## 健康檢查 健康檢查[架構概述](../Introduction/Architectureoverview/Healthchecking.md)。如果為集群配置了健康檢查，則會發出相應的統計信息。詳見請參考[統計](../Configurationreference/Clustermanager/Statistics.md)相關文檔。 - [HealthCheck](#healthcheck) - [HealthCheck.Payload](#healthcheckpayload) - [HealthCheck.HttpHealthCheck](#healthcheckhttphealthcheck) - [HealthCheck.TcpHealthCheck](#healthchecktcphealthcheck) - [HealthCheck.RedisHealthCheck](#healthcheckredishealthcheck) ### HealthCheck [HealthCheck proto](https://github.com/envoyproxy/data-plane-api/blob/master/api/health_check.proto#L14) ``` { "timeout": "{...}", "interval": "{...}", "interval_jitter": "{...}", "unhealthy_threshold": "{...}", "healthy_threshold": "{...}", "reuse_connection": "{...}", "http_health_check": "{...}", "tcp_health_check": "{...}", "redis_health_check": "{...}" } ``` - **timeout**<br /> ([Duration](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#duration)) 等待健康檢查響應的時間。如果達到超時，則嘗試健康檢查將被視為失敗。 - **interval**<br /> ([Duration](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#duration)) 每次嘗試健康檢查之間的時間間隔。 - **interval_jitter**<br /> ([Duration](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#duration)) 可選，抖動量（以毫秒為單位）。如果指定，在Envoy內部將抖動量疊加到時間間隔上。 - **unhealthy_threshold**<br /> ([UInt32Value](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#uint32value)) 在主機被標記為不健康之前，需要進行不健康的健康檢查次數。請注意，對于http運行健康檢查，如果主機以503響應，此閾值將被忽略，并且主機立即被視為不健康。 - **healthy_threshold**<br /> ([UInt32Value](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#uint32value)) 主機在標記為健康之前所需的健康檢查次數。請注意，在啟動過程中，只需要一次成功的健康檢查即可將主機標記為健康狀態。 - **reuse_connection**<br /> ([BoolValue](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#boolvalue)) 健康檢查之間復用健康檢查連接。默認是`true`。 - **http_health_check**<br /> ([HealthCheck.HttpHealthCheck](#healthcheckhttphealthcheck)) HTTP健康檢查。 - **tcp_health_check**<br /> ([HealthCheck.TcpHealthCheck](#healthchecktcphealthcheck)) TCP健康檢查 - **redis_health_check**<br /> ([HealthCheck.RedisHealthCheck](#healthcheckredishealthcheck)) Redis健康檢查 **注意：只能在`http_health_check`，`tcp_health_check`，`redis_health_check`選其中一個進行設置。** ### HealthCheck.Payload [HealthCheck.Payload proto](https://github.com/envoyproxy/data-plane-api/blob/master/api/health_check.proto#L43) 描述載荷中有效載荷的字節編碼。 ``` { "text": "..." } ``` - **text**<br /> ([string](https://developers.google.com/protocol-buffers/docs/proto#scalar), REQUIRED) 十六進制編碼載荷，例如，“000000FF”。準確地說，必須設置一個文本。 ### HealthCheck.HttpHealthCheck [HealthCheck.HttpHealthCheck proto](https://github.com/envoyproxy/data-plane-api/blob/master/api/health_check.proto#L55) ``` { "path": "...", "service_name": "..." } ``` - **path**<br /> ([string](https://developers.google.com/protocol-buffers/docs/proto#scalar), REQUIRED) 指定運行健康檢查期間，所請求的HTTP路徑。例如`/healthcheck`。 - **service_name**<br /> ([string](https://developers.google.com/protocol-buffers/docs/proto#scalar)) 可選，服務名稱參數，用于驗證運行狀況檢查的群集的身份。請參閱[架構概述](../Introduction/Architectureoverview/Healthchecking.md)以獲取更多信息。 ### HealthCheck.TcpHealthCheck [HealthCheck.TcpHealthCheck proto](https://github.com/envoyproxy/data-plane-api/blob/master/api/health_check.proto#L77) ``` { "send": "{...}", "receive": [] } ``` - **send**<br /> ([HealthCheck.Payload](#healthcheckpayload)) 若有效載荷為空，意味著僅做連接的健康檢查。 - **receive**<br /> ([HealthCheck.Payload](#healthcheckpayload)) 當檢查響應時，執行模糊匹配，每個二進制塊必須被找到，并且按照指定的順序，但不一定是連續的。 ### HealthCheck.RedisHealthCheck [HealthCheck.RedisHealthCheck proto](https://github.com/envoyproxy/data-plane-api/blob/master/api/health_check.proto#L87) ``` {} ``` ## 返回 - [上一級](../v2APIreference.md) - [首頁目錄](../README.md)
