英文:
Creating event in eventbridge when an RDS instance is started
问题
我正在尝试学习并尝试使用AWS服务。我想在EventBridge中创建一个规则，当启动RDS数据库实例时，会简单地触发一个Lambda函数。这是我使用的规则：{"version": "0","detail-type": "RDS DB Instance Event","source": "aws.rds","region": "eu-south-2","resources": ["XXX"],"detail": {"EventCategories": ["notification"],"SourceType": "DB_INSTANCE","SourceArn": "XXX","Message": "DB instance started.","EventID": "RDS-EVENT-0088"}}我收到一个错误消息：“事件模式无效。原因：“version”必须是对象或数组...”我猜这是一个格式错误，但实在想不出...我只是传递一个字符串。当我尝试从[官方文档](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/rds-cloud-watch-events.html)中测试模式时，我收到相同的错误。这可能是一些非常愚蠢的事情，但我将非常感激您的帮助。

I am trying to learn and play a bit with aws serevices. I want to create a rule in the eventbridge that would simply lanch a lambda function when an rds database instance is started.
Here is the rule I use:
{"version": "0","detail-type": "RDS DB Instance Event","source": "aws.rds","region": "eu-south-2","resources": ["XXX"],"detail": {"EventCategories": ["notification"],"SourceType": "DB_INSTANCE","SourceArn": "XXX","Message": "DB instance started.","EventID": "RDS-EVENT-0088"}}
I get an error "Event pattern is not valid. Reason: "version" must be an object or an array at... "
I guess it is a formating error, but literally can't figure it out... I'm just passing a string. When I try to test the pattern from the official documentation I get the same error.
It is probably something very stupid, but I would greatly appreciate your help.

您的规则是错误的。
这不是规则，而是一个将被规则匹配的事件示例。
您可以通过以下方式创建规则：
-
转到事件桥，创建规则
-
选择事件源为AWS
-
选择示例事件类型为"输入自定义事件"，并输入下面提到的事件（这是根据问题标题生成的事件，用于启动实例时生成的事件）。要查看其他事件ID，请参考文档
-
0088事件ID是RDS实例启动时生成的事件
{"version": "0","id": "68f6e973-1a0c-d37b-f2f2-94a7f62ffd4e","detail-type": "RDS DB Instance Event","source": "aws.rds","account": "123456789012","time": "2018-09-27T22:36:43Z","region": "us-east-1","resources": ["arn:aws:rds:us-east-1:123456789012:db:mysql-instance-2018-10-06-12-24"],"detail": {"EventCategories": ["failover"],"SourceType": "DB_INSTANCE","SourceArn": "arn:aws:rds:us-east-1:123456789012:db:mysql-instance-2018-10-06-12-24e","Date": "2018-09-27T22:36:43.292Z","SourceIdentifier": "rds:mysql-instance-2018-10-06-12-24","Message": "一个多AZ故障转移已经完成。", // 消息可能会有所不同"EventID": "RDS-EVENT-0088"}}
- 创建一个自定义模式并使用以下JSON。
{"source": ["aws.rds"],"detail-type": ["RDS DB Instance Event"],"detail": {"EventID": ["RDS-EVENT-0088"]}}
如果您测试这个规则，对于上面提到的事件，它将匹配。
如何找到示例事件[如评论所述]
英文:
Your rule is wrong.
This is the not the rule but an example of event which will be matched by rule.
You can actually create a rule by doing the following:-
-
go to eventbridge , create rule
-
select event source as aws
-
choose sample events type as enter my own and enter the below mentioned event ( this is the event which is generated when instance is started as per title of questions). to check other event id, follow docs
-
0088 event id is the event when rds instance is started
{"version": "0","id": "68f6e973-1a0c-d37b-f2f2-94a7f62ffd4e","detail-type": "RDS DB Instance Event","source": "aws.rds","account": "123456789012","time": "2018-09-27T22:36:43Z","region": "us-east-1","resources": ["arn:aws:rds:us-east-1:123456789012:db:mysql-instance-2018-10-06-12-24"],"detail": {"EventCategories": ["failover"],"SourceType": "DB_INSTANCE","SourceArn": "arn:aws:rds:us-east-1:123456789012:db:mysql-instance-2018-10-06-12-24e","Date": "2018-09-27T22:36:43.292Z","SourceIdentifier": "rds:mysql-instance-2018-10-06-12-24","Message": "A Multi-AZ failover has completed.", // Message would be something else"EventID": "RDS-EVENT-0088"}}
-
create a custom pattern and use the following json.
{"source": ["aws.rds"],"detail-type": ["RDS DB Instance Event"],"detail": {"EventID": ["RDS-EVENT-0088"]}}
If you test this rule, for the event above mentioned it will match.
