MetricFilterProps
- class aws_cdk.aws_logs.MetricFilterProps(*, filter_pattern, metric_name, metric_namespace, default_value=None, metric_value=None, log_group)
Bases:
MetricFilterOptions
Properties for a MetricFilter.
- Parameters:
filter_pattern (
IFilterPattern
) – Pattern to search for log events.metric_name (
str
) – The name of the metric to emit.metric_namespace (
str
) – The namespace of the metric to emit.default_value (
Union
[int
,float
,None
]) – The value to emit if the pattern does not match a particular event. Default: No metric emitted.metric_value (
Optional
[str
]) – The value to emit for the metric. Can either be a literal number (typically “1”), or the name of a field in the structure to take the value from the matched event. If you are using a field value, the field value must have been matched using the pattern. If you want to specify a field from a matched JSON structure, use ‘$.fieldName’, and make sure the field is in the pattern (if only as ‘$.fieldName = *’). If you want to specify a field from a matched space-delimited structure, use ‘$fieldName’. Default: “1”log_group (
ILogGroup
) – The log group to create the filter on.
