I want use Log4Net in my application for logging to console and database(Oracle)
I made this setting :
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="[%thread] - Level%newline - %level%newlineMessage - %message%newlineUTC Date - %utcdate{ABSOLUTE}%newlineDate - %date{ABSOLUTE}%newline%newline "/>
</layout>
</appender>
<appender name="AdoNetAppender_Oracle" type="log4net.Appender.AdoNetAppender">

On console I have output, but after start there is some Exception thrown: 'Oracle.ManagedDataAccess.Client.OracleException' in Oracle.ManagedDataAccess.dll
And of course there is no new line in Oracle table.
Any suggestion why not working ?
Thank you.
This is a working configuration for my custom table but you can use the default columns. Pay attention on which OracleDataAccess use in your application (Version=2.121.2.0) Check here AdoNetAppender.ConnectionType Property
<appender name="DatabaseAppender" type="log4net.Appender.AdoNetAppender">

I have been using log4net to log to an Oracle database for the past few weeks and everything was working until I was told that Native Network Encryption had been turn on. This caused my logging to cease and I'm clueless on how to fix it. No errors are given, it just won't write to the DB. I am using the following logger.xml file:
<log4net>
<appender name="DebugAppender" type="log4net.Appender.DebugAppender">

As I said this was working perfectly until NNE was turned on. The application I am using is a C# console app. Can anyone point me in the right direction?
my code seems to be working but it does not write anything to my logs file I edited the location of files but it still does not work I don't know where my errors are because it does not pop up
my this is the contents of my app config

and the contents of my system codes are
using log4net;
private void q_Click(object sender, EventArgs e)
{
log.Info("Your data has been successfully saved");
}
private void w_Click_1(object sender, EventArgs e)
{
int x = 0;
try
{
int y = 1 / x;
}
catch(Exception ex)
{
log.Error(ex.Message, ex);
}
}
what I want to see is that there are logs in my database, and I also did create a file that has the values from above so I'm wondering where are the problem in my codes
I am currently using Log4net to log in a table but I need to stop using that table and log everything in another table for logging errors. Basically I just changed the log4net values and parameters and the table in which I am logging. Here is the Log file

The problem is, it's not logging in the ProviderHistoryLog table. It's not logging anything. As you can see the value for the buffer size is 1 so I am thinking the issue is in the INSERT INTO statement.
I have a problem with the AdoNetAppender of log4net in my ASP.NET Core application (netcoreapp1.1).
If I want to use the AdoNetAppender, I get the following error:
System.TypeLoadException: Could not load type 'log4net.Appender.AdoNetAppender' from assembly 'log4net, Version=2.0.8.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a'.
Is there anybody who have the AdoNetAppender running under ASP.NET Core (netcoreapp1.1)? If not, is there a good alternative to log with log4net into a database? I also use Entity Framework Core.
The AdoNetAppender isn't supported at present on .NET Core 1.0 / .NET Standard 1.3: https://logging.apache.org/log4net/release/framework-support.html#Appenders
For .Net Core you can use nuget.org/packages/MicroKnights.Log4NetAdoNetAppender . It has a bit differences in set up compare to AdoNetAppender, but is very straightforward too, to Find how to set it up here: github.com/microknights/Log4NetAdoNetAppender
Here an example that works for me
<appender name="AdoNetAppender" type="MicroKnights.Logging.AdoNetAppender, MicroKnights.Log4NetAdoNetAppender">
<bufferSize value="1" />
<connectionType value="System.Data.SqlClient.SqlConnection,System.Data.SqlClient,Version=4.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089" />
<connectionStringName value="log4net" />
<connectionStringFile value="appsettings.json" />
<commandText value="INSERT INTO Log ....." />
<parameter>
<parameterName value="#log_date" />
<dbType value="DateTime" />
<layout type="log4net.Layout.RawTimeStampLayout" />
</parameter>
<parameter>
<parameterName value="#thread" />
<dbType value="String" />
<size value="255" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%thread" />
</layout>
</parameter>
<parameter>
<parameterName value="#log_level" />
<dbType value="String" />
<size value="50" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%level" />
</layout>
</parameter>
<parameter>
<parameterName value="#logger" />
<dbType value="String" />
<size value="255" />

</parameter>
<parameter>
<parameterName value="#message" />
<dbType value="String" />

</parameter>
<parameter>
<parameterName value="#exception" />
<dbType value="String" />
<size value="2000" />
<layout type="log4net.Layout.ExceptionLayout" />
</parameter>
</appender>
and in your appsettings.json
"ConnectionStrings": {
"log4net": "Data Source=.\\SQLEXPRESS;Initial Catalog=LogDB;User ID=user;Password=pass",
}
I have multiple appenders in my log4net configuration, one for logging to a file, and the other using a stored procedure. I'm able to see the logging to a file, but the SQL data will show only after I click "Stop Site", see the image below:
So I've come to the conclusion that I may have to 'shutdown' the instance by doing the following: log4net.LogManager.GetLogger("SearchParamsLogger").Logger.Repository.Shutdown();
But in doing so, it seems to also shut down the other logger. How can I shut down only the ONE logger?
I have the following logger blocks:
<logger name="SearchParamsLogger">
<level value="DEBUG" />
<appender-ref ref="LogSearchParams" />
</logger>
<logger name="FileLogger">
<level value="DEBUG" />
<appender-ref ref="LogFile" />
</logger>
I have the following appenders in my .config:
<appender name="LogSearchParams" type="log4net.Appender.AdoNetAppender">
<bufferSize value="100" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

You can configure the number of messages the DBAppender will buffer before flushing them to the DB.
Your <bufferSize value="100" /> is the default example I found here, lower it and you should see the messages more often, you can even get immediate logging to the DB with the value 1 (or lower)
