Synopsis

Properties

DefaultValue	The value to emit if the pattern does not match a particular event.

FilterName	The name of the metric filter.
FilterPattern	Pattern to search for log events.
MetricName	The name of the metric to emit.
MetricNamespace	The namespace of the metric to emit.

Unit	The unit to assign to the metric.

Properties

DefaultValue

The value to emit if the pattern does not match a particular event.

double? DefaultValue { get; }

Property Value

double?

Remarks

Default: No metric emitted.

Dimensions

The fields to use as dimensions for the metric.

IDictionary<string, string>? Dimensions { get; }

Property Value

IDictionary<string, string>

Remarks

One metric filter can include as many as three dimensions.

Default: - No dimensions attached to metrics.

FilterName

The name of the metric filter.

string? FilterName { get; }

Property Value

string

Remarks

Default: - Cloudformation generated name.

FilterPattern

Pattern to search for log events.

IFilterPattern FilterPattern { get; }

Property Value

IFilterPattern

Remarks

ExampleMetadata: fixture=_generated

MetricName

The name of the metric to emit.

string MetricName { get; }

Property Value

string

Remarks

ExampleMetadata: fixture=_generated

MetricNamespace

The namespace of the metric to emit.

string MetricNamespace { get; }

Property Value

string

Remarks

MetricValue

The value to emit for the metric.

string? MetricValue { get; }

Property Value

string

Remarks

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"

Unit

The unit to assign to the metric.

Unit? Unit { get; }

Property Value

Unit?

Remarks

Default: - No unit attached to metrics.
