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.
Contents
- 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

The name of the log group.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 512.
