SkyWalking 查询指标两种方法
GraphQL API
PromQL API


https://skywalking.apache.org/docs/main/v9.4.0/en/api/query-protocol/
https://github.com/apache/skywalking-query-protocol

与 RESTful 不同，每一个的 GraphQL 服务对外只提供一个 endpoint

http://{SKYWALKING_oap}:{port}/graphql
http://192.168.1.10:12800/graphql

grpc端口 agent数据报送 11800
http端口 12800  ，给ui 提供 graphql接口
ui端口 8080
LogQL API 端口 3100
PromQL API 端口  9090

query {
   getTimeInfo {
    timezone
    currentTimestamp
  }
}

query 可省略
{
   getTimeInfo {
    timezone
    currentTimestamp
  }
}

使用json格式
{
  "query":"{查询语句}"
  "variables":"{参数和参数值}"
}


{
  "query":"{getTimeInfo {timezone currentTimestamp}}"
}



query ReadMetricsValues {
    readMetricsValues(condition: {
    name: "service_cpm", entity: {scope: Service, serviceName: "demoapp", normal: true}
  }, duration: {
    start: "2024-03-25 00",
    end: "2024-03-26 13",
    step: HOUR
  }) {
        label
        values {
            values {
                id
                value
            }
        }
    }
}



查询service
{
  "query": "query queryServices($duration: Duration!,$keyword: String!) {    services: getAllServices(duration: $duration, group: $keyword) {      key: id      label: name      group    }  }",
  "variables": {
    "duration": {
        "start": "2024-03-26 00",
        "end": "2024-03-26 15",
        "step": "HOUR"},
    "keyword": ""
  }
}

返回结果
