Python OpenTelemetry 事件在 Application Insights中的使用

Question

我正在按照下面的指南，尝试为我的Django应用程序设置Azure Application Insights的日志记录：

https://uptrace.dev/get/instrument/opentelemetry-django.html https://uptrace.dev/opentelemetry/python-tracing.html https://opentelemetry.io/docs/languages/python/automatic/logs-example/

最后我写出了这样的代码：

myapp/manage.py

def main():
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myapp.settings')

    # Configure OpenTelemetry to use Azure Monitor with the specified connection string
    configure_azure_monitor(
        connection_string="InstrumentationKey=myKey;IngestionEndpoint=https://centralus-2.in.applicationinsights.azure.com/;LiveEndpoint=https://centralus.livediagnostics.monitor.azure.com/",
    )

    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc

    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()

myapp/views.py

import logging
from opentelemetry import trace

class SomeView(LoginRequiredMixin, TemplateView):
    login_required = True
    template_name = "myapp/index.html"

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)

        tracer = trace.get_tracer(__name__)

        with tracer.start_as_current_span("SomeView") as span:
            if span.is_recording():
                span.set_attribute("user.id", self.request.user.id)
                span.set_attribute("user.email", self.request.user.email)

                span.add_event("log", {
                    "log.severity": "info",
                    "log.message": "Mark was here.",
                    "user.id": self.request.user.id,
                    "user.email": self.request.user.email,
                })

                span.add_event("This is a span event")
                logging.getLogger().error("This is a log message")

        context['something'] = SomeThing.objects.all()
        
        return context

好的地方是：我确实在Application Insights中看到了结果。

当我查看端到端的事务详情时，我看到了一些像这样的内容，这非常棒。

1:32:53.587 PM  Trace   Severity level: Information, Message: message
1:32:53.602 PM  Trace   Severity level: Information, Message: here

不过，我遇到的问题是，无法记录实际的事件。所以当我在Application Insights中点击菜单里的“活动日志”时，只看到一条消息：“没有事件可显示”。

所以，我的追踪功能是正常的，但我无法记录“事件”。任何帮助都将非常感激。

Answer 1

据我所知，这个问题是使用OpenTelemetry创建事件时出现的一个bug。我在Github上提出了支持请求。

作为替代方案，你可以把下面的代码整合到你的Django项目中的views.py和manage.py文件里：

import logging
from opencensus.ext.azure.log_exporter import AzureEventHandler


rithwik_lor = logging.getLogger(__name__)
rithwik_lor.addHandler(AzureEventHandler(connection_string='InstrumentationKey=hg65f87-u8frx;IngestionEndpoint=https://eastus-8.in.applicationinsights.azure.com/;LiveEndpoint=https://eastus.livediagnostics.monitor.azure.com/'))
rithwik_lor.setLevel(logging.INFO)
rithwik_lor.info('Hi Mr.Bojja, Event Created In Events')

输出：
