yaml：使用 go 时出现取消警告错误

Question

我运行代码：https://github.com/prometheus-community/json_exporter 通过更改配置将json数据转换为普罗米修斯指标数据类型

错误是：

level=error ts=2021-07-05T06:19:52.714Z caller=main.go:58 msg="Error loading config" err="yaml: unmarshal errors:\n  line 7: cannot unmarshal !!str `id:\"{.id}\"` into map[string]string"

这是我的yaml配置：

metrics:

- name: running_applications

  type: object 

  help: Information on running applications

  path: '{.apps.app[?(@.state=="RUNNING")]}'

  labels:

        id:'{.id}'

  values:

        memory: '{.allocatedMB}'

        vcores: '{.allocatedVCores}'

以下是 json 的一部分：

{"apps":

{"app":

[{"id":"application_1622098898935_1480","user":"hive","name":"HIVE-b5770b0d-fdd0-4ee4-86f8-1684df70dae9","queue":"default","state":"FINISHED","finalStatus":"SUCCEEDED","progress":100.0,"trackingUI":"History","trackingUrl":"http://tst02.bj2.sdbmcc.com:30999/proxy/application_1622098898935_1480/","diagnostics":"Attempt recovered after RM restartSession timed out, lastDAGCompletionTime=1624665783612 ms, sessionTimeoutInterval=600000 ms\nSession stats:submittedDAGs=1, successfulDAGs=1, failedDAGs=0, killedDAGs=0\n","clusterId":1625045401338,"applicationType":"TEZ","applicationTags":"hive_20210626080103_7098ab3b-ea51-4780-ba5d-aa823335b102,userid=user-app_ebupt","priority":0,"startedTime":1624665666232,"finishedTime":1624666419590,"elapsedTime":753358,"amContainerLogs":"http://tst02.bj2.sdbmcc.com:8042/node/containerlogs/container_e82_1622098898935_1480_01_000001/hive","amHostHttpAddress":"tst02.bj2.sdbmcc.com:8042","masterNodeId":"tst02.bj2.sdbmcc.com:45454","allocatedMB":-1,"allocatedVCores":-1,"reservedMB":-1,"reservedVCores":-1,"runningContainers":-1,"memorySeconds":3752447,"vcoreSeconds

}

}

根据马可的建议，修改 yaml 配置文件如下：metrics:- name: running_applications  type: object   help: Information on running applications  path: '{.apps.app[?(@.state=="RUNNING")]}'  labels:        id: '{.id}'  values:        memory: '{.allocatedMB}'        vcores: '{.allocatedVCores}'
