RoundRobinGroupTarget Class |
Namespace: NLog.Targets.Wrappers
The RoundRobinGroupTarget type exposes the following members.
Name | Description | |
---|---|---|
RoundRobinGroupTarget |
Initializes a new instance of the RoundRobinGroupTarget class.
| |
RoundRobinGroupTarget(Target) |
Initializes a new instance of the RoundRobinGroupTarget class.
| |
RoundRobinGroupTarget(String, Target) |
Initializes a new instance of the RoundRobinGroupTarget class.
|
Name | Description | |
---|---|---|
IsInitialized |
Gets a value indicating whether the target has been initialized.
(Inherited from Target.) | |
LoggingConfiguration |
Gets the logging configuration this target is part of.
(Inherited from Target.) | |
Name |
Gets or sets the name of the target.
(Inherited from Target.) | |
SyncRoot |
Gets the object which can be used to synchronize asynchronous operations that must rely on the .
(Inherited from Target.) | |
Targets |
Gets the collection of targets managed by this compound target.
(Inherited from CompoundTargetBase.) |
Name | Description | |
---|---|---|
CloseTarget |
Closes the target to release any initialized resources
(Inherited from Target.) | |
Dispose |
Closes the target.
(Inherited from Target.) | |
Dispose(Boolean) |
Releases unmanaged and - optionally - managed resources.
(Inherited from Target.) | |
Flush |
Flush any pending log messages (in case of asynchronous targets).
(Inherited from Target.) | |
FlushAsync |
Flush any pending log messages for all wrapped targets.
(Inherited from CompoundTargetBase.) | |
InitializeTarget |
Initializes the target before writing starts
(Inherited from Target.) | |
PrecalculateVolatileLayouts |
Calls the Precalculate(LogEventInfo) on each volatile layout
used by this target.
This method won't prerender if all layouts in this target are thread-agnostic.
(Inherited from Target.) | |
RenderLogEvent(Layout, LogEventInfo) |
Renders the logevent into a string-result using the provided layout
(Inherited from Target.) | |
RenderLogEventT(LayoutT, LogEventInfo, T) |
Renders the logevent into a result-value by using the provided layout
(Inherited from Target.) | |
ResolveServiceT |
Resolve from DI ServiceRepository (Inherited from Target.) | |
ToString | Returns a string that represents the current object. (Inherited from CompoundTargetBase.) | |
Write(AsyncLogEventInfo) |
Forwards the write to one of the targets from
the NLog.Targets collection.
(Overrides TargetWrite(AsyncLogEventInfo).) | |
Write(IListAsyncLogEventInfo) |
Writes an array of logging events to the log target. By default it iterates on all
events and passes them to "Write" method. Inheriting classes can use this method to
optimize batch writes.
(Inherited from Target.) | |
Write(LogEventInfo) |
Writes logging event to the target destination
(Inherited from CompoundTargetBase.) | |
WriteAsyncLogEvent |
Writes the log to the target.
(Inherited from Target.) | |
WriteAsyncLogEvents(AsyncLogEventInfo) |
Writes the array of log events.
(Inherited from Target.) | |
WriteAsyncLogEvents(IListAsyncLogEventInfo) |
Writes the array of log events.
(Inherited from Target.) | |
WriteAsyncThreadSafe(AsyncLogEventInfo) |
Ensures forwarding happens without holding lock
(Overrides TargetWriteAsyncThreadSafe(AsyncLogEventInfo).) | |
WriteAsyncThreadSafe(IListAsyncLogEventInfo) |
Writes an array of logging events to the log target, in a thread safe manner.
Any override of this method has to provide their own synchronization mechanism.
!WARNING! Custom targets should only override this method if able to provide their
own synchronization mechanism. Layout-objects are not guaranteed to be
thread-safe, so using them without a SyncRoot-object can be dangerous.
(Inherited from Target.) | |
WriteFailedNotInitialized |
LogEvent is written to target, but target failed to successfully initialize
(Inherited from Target.) |
This example causes the messages to be written to either file1.txt or file2.txt. Each odd message is written to file2.txt, each even message goes to file1.txt.
To set up the target in the configuration file, use the following syntax:
1<?xml version="1.0" ?> 2<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 4 <targets> 5 <target name="file" xsi:type="RoundRobinGroup"> 6 <target xsi:type="File" fileName="${basedir}/file1.txt" /> 7 <target xsi:type="File" fileName="${basedir}/file2.txt" /> 8 </target> 9 </targets> 10 11 <rules> 12 <logger name="*" minlevel="Debug" writeTo="file" /> 13 </rules> 14</nlog>
To set up the log target programmatically use code like this:
1using System; 2 3using NLog; 4using NLog.Targets; 5using NLog.Targets.Compound; 6using System.Diagnostics; 7 8class Example 9{ 10 static void Main(string[] args) 11 { 12 FileTarget file1 = new FileTarget(); 13 file1.FileName = "${basedir}/file1.txt"; 14 15 FileTarget file2 = new FileTarget(); 16 file2.FileName = "${basedir}/file2.txt"; 17 18 RoundRobinTarget target = new RoundRobinTarget(); 19 target.Targets.Add(file1); 20 target.Targets.Add(file2); 21 22 NLog.Config.SimpleConfigurator.ConfigureForTargetLogging(target, LogLevel.Debug); 23 24 Logger logger = LogManager.GetLogger("Example"); 25 logger.Debug("log message"); 26 } 27}
