Delete log files after x days

阅读更多关于 Delete log files after x days

I would like to log with Nlog using the file target like in this example . How can I realize a deletion of the files after X days without archiving them? Or is it possible to archive the files to the same folder? ccellar You could simply use the built-in archiving functionality. This setting will keep 7 old log files in addition to your current log. The cleanup is done by NLog automatically. <?xml version="1.0" ?> <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" layout="${longdate} $

Add / remove logfiles during runtime in NLog

阅读更多关于 Add / remove logfiles during runtime in NLog

I'm writing a small file conversion utility. Files get automatically converted when they are dropped into a directory. I'm using NLog for logging. Besides a central log file which is configured using NLog.conf (and which receives all messages generated), I'd like to create one additional log file for each input file, having a similar name and containing all log messages written during the conversion process. Unfortunately I seem to be unable to find out how to properly add a new file target together with the appropriate rule during runtime. I want all Logger objects to write to the new log

阅读更多关于 Adding properties to log message in NLog in .net core

问题 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? 回答1: 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:

When should I use Tracing vs Logger.NET, Enterprise Library, log4net or Ukadc.Diagnostics?

Nlog - Generating Header Section for a log file

阅读更多关于 Nlog - Generating Header Section for a log file

Just recently got into experimenting with NLog, and it occurs to me that I would like to be able to add header information to the top a log file such as: Executable name File version Release Date Windows User ID etc... After some searching I have been unable to find anything in the existing on-line documentation or code forums which indicates this type of functionality. Is this possible? I have always previously included this sort of information in log files, and have found it useful on numerous occsions in the past, when sourcing information on production issues at customer sites. Admittedly,

How can I use NLog's RichTextBox Target in WPF application?

阅读更多关于 How can I use NLog's RichTextBox Target in WPF application?

How can I use RichTextBox Target in WPF application? I don't want to have a separate window with log, I want all log messages to be outputted in richTextBox located in WPF dialog. I've tried to use WindowsFormsHost with RichTextBox box inside but that does not worked for me: NLog opened separate Windows Form anyway. If you define a RichTextBoxTarget in the config file, a new form is automatically created. This is because NLog initializes before your (named) form and control has been created. Even if you haven't got any rules pointing to the target. Perhaps there is a better solution, but I

How to integrate NLog to write log to Azure Streaming log

阅读更多关于 How to integrate NLog to write log to Azure Streaming log

问题 Currently I am using NLog to write my application errors to a text file. How can I configure NLog to write the error messages to Azure Streaming Log apart from writing to a Azure Blob Storage? 回答1: the Azure Streaming Log captures what is sent to the Trace interface. If you configure NLog to send to that target, you can then easily access that through the output window in Visual Studio for instance. Here is how I configured NLog.config to obtain this result: <targets> <target xsi:type="File"

What is the difference between log4net.ThreadContext and log4net.LogicalThreadContext?

阅读更多关于 What is the difference between log4net.ThreadContext and log4net.LogicalThreadContext?

UPDATED on 11/18/2014 - While browsing the log4net source repository, I found that the implementation of LogicalThreadContext was modified in November 2011 to that it stores its properties using CallContext.LogicalSetData (and gets them using LogicalGetData). This is important because that means that LogicalThreadContext should now work correctly. Any data stored in LogicalThreadContext should be "flowed" to any child threads or tasks. This compares to ThreadContext (and the old implementation of LogicalThreadContext) where data stored in the context would remain local to the current thread
