I'm trying to save any logs I received from the application into a log table in my db and so far, nothing gets saved. I'm using Log4net and AdoNetAppender for saving the logs into my table inside SQL Server. This code sits inside a Web API project on the server side of my app.
I set up the logs as follows:
1) Setup the XML in my Web.Config:
<log4net>
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="1" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=token" />

<appender-ref ref="asyncForwarder" />
</root>
</log4net>
2) Here's the code inside my Global.asax.cs:
public class WebApiApplication : System.Web.HttpApplication
{
private static readonly ILog _log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
protected void Application_Start()
{
XmlConfigurator.Configure();
_log.Info("Service Started");
GlobalConfiguration.Configure(WebApiConfig.Register);
}
public static void Register(HttpConfiguration config)
{
// Web API routes
config.MapHttpAttributeRoutes();
}
}
3) Added the Stored Procedure to the db:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE dbo.procLogs_Insert
#log_timestamp datetime,
#log_recordNum int,
#log_computerName varchar(128),
#log_processTimeStamp datetime,
#log_group char(1),
#log_type char(1),
#log_eventId int,
#log_userId varchar(128),
#log_line int,
#log_description text,
#log_source text,
#log_data text,
#log_addTimeStamp datetime,
#log_deviceId char(10)
AS
BEGIN
SET NOCOUNT ON;
insert into dbo.BS_ApplicationLogs(LogTimestamp, RecordNum, ComputerName, ProcessTimestamp, LogGroup, [Type],EventId,UserId,Line,[Description],[Source],[Data],AddTimestamp,DeviceID)
values (#log_timestamp, #log_recordNum, #log_computerName, #log_processTimeStamp, #log_group, #log_type, #log_eventId, #log_userId, #log_line,#log_description,#log_source,#log_data,#log_addTimeStamp,#log_deviceId)
END
GO
Question: Where should this stored procedure be saved in SSMS? When I save the stored procedure, it automatically defaults it to Documents\SSMS but I want to save it under DB/Programmability/StoredProcedures folder but I don't see it there. However, I did execute the stored procedure successfully without any errors.
4) added logs to other files inside my app project outside of the global.asax.cs file. Does Log4Net know to log those as well?
So yeah I'm not sure what I did wrong and nothing gets logged to my table in SQL Server. Did I miss a step in the process of setting up Log4Net?
EDIT: Internal debugger says:
log4net: Created Appender [AdoNetAppender]
log4net: Created Appender [asyncForwarder]
log4net: Adding appender named [asyncForwarder] to logger [root].
log4net: Hierarchy Threshold []
log4net:ERROR [AdoNetAppender] ErrorCode: GenericFailure. Exception while writing to database

What key?
3) Sounds like you've created the Stored Procedure, however its ended up in the Master database (Master/Programmability/StoredProcedures).
You should either select the DropDownList and change from Master to your DB or you can use the syntax USE YourDB before the stored proc and click the Execute button:
USE YourDB
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

#log_recordNum int,
#log_computerName varchar(128),

#log_eventId int,
#log_userId varchar(128),
#log_line int,
#log_description text,
#log_source text,
#log_data text,
#log_addTimeStamp datetime,
#log_deviceId char(10)
AS
BEGIN
SET NOCOUNT ON;
insert into dbo.BS_ApplicationLogs(LogTimestamp, RecordNum, ComputerName, ProcessTimestamp, LogGroup, [Type],EventId,UserId,Line,[Description],[Source],[Data],AddTimestamp,DeviceID)

END
GO
This is a file I have that works, writing to a MS SQL server
It refers to user defined properties %property{xxx}, that are populated in code like this
GlobalContext.Properties["user"] = Environment.UserName;
Maybe you can replace some of your properties with that to figure out which one is causing the issue

I am having a controller, where I inject the log4net dependency like this:
public CalendarController(ILogger<CalendarController> logger) : base(logger) { }
[HttpGet]
public List<MyClass> Get()
{
var log = new
{
Message = "asd123",
LogLevel = "Error",
LogDate = DateTime.Now,
EndpointName = "testendpoint",
Username = "myusername",
Userdomain = "mydomain"
};
_logger.LogError(JsonConvert.SerializeObject(log));
return someValue;
}
My db structure looks like this:
The log4net.config file looks like this:

I thought RawProperty layouts is the thing I want, but it is not. How can I configure this XML, so that the parameters I gave to _logger.LogError() are correctly inserted into the database?
In properties of log I noticied all the level logs (IsErrorEnabled) have value false, in log.Logger.Repository.Configured has value false.
I dont know if LogManager can't find the log4net node in app.config or there's something wrong in xml.
I'm trying:
[TestMethod]
public void TestLog()
{
ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
log.Debug("teste");
}
Before, I used Sql and all worked perfectly, but since I changed to MySql the logs dont work anymore.
Can anyone help me?
This is my XML

I'm find the errors.
Thanks [stuartd] for reply.
First I forget the XmlConfigurator.Configure()
After I enable the log4net debug by:
<add key="log4net.Internal.Debug" value="true"/>
<system.diagnostics>
<trace autoflush="true">
<listeners>
<add
name="textWriterTraceListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="C:\tmp\log4net.txt" />
</listeners>
</trace>
</system.diagnostics>
So Log4net logged the error:
The command text was wrong
"INSERT INTO LogServico ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (#log_date, #thread, #log_level, #logger, #message, #exception);"
The rigth way is:
"INSERT INTO LogServico (Date,Thread,Level,Logger,Message,Exception) VALUES (?log_date, ?thread, ?log_level, ?logger, ?message, ?exception);"
And change all parameter name to ?name like:
<parameterName value="?log_date" />
So my final app.config is:
<log4net>
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">

My funcional method test:
[TestMethod]
public void TestLog()
{
log4net.Config.XmlConfigurator.Configure();
ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
log.Error("test", new Exception("test"));
}
It's important remember all that is to log in mysql. In Sql the command text can use [namecolumn] and the parameter has #nameparameter
There are a number of possible reasons:
Your log4net config file is not set to "Copy Local" on build
You are not initialising log4net (ie calling XmlConfigurator.Configure or using an assembly attribute).
Your config is invalid.
As you say this worked previously, then it seems probable that it is 3, and your config is invalid.
im trying to enter every 100 records into the database.If i specify the buffer size as 100.It stills enters each record into the database.Is there a way where i can specify the flush interval and buffer size.So which comes first it takes that.

Buffersize only specifies how many items shall be kept in RAM before committing them. It does not define the Lossyness of the logger.
To define a lossy logger, you need to state that explicitly and define what can be lost:

<threshold value="ERROR" />

So i just need to use their inbuilt functions for inserting data to table. Now i need to retrieve data from the log table. Is log4net providing any functions for retrieving data from table? Or the only way to retrive data from this table is writing my own query? Anyone please help me.
I haven't tried it, but a simple Google search got me to http://code.google.com/p/log4net-db-viewer/ and some other results.
It does not look like there is any built in reader for any appender.
Log4net does not give you any tools to read your logs. Its only for making logs and it depends on the appenders to format and save the logs somewhere. There are many projects and samples which can read your logs depending on your appender:
read log4net logs
in this time I try to log into a DB whit L4N, this is the struct of the table:
[TcpClientTracer]
[ID] [int] IDENTITY(1,1) NOT NULL,
[Date] [datetime] NOT NULL,
[Thread] [varchar](20) NOT NULL,
[EventType] [varchar](20) NOT NULL,
[ClientId] [int] NOT NULL,
[ModemId] [varchar](128) NOT NULL,
[EventText] [varchar](2000) NOT NULL
to fill this table I use this appender:

the logger is this:
<logger name="TcpClientTracer" additivity="false">
<level value="ALL"/>
<appender-ref ref="TcpAdoNetAppender" />
</logger>
and...to pass the data from C# I use this method:
public static void writeLog(GroupType mGrupo, Hashtable mValues)
{
ILog Logger = oLogger.GetLoggerByGroup(mGrupo);
Type declaringType = typeof(log4net.LogManager);
LoggingEvent loggingEvent = new LoggingEvent(declaringType, Logger.Logger.Repository, Logger.Logger.Name, Level.All, null, null);//null = Message, Exception
foreach (DictionaryEntry CurrentEntry in mValues)
{
loggingEvent.Properties[CurrentEntry.Key.ToString()] = CurrentEntry.Value;
}
Logger.Logger.Log(loggingEvent);
}
I don't know how works the LoggingEvent, but I use it to fill other table and work perfectly.
If somebody can help me with this issue, I apreciate!!
Thanks to read my bad english!!
I am not 100% sure what you are asking. What I can tell you for sure is this: If you want to log custom properties, you need to use RawPropertyLayout and specify property name. Example:
<parameter>
<parameterName value="#clientid"/>
<dbType value="Int32"/>
<layout type="log4net.Layout.RawPropertyLayout">
<key value="clientid" />
</layout>
</parameter>
