search expression.

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

This period overrides the period defined within the search expression.
