Targets

##Use Targets are used to display, store, or pass log messages to another destination. There are two kinds of target; those that receive and handle the messages, and those that buffer or route the messages to another target. The second group are called 'wrapper' targets.

##Supported Targets

• AspResponse - Outputs log messages through the ASP Response object.
• Chainsaw - Sends log messages to the remote instance of Chainsaw application from log4j.
• ColoredConsole - Writes log messages to the console with customizable coloring.
• Console - Writes log messages to the console.
• Database - Writes log messages to the database using an ADO.NET provider.
• Debug - Mock target - useful for testing.

• Trace - Sends log messages through System.Diagnostics.Trace.
• WebService - Calls the specified web service on each log message.

##Wrapper Targets

• AspNetBufferingWrapper - Buffers log events for the duration of ASP.NET request and sends them down to the wrapped target at the end of a request.
• AsyncWrapper - Provides asynchronous, buffered execution of target writes.
• AutoFlushWrapper - Causes a flush after each write on a wrapped target.
• BufferingWrapper - A target that buffers log events and sends them in batches to the wrapped target.
• FallbackGroup - Provides fallback-on-error.
• FilteringWrapper - Filters log entries based on a condition.
• ImpersonatingWrapper - Impersonates another user for the duration of the write.
• PostFilteringWrapper - Filters buffered log entries based on a set of conditions that are evaluated on a group of events.
• RandomizeGroup - Sends log messages to a randomly selected target.
• RepeatingWrapper - Repeats each log event the specified number of times.
• RetryingWrapper - Retries in case of write error.
• RoundRobinGroup - Distributes log events to targets in a round-robin fashion.
• SplitGroup - Writes log events to all targets.

##Custom Targets RabbitMQ target (NuGet) - sends logs over a RabbitMQ message broker. It allows you to combine your logs in real time across multiple platforms and systems.

NLog supports custom target. For more information, see: How to write a Target
