按 UserAgent/操作系统分析 Google App Engine 流量

我有一个在 Google App Engine 中运行的应用程序。他们的生态系统似乎提供了一些用于分析 StackDriver 日志的功能。

我终其一生都无法弄清楚如何获取按用户代理或操作系统细分的 HTTP 请求的简单图表。

我该如何配置这样的图表？

目前这是不可能的，如下表所示“指标种类”文档的部分，其中说您不能创建具有值类型 STRING 的自定义指标。

我已经通过使用 create_metric_descriptor 函数确认了这一点对应的repo文件并编辑其主体内容：

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

并收到此错误：

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.

无论如何，您仍然可以从 Stackdriver Logging 获取有价值的信息，并将其传输到您选择的任何数据科学和可视化方法。您可以尽可能从 protoPayload.userAgent 字段中提取有关操作系统的信息。

只需尝试使用 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)"

您将获得如下条目：
