Common.Logging .NET

Project Build Status

*Note: Build may periodically fail due to issues with the code-coverage tooling (NCover) being unable to reliably connect to the test-runner during test-runs on the CI server platform we've selected (Appveyor). Work continues to investigate this further, but until resolved properly visitors are advised to discount failing builds reported here.

Introduction

Provides a simple logging abstraction to switch between different logging implementations. There is current support for log4net, NLog, Microsoft Enterprise Library logging, Microsoft Application Insights, Microsoft Event Tracing for Windows, and Serilog.

Additionally Common.Logging comes with a set of base classes making the integration of any log system a breeze.

Console Quickstart

This demonstrates how to configure your app to log using the built in Common.Logging console adapter.

1) Install Common.Logging via NuGet

Either open the Package Management Console and enter the following or use the built-in GUI

NuGet: PM> Install-Package Common.Logging

2) Register and configure Common.Logging

Then add the relevant sections to your app.config or web.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <configSections>
    <sectionGroup name="common">
      <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
    </sectionGroup>
  </configSections>

  <common>
    <logging>
      <factoryAdapter type="Common.Logging.Simple.ConsoleOutLoggerFactoryAdapter, Common.Logging">
        <arg key="level" value="INFO" />
        <arg key="showLogName" value="true" />
        <arg key="showDateTime" value="true" />
        <arg key="dateTimeFormat" value="yyyy/MM/dd HH:mm:ss:fff" />
      </factoryAdapter>
    </logging>
  </common>

</configuration>

NLog Quickstart

There are different packages for each major NLog version. Install the correct package for your referenced NLog version. This example installs the adapter for NLog v4.1:

PM> Install-Package Common.Logging.NLog41

If you are using NLog v4.0, you should install the Common.Logging.NLog40 package and so on.

NB: Because NLog is using semver and the same strong name for every major version, Common.Logging.NLog40 and Common.Logging.NLog41 works for all NLog 4.x version. Common.Logging.NLog41 is the recommend version

The app config should then have a common logging section like below. Be sure to match the factoryAdapter type with your installed Common.Logging.NLogXX version.

<common>
    <logging>
      <factoryAdapter type="Common.Logging.NLog.NLogLoggerFactoryAdapter, Common.Logging.NLog41">
    	<arg key="configType" value="INLINE" />
      </factoryAdapter>
    </logging>
</common>

<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
...
</nlog>

Application Insights Quickstart

There are different packages for each major Application Insights version. Install the correct package for your referenced Application Insights version. This example installs the adapter for Application Insights v0.17:

PM> Install-Package Microsoft.ApplicationInsights -Version 0.17.0

The app config should then have an Application Insights section like below. Be sure to set the InstrumentationKey with your InstrumentationKey retrieved from Application Insights portal https://portal.azure.com.

<common>
    <logging>
      <factoryAdapter type="Common.Logging.ApplicationInsights.ApplicationInsightsLoggerFactoryAdapter, Common.Logging.ApplicationInsights">
    	<arg key="InstrumentationKey" value="[YOUR APPLICATION INSIGHTS INSTRUMENTATION KEY]" />
      </factoryAdapter>
    </logging>
</common>

See module documentation and Source Forge for other factoryAdapters and their configuration values
