Application Insights Trace Listener with azure functions

问题

I have a bunch of services which emit System.Diagnostics.Trace.* trace messages and when hosted via webapi, I simply include the Microsoft.ApplicationInsights.TraceListener package and my traces are collected in app insights. However, part of the setup requires a web.config file to tell the trace listener to listen and flush like:

<system.diagnostics>
  <sources>
    <source name="TraceLogging" switchName="Verbose">
      <listeners>
        <add name="appinsights" type="Microsoft.ApplicationInsights.TraceListener.ApplicationInsightsTraceListener, Microsoft.ApplicationInsights.TraceListener"/>
      </listeners>
    </source>
  </sources>

From this answer it doesn't seem like I can setup this up via web.confg.

Is there any way to enable the trace listener to send traces to my app insights?

回答1:

There are plans to expose configuration and logging providers extensibility that would enable scenarios like this, but this is not currently supported.
