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.
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.
The name of the metric filter.
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.
