nlog

问题 NLog has an internal log that the developer can use to troubleshoot issues with logging. Does Enterprise Library Logging have anything like that that I can use to figure out why my log messages aren't going anywhere? 回答1: There's a "Logging Errors and Warnings" special category. If there's a problem with the logging infrastructure itself, it'll get logged there. You can point this at any trace listener - by default it goes to the Windows event log. Of course, if you have a problem with the

问题 I am using NLog for DB logging. If the DB is down then I only need it to log to a file. Is there a way to do this? I don't want to record log entries log in both a file and the DB. If the DB target fails to log (if DB is down) only then do I have to log to the file. Is there any fail over or fallback feature with Nlog? 回答1: Yes, there is a way. It's called a FallbackGroup . Documentation can be found here: https://github.com/nlog/NLog/wiki/FallbackGroup-target Here is an example taken

问题 I get the error at the end when I try to start a project I'm working on from Visual Studio. It worked fine until a few hours ago. After some minor unrelated changes it stopped working when starting from Visual Studio. It works fine when run from explorer. Even old version vom revision control (where this part of the code is exactly the same and has worked without any problems) behave the same way so it doesn't seem to be a problem in my code. The code at Program.cs:line 14 is the following:

问题 So, I have library shared among more executables. If I understand properly, I cannot attach config to library directly like library.dll.nlog, but I have to use config per exe or use nlog.config for global settings. (It's ok to log from more places into single log.) Here we come with few more executables that don't use this dll and it is required to log into different log files, so, I can use config per exe like app.exe.nlog. It works flawlessly, until placed in directory with nlog.config file

问题 This is my config for nlog. What i'm trying to achieve is to have Quartz logs in separate file. But checking the logs folder i find only scheduler log file. <targets> <target xsi:type="File" name="f" fileName="${basedir}/logs/log-${shortdate}.log.json" layout="${json}" /> <target xsi:type="File" name="scheduler" fileName="${basedir}/logs/log-${shortdate}.scheduler.log" layout="${message}" /> <target xsi:type="Console" name="console" layout="${longdate} ${uppercase:${level}} ${message}" /> <

问题 I see a lot of posts mentioning usage of Microsoft.Extensions.Logging together with NLog. I'd like to better understand what Microsoft.Extensions.Logging is used for? And specifically why is it needed or what's the benefit of using it together with NLog? 回答1: With NLog you could do: var logger = NLog.LogManager.GetCurrentClassLogger(); logger.Info("Hello {Name}", "Earth"); That works for all platforms and all frameworks. Microsoft.Extensions.Logging With the introduction of .NET Core, a

问题 I'm working on setting up NLogs in the most useful way possible for our web applications My thought process is as follows A new request is initiated A new guid is generated Log webapi events w/the guid Log service layer events w/the guid A new guid is generated for the next request This way it will be easy to trace the full series of events from request start to finish There are also scenarios where I'm running service methods in parallel, if threads affect this solution I've tried setting up

问题 Want to try nosql and need to improve logging (write to some DB instead of files..). For now i use SQLCE for that. Can i use NLog and write to RavenDB for example? If 'yes' please provide some sample NLog configuratoin file. Thank you. 回答1: Yes, you can do that, but you would have to write the appender that does this yourself, I don't think there is an OOTB appender for this. 来源： https://stackoverflow.com/questions/9390922/can-nlog-write-to-ravendb-database

问题 i am using the NLog built in support for castle and trying to find a way to alter the connection string at run time. this is my latest swing and miss, im sure it has to do the life cycle at this point as all of the configuration is null so i am guessing that castle has not yet wired up the guts on NLog. private const string NLogConnectionString = "NLogConnection"; public void Install(IWindsorContainer container, IConfigurationStore store) { container.AddFacility<LoggingFacility>(l => l
