UserAgent/作業系統的 Google App Engine 流量分析

我有一個在 Google App Engine 中執行的應用程序。他們的生態系統似乎為 StackDriver 中的日誌分析提供了一些工具。

對於我的生活，我無法弄清楚如何獲得按使用者代理或作業系統分解的 HTTP 請求的簡單圖表。

如何配置這樣的圖表？

截至目前，這是不可能的，如文件“指標種類”部分下的表格中所述，其中表示您無法創建值類型為 STRING 的自定義指標。

我已經通過在相應的 repo 文件中使用函式 create_metric_descriptor並編輯其正文來確認這一點：

descriptor.value_type = (monitoring_v3.enums.MetricDescriptor.ValueType.STRING)  

並得到這個錯誤：

InvalidArgument: 400 Field metricDescriptor.valueType had an invalid value of "STRING": When creating metric custom.googleapis.com/my_metric_6365: the value type is not supported for custom metrics.

無論如何，您仍然可以從 Stackdriver Logging 獲取有價值的資訊，以將其傳輸到您選擇的任何數據科學和視覺化方法。您將盡可能從 protoPayload.userAgent 欄位中提取有關作業系統的資訊。

只需試用 Cloud SDK，例如，如下所示：

$ project_id= #FILL
$ module_id=default #EDIT
$ version_id= #FILL
$ gcloud logging read "resource.type=gae_app AND resource.labels.module_id=$module_id AND resource.labels.version_id=$version_id AND logName=(projects/$project_id/logs/stderr OR projects/$project_id/logs/appengine.googleapis.com%2Frequest_log)" --format "json(receiveTimestamp, protoPayload.userAgent, protoPayload.ip, protoPayload.resource)"

你會得到如下條目：

           "protoPayload": {
                   "ip": "....",
                   "resource": "/",
