TheOmenDen Shared Logging

This library contains a basic logging implementation and some simple extensions that can be used in addition to your normal logging providers.

• 1st note: this library depends on The Omen Den Shared Library.

• 2nd note, this library is not affiliated with the fine folks at Serilog, however it does define an enricher and extensions for Serilog consumers. Credit to Serilog

• 3rd note, this library makes use of MurmurHash which can be found here: MurmurHash

We hope to accomplish the following things within the library, and will continue to provide maintenance and a plan for future improvements.

1. Templates

• Errors - Custom constant string error message templates.
  • Allows for custom error messages to be displayed and logged out more efficiently.
• EventIds - Our custom extensions on Microsoft.Extensions.Logging.EventId struct.
  • Allows for more accurate tracing of events and where they occurred in an application.
• Logging - Provides basic constant string logging messaging templates.
  • This enables you to list Request Pathing, and Logging context Pathing with these templates.
• StartUp - Provides basic constant string templates for bootstrapping an application.

2. Extensions

• LoggerExtensions
  • Provides extensions on the Microsoft.Extensions.Logging.ILogger interface
    • TraceMessageProfiling
      • Allows for the logging of milliseconds an operation within the application took to finish.
    • TraceMessageValidationFailed
      • Allows for the logging of validation failures.
    • TraceBeforeValidatingMessage
      • Allows for the logging before a validation event takes place.
    • TraceMessageModelBinderUsed
      • Allows the logging of a Model binder operation that was used in the process of validation.
    • TraceMessageValidationPassed
      • Logs out a successful message when a validation event is successful.

3. Serilog

• EventTypeEnricher
  • A naive implementation for enriching a logging context with a hashed Id.
• RequestLoggingConfigurer
  • EnrichFromRequest
    • Allows for the Serilog.IDiagnosticContext to log out properties from a provided Microsoft.AspNetCire.Http.HttpContext
• EnvironmentLoggerConfigurationExtensions
  • Allows for registering the EventTypeEnricher using the Enrich().WithEventType() syntax in your Serilog logger configuration.

4. Http Message Logging

• MetaData
  • A simple structure meant to provide basic metadata information for Http Request and Responses.
  • Provides a way to see the information logged in a more structured form.
• DelegatingLogHandler
  • A DelegatingHandler implementation that allows for logging of specific properties in an HttpMessage.
  • Comes with a set of of extensions in HttpMessageHandlerRegistrationExtensions.cs to allow you to register the handler itself as a Transient service, then onto HttpClients.
    • Can also be configured to register on ALL clients defined in the same service collection.

5. Options

• ApiExceptionOptions and OptionsDelegates
  • A simple container for actions that allow for log level adjustments and exception detail customizations
  • These can be configured within middleware in your .NET applications.
    • AddResponseDetails
      • Allows one to define how specific exceptions are logged out to a Payload's message.
      • Meant to be used in conjunction with OptionsDelegates.UpdateApiErrorResponse
    • DetermineLogLevel
      • A way to determine how certain exceptions are reported in the logs
      • Meant to be combined with OptionsDelegates.DetermineLogLevel - which allows for certain exceptions to be reported with a LogLevel.Critical instead of LogLevel.Error
