我有一个进程在 Windows 服务器上运行,多个用户在多个会话上运行(可能有多达 50 个并发用户),我想:
所以我想我应该尝试一下 nLog:
<?xml version="1.0" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
internalLogFile="file.txt">
<targets async="false">
<target name="regFile" xsi:type="File"
layout="${longdate} [${windows-identity}][${processid}]${threadname} ${uppercase:${level}} ${callsite} - ${message}${onexception:${newline}${exception:format=tostring}}"
fileName="${basedir}/logs/test.log"
archiveFileName="${basedir}/logs/test.{#####}.log"
archiveAboveSize="102400"
archiveNumbering="Rolling"
maxArchiveFiles="14"
concurrentWrites="true"
keepFileOpen="true"
autoFlush="true"
/>
</targets>
<rules>
<logger name="*" minlevel="Trace" writeTo="regFile" />
</rules>
</nlog>

我还写了一个小测试器:
class Program
{
private static Logger m_log = LogManager.GetCurrentClassLogger();
static void Main(string[] args)
{
// Load logger configuration
var assemblyLocation = Assembly.GetExecutingAssembly().Location;
var assemblyDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
if (assemblyDirectory != null)
{
var logConfig = new FileInfo(Path.Combine(assemblyDirectory, "nlogConfig.xml"));
NLog.LogManager.Configuration = new NLog.Config.XmlLoggingConfiguration(logConfig.FullName, true);
}
if (args.Length == 1)
{
var sw = Stopwatch.StartNew();
var size = Int32.Parse(args[0]);
m_log.Info("Will launch {0} process and wait for them to come back...",size);
var handles = new WaitHandle[size];
for (int i = 0; i < size; i++)
{
var p = Process.Start(Assembly.GetExecutingAssembly().Location);
var processHandle = OpenProcess(
ProcessAccessFlags.Synchronize, false, p.Id);
if (processHandle != IntPtr.Zero)
handles[i] = new ManualResetEvent(false)
{
SafeWaitHandle = new SafeWaitHandle(processHandle, false)
};
m_log.Fatal("Started pid={0}.",p.Id);
}
m_log.Info("Created the processes, now wait.");
WaitHandle.WaitAll(handles);
sw.Stop();
Thread.Sleep(100);
m_log.Info("Done, took {0}.",sw.ElapsedMilliseconds);
}
else
{
m_log.Info("Running for {0} * {1}",1000,m_log.ToString());
for (int i = 0; i < 1000; i++)
{
m_log.Error("Hello nlog {0}", i);
}
}
}

运行得很好,只要我不需要存档...运行我的测试器如下:“LoggerTester.exe 10”我得到
也许我要求太多,我必须使用某种内存记录器模式(用 1 个记录器来实际管理文件),但我真的不希望这样做。
在任何地方都找不到任何对此的参考,所以我想我在这里试试运气......谢谢。
我认为您将无法从多个进程登录到单个文件。我建议尝试其他一些目标:
我过去曾成功使用 DatabaseTarget。
我没有其他目标的经验,但我确实实现了一次 LoggingService 。它与 LogReceiverWebServiceTarget 非常相似。它是一个实现日志记录接口的 WCF 服务。我们有一个相应的目标,可以将其配置为与日志记录服务端点进行通信。我们还实现了一些缓存和刷新,以便我们发送消息块,而不是为每条消息进行服务调用。
祝你好运!
