We have a Windows Service that kicks off another process called ClusterProcess.
I want to get logs from the Windows Service and from the ClusterProcess, and I want those logs to go to the database and to files. For instance, if the database is not accessible, I want to be able to see the logs in the files.
I have an external config file for the Log4Net settings. There are two RollingFileAppenders and two AdoNetAppenders.
There is the default root logger and an additional logger called, ClusterProcessLogger.
The idea is that the Windows Service uses the root logger and logs to one of the AdoNetAppenders and one of the RollingFileAppenders, and that the ClusterProcess uses the ClusterProcessLogger and logs to the other AdoNetAppender and the other RollingFileAppender.
The AdoNetAppenders for both cases work fine. The RollingFileAppenders do not.
So here is the external config file for the log4net configuration:

I don't know what to do about the first error.
The second and third error shouldn't be there. The ClusterProcess should be able to access the SpecialCalcEngineLog.txt, and it shouldn't be bothered with the CalcEngineLog.txt, as that is the RollingFileAppender that the Windows Service is using.
How do I solve these errors? What am I overlooking?
First error can be mitigated by adding
<configSections>
<section name="log4net" type="System.Configuration.IgnoreSectionHandler" />
</configSections>
somewhere.
Multiple RollingFileAppenders cannot write to the same file. However, you can distinguish by, for example, adding process id to the file name (and then collect logs from all processes):
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="C:\log\logfile_[%processid].log" />
...

I'm trying to implement logging with log4net in an asp.net core console app. I have a business library written in .net 4.7.1 with a logging wrapper that I'm using to do logging in all of my apps. I have a file appender, a console appender, an smtp appender, and an ado.net appender. All of these work on my asp.net core web app and they also work in my non-core console apps.
Only the console and file appenders work in .net core console. The ado.net and email appenders do not seem to work. I don't get emails and nothing is inserted into the DB.
This is my Main method:
static void Main(string[] args)
{
// Set up DI
var serviceProvider = new ServiceCollection()
.AddSingleton<IRepository, Repository>()
.AddSingleton<ITdnLogger, TdnLogger>()
.BuildServiceProvider();
var logger = serviceProvider.GetService<ITdnLogger>();
logger.Log(LoggingLevel.Info, "This is a test log error!");
var logga = new TdnLogger();
logga.Log(LoggingLevel.Error, "Error but not an error");
Console.ReadLine();
}
I first attempt to get the logger to log using dependency injection and then I instantiate a new one and try again. I get the same results both times. Console and File appenders work, email and ado do not. So I'm thinking it has nothing to do with DI, but is probably more of a set up issue. I don't understand where the setup could be wrong, because it works for everything else, but...
In my business library's AssemblyInfo.cs I have the log4net config set up like this:

Any ideas of why the ado and email appenders might not work in a core console app?
EDIT #1:
I got the email appender to work, I had the email address setup incorrectly.
The ado appender is throwing this error:
System.TypeLoadException: Could not load type
System.Runtime.Remoting.Messaging.CallContext from assembly 'mscorlib,

Try using https://github.com/microknights/Log4NetAdoNetAppender, instead of the standard log4net.Appender.AdoNetAppender. You will need to change the appender type definition in your config file to:
MicroKnights.Logging.AdoNetAppender, MicroKnights.Log4NetAdoNetAppender
as per the documentation on their project page.
I have problem with log4net. In localhost works fine and save in the database (Production1), then in QA not save the log in the same database (Production1)

I review in QA and have the same web.config.
Can someone off a 2nd set of eyes? I am clearly missing something.
I'm using Log4Net in a Web API app. Whenever I invoke a Log.Error() it executes, but nothing actually gets written to my dbo.Log table. I am running a local database. When I replaced the configuration with one that wrote to a file, the code worked perfectly.
Here is what my configuration and code looks like.
The Log4Net.config file contains the following:

The Global.asax.cs file contains the following, note the call to the Log4Net.Config() method which specifies which config to use.
public class WebApiApplication : System.Web.HttpApplication
{
private static readonly log4net.ILog Log = log4net.LogManager.GetLogger(typeof(WebApiApplication));
protected void Application_Start()
{
log4net.Config.XmlConfigurator.Configure(new System.IO.FileInfo(Server.MapPath("Log4Net.config")));
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
}
}
The initialization of the logger in my Controller is:
public class FitDashboardController : ApiController
{
private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
IFitDashboardService fitDashboardService = new FitDashboardService();
...
And the call is:
catch (System.Exception ex)
{
log.Error("Error:" + MethodBase.GetCurrentMethod().Name + " :: " + ex.Message);
}
Again, the code works when writing to a file, but not the database. Any ideas?
This question has been answered here. The problem is your <bufferSize> tag, which according to the linked answer...
<bufferSize value="100" />
It is saying that it will keep 100 logs in
memory until written into DB. Maybe that's why you don't see anything
in DB?
Change your code to say <bufferSize value="1" /> and this should cause log4net to write to your database after keeping 1 log in memory. See Apache's documentation on buffersize for more details.
Have you tried running sql server profiler and doing a trace against the database in the connection string? The insert statement log4net submits should show up along with values for the various parameters.
I am trying to configure log4net to log in the database, it is already configured to write in a file, but when I change the appender to the database it doesn't do anything. The connection to the database is ok because if I change the password I can see an entry in the eventviewer saying the password is wrong.
Here it is my app.config:

Any guess?
Do I need to create the database and the table manually or it will be automatically created?
You need to create the database and the Log table yourself.
If you want to diagnose possible issues with log4net, you can create a diagnostic trace by adding this to your .config file:
<system.diagnostics>
<trace autoflush="true">
<listeners>
<add
name="textWriterTraceListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="C:\whatever\your\path\is\log4net.txt" />
</listeners>
</trace>
</system.diagnostics>
and adding the debug switch:
<appSettings>
<add key="log4net.Internal.Debug" value="true"/>
</appSettings>
I have Web API that needs to write log data, both to a file and to the database.
Is it possible to configure such a setup? I am trying to understand ILoggerRepository but I am confused.
Can someone give me the some tips on how to configure it and how to use it in application?
It sounds to me like you want to write to two different style appenders at the same time.
The good news is that this is built right into the log4Net library.
What you want to do so configure you configuration file to two different appenders. A file Appender and a Database appender.
Examples of the different appenders can be found here.
http://logging.apache.org/log4net/release/config-examples.html
Here is an example of an web.config that i whipped together. You are going to have to tweak it to get it to work for you, but it will get you on the right start.
One last point, your log4net configuration does not have to be in your web.config but IMHO it just makes things easier to get started. Worry about breaking it out once your web.config starts to get a little cluttered.
