/AWS1/CL_CWLMETRICTRANSFMTION¶
Indicates how to transform ingested log events to metric data in a CloudWatch metric.
CONSTRUCTOR¶
IMPORTING¶
Required arguments:¶
iv_metricname TYPE /AWS1/CWLMETRICNAME /AWS1/CWLMETRICNAME¶
The name of the CloudWatch metric.
iv_metricnamespace TYPE /AWS1/CWLMETRICNAMESPACE /AWS1/CWLMETRICNAMESPACE¶
A custom namespace to contain your metric in CloudWatch. Use namespaces to group together metrics that are similar. For more information, see Namespaces.
iv_metricvalue TYPE /AWS1/CWLMETRICVALUE /AWS1/CWLMETRICVALUE¶
The value to publish to the CloudWatch metric when a filter pattern matches a log event.
Optional arguments:¶
iv_defaultvalue TYPE /AWS1/RT_DOUBLE_AS_STRING /AWS1/RT_DOUBLE_AS_STRING¶
(Optional) The value to emit when a filter pattern does not match a log event. This value can be null.
it_dimensions TYPE /AWS1/CL_CWLDIMENSIONS_W=>TT_DIMENSIONS TT_DIMENSIONS¶
The fields to use as dimensions for the metric. One metric filter can include as many as three dimensions.
Metrics extracted from log events are charged as custom metrics. To prevent unexpected high charges, do not specify high-cardinality fields such as
IPAddressorrequestIDas dimensions. Each different value found for a dimension is treated as a separate metric and accrues charges as a separate custom metric.CloudWatch Logs disables a metric filter if it generates 1000 different name/value pairs for your specified dimensions within a certain amount of time. This helps to prevent accidental high charges.
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 Amazon Web Services Charges.
iv_unit TYPE /AWS1/CWLSTANDARDUNIT /AWS1/CWLSTANDARDUNIT¶
The unit to assign to the metric. If you omit this, the unit is set as
None.
