UserAgent/操作系统的 Google App Engine 流量分析

  • 772

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为 StackDriver 中的日志分析提供了一些工具。

对于我的生活，我无法弄清楚如何获得按用户代理或操作系统分解的 HTTP 请求的简单图表。

如何配置这样的图表？

    截至目前，这是不可能的，如文档“指标种类”部分下的表格中所述，其中表示您无法创建值类型为 STRING 的自定义指标。

    我已经通过在相应的 repo 文件中使用函数 create_metric_descriptor并编辑其正文来确认这一点：

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

    并得到这个错误：

    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，以将其传输到您选择的任何数据科学和可视化方法。您将尽可能从 protoPayload.userAgent 字段中提取有关操作系统的信息。

    只需试用 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)"

    你会得到如下条目：

            "protoPayload": {
                    "ip": "....",
