CfnMetricFilter.DimensionProperty.Jsii$Proxy
- Enclosing class:
CfnMetricFilter
Because dimensions are part of the unique identifier for a metric, whenever a unique dimension name/value pair is extracted from your logs, you are creating a new variation of that metric.
For more information about publishing dimensions with metrics created by metric filters, see Publishing dimensions with metrics from values in JSON or space-delimited log events .
Metrics extracted from log events are charged as custom metrics. To prevent unexpected high charges, do not specify high-cardinality fields such as
IPAddress
orrequestID
as dimensions. Each different value found for a dimension is treated as a separate metric and accrues charges as a separate custom metric.To help prevent accidental high charges, Amazon disables a metric filter if it generates 1000 different name/value pairs for the dimensions that you have specified within a certain amount of time.
You can also set up a billing alarm to alert you if your charges are higher than expected. For more information, see Creating a Billing Alarm to Monitor Your Estimated AWS Charges .
Example:
// The code below shows an example of how to instantiate this type. // The values are placeholders you should change. import software.amazon.awscdk.services.logs.*; DimensionProperty dimensionProperty = DimensionProperty.builder() .key("key") .value("value") .build();

Method Details
-
getKey
The name for the CloudWatch metric dimension that the metric filter creates.Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (:).

getValue
The log event field that will contain the value for this dimension.This dimension will only be published for a metric if the value is found in the log event. For example,
$.eventType
for JSON log events, or$server
for space-delimited log events.- See Also:
