Valid values: - HTTP (default): Check whether the server application is healthy by sending HEAD or GET requests to simulate browser access requests. - HTTPS: Check whether the server application is healthy by sending HEAD or GET requests to simulate browser access requests. (Data encryption, more secure compared with HTTP.) - TCP: Detect whether the server port is alive by sending SYN handshake messages. - GRPC: Check whether the server application is healthy by sending a POST or GET request. - GRPCS: Check whether the server application is healthy by sending a POST or GET request. |
| HealthCheckTemplateName | No | String | Health check template name. It must be 1-255 characters long and can contain digits, upper- and lower-case letters, Chinese characters, half-width periods (.), underscores (_), and dashes (-). |
| HealthCheckTimeout | No | Integer | timeout period for the health check. Unit: seconds. Valid values: 2-60. Default value: 2. |
| HealthCheckUnhealthyThreshold | No | Integer | Threshold for determining an unhealthy backend service. The backend service status changes from healthy to unhealthy after the health check fails consecutively for this number of times. Value range: 2-10. Default value: 2. |
| Tags.N | No | Array of TagInfo | Tag. |
| Parameter Name | Type | Description |
