logging - 无法使用基于日志的指标(指标类型 : "Counter")

Question

我正在努力创建一个图表，其中包含基于日志的指标的 Stackdriver 监控。我的指标是默认没有单位的计数器。
日志可用于我的基于日志的指标，但是当我使用我的指标创建图表时，它显示no data is available for the...。
这是我的指标，它确实有效(称为 isOperatorAllowed):

resource.type="container"
resource.labels.namespace_id="default"
jsonPayload.message="CaseForOperator flags"
logName="projects/PROJECT-ID/logs/app"
jsonPayload.caseForOperatorFlags.isOperatorAllowed=true

这是我的图表的 JSON 配置

{
  "dataSets": [
    {
      "timeSeriesFilter": {
        "filter": "metric.type=\"logging.googleapis.com/user/IsOperatorAllowed\" resource.type=\"gke_container\"",
        "perSeriesAligner": "ALIGN_RATE",
        "crossSeriesReducer": "REDUCE_NONE",
        "secondaryCrossSeriesReducer": "REDUCE_NONE",
        "minAlignmentPeriod": "60s",
        "groupByFields": [],
        "unitOverride": "1"
      },
      "targetAxis": "Y1",
      "plotType": "LINE"
    }
  ],
  "options": {
    "mode": "COLOR"
  },
  "constantLines": [],
  "timeshiftDuration": "0s",
  "y1Axis": {
    "label": "y1Axis",
    "scale": "LINEAR"
  }
}

有人知道我做错了什么吗？

Answer 1

经过讨论和帮助，答案是:
基于日志的指标在创建后仅采用日志。因此，如果您的日志早于指标创建时间戳，它们将不会出现在指标计数/分布中

示例:

Metric: `03/06/2020 15:55:33`
log 1: `02/06/2020 12:00:00`
log 2: `07/06/2020 12:00:00`

Metric count result: 1 (it will be the log 2)

这里说的是 documentation :

New log entries might not match your metric's logs query. A logs-based metric gets data from matching log entries that are received after the metric is created. Logging does not backfill the metric from previous log entries.
