Basic Metrics
The following are the default metrics for the API Gateway namespace.
The metrics whose names are displayed in bold below are the key metrics selected from the default metrics provided by API Gateway. Key metrics are used to configure service dashboards that are automatically built for each service in ServiceWatch.
Each metric guides users via the user guide on which statistical value is meaningful when querying that metric, and among the meaningful statistics, the values displayed in bold are the primary statistics. In the service dashboard, you can view key metrics using primary statistical values.
