| Rate of Data Processed | The rate of data processed per second between the poll interval（in MB/s）. |
| Data Processed | The total amount of data processed between the poll interval（in MB）. |
| OVERALL LATENCY | |
| Overall Latency | The average time between when API Gateway receives a request from a client and when it returns a response to the client, between the poll interval（in ms）. The latency includes the integration latency and other API Gateway overhead. |
| INTEGRATION LATENCY | |
| Integration Latency | The average time between when API Gateway relays a request to the backend and when it receives a response from the backend, between the poll interval（in ms）. |
| CLIENT ERRORS | |
| 4xx Errors | The total number of client-side errors captured between the poll interval. |
| SERVER ERRORS | |
| 5xx Errors | The total number of server-side errors captured between the poll interval. |
| API ERROR RATE | |
| 4xx Error Rate | The percentage of total API requests that resulted in client-side errors（4xx status codes）between the poll interval（in %）. |
| 5xx Error Rate | The percentage of total API requests that resulted in server-side errors（5xx status codes）between the poll interval（in %）. |
構成（HTTP API）
| パラメーター | 説明 |
|---|---|
| CONFIGURATION | |
| HTTP API Name | Name of the HTTP API resource. |
| API Endpoint | The URI of the HTTP API. |
| Execute API Endpoint | Specifies whether clients can invoke your API by using the default execute-api endpoint. Possible values: Enabled/Disabled. |
| API Key Selection Expression | This expression is evaluated when the service determines the given request should proceed only if the client provides a valid API key. Possible values: $request.header.x-api-key/$context.authorizer.usageIdentifierKey. |
| Route Selection Expression | The route selection expression for the API. |
| Creation Time | The timestamp when the HTTP API resource was created. |
