如何使用 StackDriver API 的 v2 查询 BigQuery 用法？

Question

我计划使用 StackDriver API 跟踪 BigQuery 的使用情况，并且有一个很好的设置教程 here. However, the queries here use the deprecated v1 of the API and the available documentation 也仍然适用于 v1。

在 BigQuery 控制台中，v2 仅提供以下字段：

logName
timestamp
severity
insertId
resource
resource.type
resource.labels
resource.labels.project_id
httpRequest
httpRequest.requestMethod
httpRequest.requestUrl
httpRequest.requestSize
httpRequest.status
httpRequest.responseSize
httpRequest.userAgent
httpRequest.remoteIp
httpRequest.serverIp
httpRequest.referer
httpRequest.cacheHit
httpRequest.cacheValidatedWithOriginServer
httpRequest.latency
httpRequest.cacheLookup
httpRequest.cacheFillBytes
operation
operation.id
operation.producer
operation.first
operation.last
protopayload_google_cloud_audit_auditlog
protopayload_google_cloud_audit_auditlog.serviceName
protopayload_google_cloud_audit_auditlog.methodName
protopayload_google_cloud_audit_auditlog.resourceName
protopayload_google_cloud_audit_auditlog.numResponseItems
protopayload_google_cloud_audit_auditlog.status
protopayload_google_cloud_audit_auditlog.status.code
protopayload_google_cloud_audit_auditlog.status.message
trace
sourceLocation  
sourceLocation.file 
sourceLocation.line 
sourceLocation.function

现在没有 totalBilledBytes 字段，该字段在示例 v1 查询中用于计算使用情况。 API?

的v2如何查询使用费

Answer 1

有一个很好的tutorial查询审计日志来获取这些信息。下面是一个示例查询（假设您已经将审核日志数据导出回 BigQuery）。

SELECT
  query_date,
  ROUND(((total_bytes*5)/1000000000000),2) Cost_In_Dollars
FROM (
  SELECT
    STRFTIME_UTC_USEC(metadata.timestamp,"%Y-%m-%d") AS query_date,
    SUM(protoPayload.serviceData.jobCompletedEvent.job.jobStatistics.totalBilledBytes) AS total_bytes
  FROM
    TABLE_DATE_RANGE(AuditLogs.cloudaudit_googleapis_com_data_access_, DATE_ADD(CURRENT_TIMESTAMP(), -7, 'DAY'), CURRENT_TIMESTAMP())
  WHERE
    protoPayload.serviceData.jobCompletedEvent.eventName = 'query_job_completed'
  GROUP BY
    query_date )
