使用 AWS Health 與其他系統整合 AWS Health API
AWS Health 是一項 RESTful Web 服務,可HTTPS用作傳輸和JSON訊息序列化格式。您的應用程式程式碼可以直接向 AWS Health 提出請求API。當您RESTAPI直接使用 時,您必須撰寫必要的程式碼來簽署和驗證您的請求。如需 AWS Health 操作和參數的詳細資訊,請參閱AWS Health API參考 。
注意
您必須擁有來自 的業務、企業功能提升或企業支援計劃,AWS SupportSubscriptionRequiredException
錯誤。
您可以使用 AWS SDKs來包裝 AWS Health RESTAPI呼叫,進而簡化應用程式開發。您可以指定您的 AWS 憑證,這些程式庫會為您處理身分驗證和請求簽署。
AWS Health 也在 中提供 AWS Health 儀表板 AWS Management Console ,供您用來檢視和搜尋事件和受影響的實體。請參閱 AWS Health 儀表板入門。
選擇請求的 AWS Health API端點
AWS Health API 遵循多區域應用程式架構,並在主動被動組態中有兩個區域端點。若要支援主動被動DNS容錯移轉, AWS Health 提供單一的全域端點。您可以在全域端點上執行DNS查詢,以判斷作用中端點和對應的簽署 AWS 區域。這可協助您了解要在程式碼中使用的端點,以便從 取得最新資訊 AWS Health。
當您向全域端點提出請求時,您必須將 AWS 存取憑證指定至您鎖定的區域端點,並為區域設定簽署。否則,您的身分驗證可能會失敗。如需詳細資訊,請參閱簽署 AWS Health API請求。
下表代表預設組態。
描述 | 簽署區域 | 端點 | 通訊協定 |
---|---|---|---|
作用中 |
us-east-1 |
health.us-east-1.amazonaws.com |
HTTPS |
被動 |
us-east-2 |
health.us-east-2.amazonaws.com |
HTTPS |
全球服務 |
us-east-1 注意這是目前作用中端點的簽署區域。 |
global.health.amazonaws.com |
HTTPS |
若要判斷端點是否為作用中端點 ,請DNS查詢全域端點 CNAME,然後從解析的名稱中擷取 AWS 區域。
範例 :DNS查詢全域端點
下列命令會在 global.health.amazonaws.com 端點上完成DNS查詢。命令接著會傳回 us-east-1 區域端點。此輸出會告訴您應該將哪個端點用於 AWS Health。
dig global.health.amazonaws.com | grep CNAME
global.health.amazonaws.com. 10 IN CNAME health.us-east-1.amazonaws.com
提示
主動和被動端點都會傳回 AWS Health 資料。不過,最新的 AWS Health 資料只能從作用中端點取得。來自被動端點的資料最終將與主動端點一致。建議您在作用中端點變更時重新啟動任何工作流程。
嘗試 AWS Health 端點示範
在下列程式碼範例中, AWS Health 會使用針對全域端點的DNS查詢來判斷作用中區域端點和簽署區域。然後,如果作用中端點變更,程式碼會重新啟動工作流程。

範例 : AWS Health 事件輸出

Examples of ephemeral workloads include changes to Amazon Elastic Compute Cloud (Amazon EC2) Spot Instances, Amazon Elastic MapReduce jobs, and Amazon EC2 Autoscaling. This update will optimize CI models for EC2 Instance, SecurityGroup, Network Interface, Subnet, VPC, VPN Gateway, and Customer Gateway resource types to record direct relationships and deprecate indirect relationships. A direct relationship is defined as a one-way relationship (A->B) between a resource (A) and another resource (B), and is typically derived from the Describe API response of resource (A). An indirect relationship, on the other hand, is a relationship that AWS Config infers (B->A), in order to create a bidirectional relationship. For example, EC2 instance -> Security Group is a direct relationship, since security groups are returned as part of the describe API response for an EC2 instance. But Security Group -> EC2 instance is an indirect relationship, since EC2 instances are not returned when describing an EC2 Security group. Until now, AWS Config has recorded both direct and indirect relationships. With the launch of Advanced queries in March 2019, indirect relationships can easily be answered by running Structured Query Language (SQL) queries such as: SELECT resourceId, resourceType WHERE resourceType ='AWS::EC2::Instance' AND relationships.resourceId = 'sg-234213' By deprecating indirect relationships, we can optimize the information contained within a Configuration Item while reducing AWS Config costs related to relationship changes. This is especially useful in case of ephemeral workloads where there is a high volume of configuration changes for EC2 resource types. Which resource relationships are being removed? Resource Type: Related Resource Type 1 AWS::EC2::CustomerGateway: AWS::VPN::Connection 2 AWS::EC2::Instance: AWS::EC2::EIP, AWS::EC2::RouteTable 3 AWS::EC2::NetworkInterface: AWS::EC2::EIP, AWS::EC2::RouteTable 4 AWS::EC2::SecurityGroup: AWS::EC2::Instance, AWS::EC2::NetworkInterface 5 AWS::EC2::Subnet: AWS::EC2::Instance, AWS::EC2::NetworkACL, AWS::EC2::NetworkInterface, AWS::EC2::RouteTable 6 AWS::EC2::VPC: AWS::EC2::Instance, AWS::EC2::InternetGateway, AWS::EC2::NetworkACL, AWS::EC2::NetworkInterface, AWS::EC2::RouteTable, AWS::EC2::Subnet, AWS::EC2::VPNGateway, AWS::EC2::SecurityGroup 7 AWS::EC2::VPNGateway: AWS::EC2::RouteTable, AWS::EC2::VPNConnection Alternate mechanism to retrieve this relationship information: The SelectResourceConfig API accepts a SQL SELECT command, performs the corresponding search, and returns resource configurations matching the properties. You can use this API to retrieve the same relationship information. For example, to retrieve the list of all EC2 Instances related to a particular VPC vpc-1234abc, you can use the following query: SELECT resourceId, resourceType WHERE resourceType ='AWS::EC2::Instance' AND relationships.resourceId = 'vpc-1234abc' If you have any questions regarding this deprecation plan, please contact AWS Support [1]. Additional sample queries to retrieve the relationship information for the resources listed above is provided in [2].

In order to avoid an interruption in service, we encourage you to act now, by ensuring that you connect to AWS FIPS endpoints at a TLS version of 1.2. If your client applications fail to support TLS 1.2 it will result in connection failures when TLS versions below 1.2 are no longer supported.\n\nBetween now and March 31, 2021 AWS will remove TLS 1.0 and TLS 1.1 support from each FIPS endpoint where no connections below TLS 1.2 are detected over a 30-day period. After March 31, 2021 we may deploy this change to all AWS FIPS endpoints, even if there continue to be customer connections detected at TLS versions below 1.2. \n\nWe will provide additional updates and reminders on the AWS Security Blog, with a ‘TLS’ tag [1]. If you need further guidance or assistance, please contact AWS Support [2] or your Technical Account Manager (TAM). Additional information is below.\n\nHow can I identify clients that are connecting with TLS 1.0/1.1?\nFor customers using S3 [3], Cloudfront [4] or Application Load Balancer [5] you can use your access logs to view the TLS connection information for these services, and identify client connections that are not at TLS 1.2. If you are using the AWS Developer Tools on your clients, you can find information on how to properly configure your client’s TLS versions by visiting Tools to Build on AWS [7] or our associated AWS Security Blog has a link for each unique code language [7].\n\nWhat is Transport Layer Security (TLS)?\nTransport Layer Security (TLS Protocols) are cryptographic protocols designed to provide secure communication across a computer network [6].\n\nWhat are AWS FIPS endpoints? \nAll AWS services offer Transport Layer Security (TLS) 1.2 encrypted endpoints that can be used for all API calls.
