https://resilience4j.readme.io/docs/micrometer 有一个公开的指标列表。
现在我的问题是我如何在Grafana中创建一个仪表板，以显示断开的断路器数量。
当我检查数据库时，我可以获取此数据
> SELECT * FROM "resilience4j_circuitbreaker_state" WHERE ("app" = 'document-upload' AND "environment" = 'dev' AND "state" = 'closed')
name: resilience4j_circuitbreaker_state
time app environment metric_type name state value
---- --- ----------- ----------- ---- ----- -----
1585421689542000000 document dev gauge sunService closed 1
1585421689548000000 document dev gauge awsS3 closed 1
1585421749532000000 document dev gauge sunService closed 1
1585421749535000000 document dev gauge awsS3 closed 1
1585421809533000000 document dev gauge sunService closed 1
1585421809535000000 document dev gauge awsS3 closed 1
1585421869535000000 document dev gauge sunService closed 1
1585421869537000000 document dev gauge awsS3 closed 1
由此，我应该如何构造一个返回2的查询，因为我们有两种类型的circuitBreaker，一种用于AWSS3，另一种是SunService 我想要的是一个查询，由于两个断路器现在已闭合，该查询将返回2。
我尝试了
之类的查询SELECT sum(value) FROM "resilience4j_circuitbreaker_state" WHERE ("app" = 'document-upload' AND "environment" = 'dev' AND "state" = 'closed')
但是没有运气
