title: .net core log filtering on certain requests
body: <p>In our production environment we have a .net core web service which is load balanced and as a result the load balancer calls a special /health URL every second to check that the service is still up. When the loglevel is set to Info, the log file is quickly filled due to these repeated calls. Seeing as the logs in question come from the .net core framework I can't see how I could filter out these requests without filtering out all requests. Example of the log for this type of request is:</p>
  
  <pre><code>info: Microsoft.AspNetCore.Hosting.Internal.WebHost[1]
        Request starting HTTP/1.1 GET http://localhost:5555/Health
  info: Microsoft.AspNetCore.Hosting.Internal.WebHost[2]
        Request finished in 1674.6082ms 200
  </code></pre>
  
  <p>Any idea how we could filter these out without also filtering out all other requests ?</p>
