MetricFilter

Metric filters express how CloudWatch Logs would extract metric observations from ingested log events and transform them into metric data in a CloudWatch metric.

applyOnTransformedLogs

This parameter is valid only for log groups that have an active log transformer. For more information about log transformers, see PutTransformer.

If this value is true, the metric filter is applied on the transformed version of the log events instead of the original ingested log events.

Type: Boolean

Required: No

creationTime

The creation time of the metric filter, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC.

Type: Long

Valid Range: Minimum value of 0.

Required: No

emitSystemFieldDimensions

The list of system fields that are emitted as additional dimensions in the generated metrics. Returns the emitSystemFieldDimensions value if it was specified when the metric filter was created.

Type: Array of strings

Required: No

fieldSelectionCriteria

The filter expression that specifies which log events are processed by this metric filter based on system fields. Returns the fieldSelectionCriteria value if it was specified when the metric filter was created.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 2000.

Required: No

filterName

The name of the metric filter.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 512.

Pattern: [^:*]*

Required: No

filterPattern

A symbolic description of how CloudWatch Logs should interpret the data in each log event. For example, a log event can contain timestamps, IP addresses, strings, and so on. You use the filter pattern to specify what to look for in the log event message.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 1024.

Required: No

logGroupName

The name of the log group.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 512.

Pattern: [\.\-_/#A-Za-z0-9]+

Required: No

metricTransformations

The metric transformations.

Type: Array of MetricTransformation objects

Array Members: Fixed number of 1 item.

Required: No
