PostSharp.Samples.Logging.ElasticStack: MicroserviceExample

This is the server side of the PostSharp.Samples.Logging.ElasticStack example.

There are two interesting artifacts in this project:

• LoggingActionFilter is an ASP.NET Action Filter, i.e. it runs before the control flow is given to your code in the controller classes. This action filter does the "opposite" of the InstrumentOutgoingRequestsAspect server-side aspect, i.e. it creates a new server-side logging activity (aka context) and assigns:

  • the SyntheticParentId property to the value of the Request-Id HTTP header sent by the client, and
  • custom properties based on the parsing of the Correlation-Context HTTP header.

• SampledLoggingActionFilter is another ASP.NET Action Filter which enables logging for a random 10% subset of incoming requests. The default level, for the remaining 90% of requests, is set to Warning in Program.Main.
