nlog

I am using NLog for logging messages in .net core. I have added NLog in StartUp.cs as follows: loggerFactory.AddNLog(); For logging to file, I am using following method: logger.LogInformation("Message"); I want to add custom NLog event properties to my message. But LogInformation() is not allowing me to pass that. How can I do that? truemedia If you want custom layout properties (NLog calls them layout renderers) you can use the EventProperties Layout Renderer . You can simply do this in your code: var logger = LogManager.GetCurrentClassLogger(); var eventInfo = new LogEventInfo(LogLevel.Info,

算法的时间空间复杂度和空间复杂度总结 时间频度 一个算法中的语句执行次数称为语句频度或时间频度。记为T(n)。 如何获得T(n)： public static int factorial(int n){ int result = 1; //① if(n == 0 || n == 1){ //② return result; //③ }else{ for(int i = 2;i<=n;i++){ //④ result *= i; //⑤ } return result; //6 } } 上面的这个方法中，①语句执行一次；②虽然是if语句，但判断也需要执行一次；我们通常在计算算法效率时，做最坏打算，因此我们认为if不成立，执行else中的语句，④语句中包含三条语句，各执行了n-1次；⑤语句处于for循环中，执行了n-1次；⑥语句执行一次。因此，T(n)=1+1+4(n-1)+1=n-1 时间复杂度 一般情况下，算法中基本操作重复执行的次数是问题规模n的某个函数，用T(n)表示，若有某个辅助函数f(n),使得当n趋近于无穷大时，T(n)/f(n)的极限值为不等于零的常数，则称f(n)是T(n)的同数量级函数。记作T(n)=Ｏ(f(n)),称Ｏ(f(n)) 为算法的渐进时间复杂度，简称时间复杂度。 在上面已经提到了求T(n)的方法，现在我们只需要知道怎样通过T(n)求出f(n)

can any one provide me of a very sample custom layoutrenderer for nlog ? I want to make indentation while im logging , by example if im calling Method B from Method C the Text log file goes like this : Inside Method C Inside Method B and so on. Stacker here it is: [LayoutRenderer("IndentationLayout")] public sealed class IndentationLayoutRenderer : LayoutRenderer { // Value to substract from stack count private uint _ignore = 12; // Value to pad with. private string _ipadding = "| "; /// <summary>Set the number of (top) stackframes to ignore</summary> public uint Ignore { get { return _ignore;

I have two rules configured in NLog.config : <logger name="Model" level="Info" writeTo="modelLog" final="true" /> <logger name="*" minlevel="Debug" writeTo="logFile" /> I am trying to write to the first one, using the following code: LogEventInfo eventInfo = new LogEventInfo(); eventInfo.Level = LogLevel.Info; eventInfo.LoggerName = "Model"; eventInfo.TimeStamp = DateTime.Now; logger.Log(eventInfo); But it keeps falling through to the second rule. I would have thought eventInfo.LoggerName = "Model"; would have sent it straight to the first rule? wageoghe Not at computer now so can't try your

I have a need to capture the input and output of F# functions when using F# Interactive. I am able to get NLog to work just fine when the program is run under Visual Studio using F5 or Ctrl-F5. Also the same methods that contain statements to output to the log work just fine and are called when invoked via F# Interactive; just nothing in the log file. I also tried the following with F# Interactive to setup references to NLog and still nothing in the log when run from F# Interactive. #I @"..\packages\NLog.2.0.0.2000\lib\net40" #r @"NLog.dll" And I even found this which led me to try each of

考虑到项目后期添加日志的需求，抽个闲暇时间学习一下使用NLog插件将日志信息写入到数据库中，完整项目见下面； 遇到的问题： 使用NLog写到SQLServer里面的中文显示问号？ 解决方法：调整数据库的默认属性排序规则,两种方法： 方法一：手动修改（设置数据库的排序规则） 注意事项：要确定修改的数据库没有被使用，否则会失败！ 具体步骤：选中要修改的数据库-->右键-->属性-->弹出数据库属性对话框-->选项-->把排序规则设置成：Chinese_PRC_90_CI_AS-->确定。 方法二：使用代码修改 注意事项：要确定修改的数据库没有被使用，否则会失败！（将数据库连接断开执行这个脚本） 在查询分析其中输入 ALTER DATABASE 数据库名 COLLATE Chinese_PRC_CI_AS 2. 为什么数据库的排序规则会影响到中文的显示？ 自己看了一片较少挺详细的： 点我查看哦！ 完整测试项目： 请点击这里！ 版权声明：本文为博主原创文章，如需转载，请标明出处。 来源： https://www.cnblogs.com/gamecc666/p/11453000.html

I have a windows service and use nlog for logging. Everything works fine when I run from the visual studio ide. The log file updates with no issues. When I install the service, the service runs fine but the log file never updates. I am running under LOCAL SERVICE if that helps. Yes, I have created the logs directory under my application folder. <?xml version="1.0" encoding="utf-8" ?> <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > <targets> <target name="file" xsi:type="File" fileName="${basedir}/logs/${shortdate}_info.txt"

前言 现实开发中有许多的延迟操作，比如定时清理过期数据等，在JDK中自带的Timer或者DelayQueue来实现延迟的功能，但很多开源的中间件中并没有使用Timer或者DelayQueue来实现而是使用基于时间轮算法来实现执行延迟任务功能，例如2.7.0以上的Dubbo基于时间轮实现了，失败定时重发，心跳检测等延迟操作。JDK的Timer和DelayQueue插入和删除操作的平均时间复杂度为O(nlog(n))并不能满足的高性能插入删除的要求，而而基于时间轮可以将插入和删除操作的时间复杂度都降为O(1) 。 实现 时间轮是参考钟表盘来实现，钟表盘上的表针会在固定时间后向前走一格，走完12格后又回到原来位置重复上面流程，时间轮也类似定义了几个格，在固定时间在这几个格上走动。盗图看下结构 如上图，时间轮有多个时间格组成，每个时间格里放置了任务队列，当走到某个时间格时会执行当前时间格里的任务。时间轮的每个时间格用slot表示，时间轮的时间格长度是固定的用wheelLength表示，每个时间格走动的间隔时间也是固定的用tickDuration表示，假设当前指向时间格的第一个位置，要执行一个延迟时间为deadline的任务，那么需要先找到对应的slot将任务加入才能顺利执行，其对应的计算公式：slot = (deadline / tickDuration)%wheelLength

Note: Updated with suggested improvements, closer but still not quite there! Similar to this question - Passing in the type of the declaring class for NLog using Autofac - I am trying to inject NLog instances into my repository classes. Interface: public interface ILogger<T> where T: class { ... } Implementation: public class NLogger<T> : ILogger<T> where T: class { private readonly Logger _logger; public NLogger() { _logger = LogManager.GetLogger(typeof(T).FullName); } public void Debug(string message) { _logger.Debug(message); } ... } Registered with Autofac as: builder.RegisterGeneric
