I want to have log messages from each log level go to a different file. From the name, LevelMatchFilter seems like what I want, except it seems to not filter anything from a different level.
I think the following properties should do that using LevelRangeFilter. However, anything sent to the global logger ends up in INFO.log, regardless of the level.
log4j.rootLogger = OFF
# Global level based logs
log4j.logger.global = ALL, Info
log4j.appender.Info=org.apache.log4j.FileAppender
log4j.appender.Info.File=Logs/INFO.log
log4j.appender.Info.layout=org.apache.log4j.PatternLayout
log4j.appender.Info.layout.ConversionPattern=%d [%p] %m%n
log4j.appender.Info.filter.a=org.apache.log4j.filter.LevelRangeFilter
log4j.appender.Info.filter.a.LevelMin=info
log4j.appender.Info.filter.a.LevelMax=info
log4j.appender.Info.filter.a.AcceptOnMatch=true
I also tried using INFO for the values of LevelMin and LevelMax but that had the same results.
What am I doing wrong?
As a side question, is there a way to turn on debugging of the log4cxx configuration when using a property file? I found an option when using an xml file, but none of the obvious translations to properties (debug=true, log4j.debug=true) and any effect.
As of log4cxx 0.10 (and probably earlier), the properties format does not support filters. So the XML configuration (or programmatic configuration) is required.
<?xml version="1.0" encoding="UTF-8" ?>
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="true">
<appender name="Info" class="org.apache.log4j.FileAppender">
<param name="file" value="Logs/INFO.log" />
<param name="append" value="false" />
<!-- If this filter accepts the message, it will be printed. That happens if this is an info message -->
<filter class="org.apache.log4j.filter.LevelMatchFilter">
<param name="levelToMatch" value="INFO" />
<param name="acceptOnMatch" value="true" />
</filter>
<!-- If it is not an info message, this filter will reject it -->
<filter class="org.apache.log4j.filter.DenyAllFilter"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d [%p] %m%n" />

I use log4net and log4net.Async in my application to logs.It works good on my local environment(VS2017).When i release it and publish it to the IIS server,it works well at the starte time.But after i recycle the service,it can't write logs anymore,the log file is still there but has no log message inside.
I set the log folder whith permission(READ\WIRTE) for EVERYONE already.
there is my log config:
<appender name="InfoRollingFileAppender" type="log4net.Appender.RollingFileAppender">
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<param name="Encoding" value="utf-8" />
<param name="File" value="D:\Log\Info\" />
<param name="AppendToFile" value="true" />
<param name="rollingStyle" value="Date" />
<param name="datePattern" value="yyyyMMdd\\yyyy-MM-dd-HH.'Info.log'" />
<param name="staticLogFileName" value="false" />
<layout type="AsPay.GateWay.Log.AsRefundAccLayout">
<conversionPattern value="--logtime：%date --：%-5level--msg：%Logtxt --：%CallType%newline" />
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<param name="LevelMin" value="INFO" />
<param name="LevelMax" value="INFO" />
</filter>
</appender>
<appender name="asyncForwarder" type="Log4Net.Async.AsyncForwardingAppender,Log4Net.Async">
<appender-ref ref="InfoRollingFileAppender" />
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="asyncForwarder" />
</root>
code in Global.asax:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
System.IO.FileInfo fileinfo = new System.IO.FileInfo(Server.MapPath("~/log4net.Config"));
log4net.Config.XmlConfigurator.Configure(fileinfo);
}
The strange thing is after recycle the IIS,the log file(eg:2019-04-10-00.Info.log) is continued to be created,but there is no log content in the logfile.After recycle the IIS, There are no problems with the functionality of the service,except the log.
I have an application that uses log4cxx internally, with dozens of loggers. What is a minimal logger.properties that I can setup to turn off all logging output?
In particular I'm getting a warning like (no properties file present):
log4cxx: No appender could be found for logger (FileSource).
log4cxx: Please initialize the log4cxx system properly.
FileSource is a class that uses log4cxx.
My goal is to preclude all log4cxx output at runtime.
This should do it:
<?xml version="1.0" encoding="UTF-8" ?>
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<root>
<priority value="OFF" />
</root>
</log4j:configuration>
A simple logger.properties that logs to standard out could look like below:
<?xml version="1.0" encoding="UTF-8" ?>
<!-- add attribute debug="true" to log4j:configuration tag to see how logger reads it's configuration. -->
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="ConsoleAppender" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %-5p %c (%F:%M:%L) - %m%n" />
</layout>
</appender>
<root>
<priority value="DEBUG" />
<appender-ref ref="ConsoleAppender"/>
</root>
</log4j:configuration>
Im using Unity (3.0) interception to add some crosscutting concerns to my application. Somehow I can't use the MethodSignatureMatchingRule in my configuration getting this error message:
{"The type name or alias MethodSignatureMatchingRule could not be resolved. Please check your configuration file and verify this type name."}
My configuration:
<?xml version="1.0"?>
<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
<sectionExtension type="Microsoft.Practices.Unity.InterceptionExtension.Configuration.InterceptionConfigurationExtension, Microsoft.Practices.Unity.Interception.Configuration" />

<interception>
<policy name="EhabAspect">
<matchingRule name="MethodSignatureMatchingRule" type="MethodSignatureMatchingRule">

</constructor>
</matchingRule>
<callHandler ... (omitted)

<register type="IMyClass" mapTo="MyClass">
<lifetime type="singleton" />
<interceptor type="InterfaceInterceptor"/>
<policyInjection/>
</register>
</container>
</containers>
</unity>
The same configuration with the NamespaceMatchingRule works fine.
My assembly contains a reference to
Microsoft.Practices.EnterpriseLibrary.Common
Microsoft.Practices.Unity
Microsoft.Practices.Unity.Configuration
Any suggestions?
I was facing the same problem here. I solved using the full qualified name of the of the class.
<matchingRule name="AuthorizationMethod" type="Microsoft.Practices.Unity.InterceptionExtension.MethodSignatureMatchingRule, Microsoft.Practices.Unity.Interception">
<constructor>
<param name="methodName" value="Authenticate" type="string"/>
<param name="parameterTypeNames" dependencyName="EmptyArray"/>
</constructor>
</matchingRule>
I am using SlowCheetah to transform my Log4Net files when I publish. However, it can't seem to distinguish between the attributes in different appender sections.
My Log4Net.config looks basically like this:
<?xml version="1.0" encoding="utf-8" ?>
<log4net>
<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
<to value="DevEmail" />
<from value="DevEmail" />
<subject value="Dev Warning" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="Time: %date%newlineHost: %property{log4net:HostName}%newlineClass: %logger%newlineUser: %property{user}%newlineMessage: %message%newline%newline%newline" />
</layout>
<threshold value="WARN" />
</appender>
<appender name="FatalSmtpAppender" type="log4net.Appender.SmtpAppender">
<to value="DevEmail" />
<from value="DevEmail" />
<subject value="Dev Fatal" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="Time: %date%newlineHost: %property{log4net:HostName}%newlineClass: %logger%newlineUser: %property{user}%newlineMessage: %message%newline%newline%newline" />
</layout>
<threshold value="FATAL" />
</appender>
</log4net>
And my transform file looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<log4net xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
<to value="ProductionEmail" xdt:Transform="SetAttributes" />
<from value="ProductionEmail" xdt:Transform="SetAttributes" />
<subject value="Production Warning" xdt:Transform="SetAttributes" />
</appender>
<appender name="FatalSmtpAppender" type="log4net.Appender.SmtpAppender">
<to value="ProductionEmail" xdt:Transform="SetAttributes" />
<from value="ProductionEmail" xdt:Transform="SetAttributes" />
<subject value="Production Fatal" xdt:Transform="SetAttributes" />
</appender>
</log4net>
The problem is that the transformed config has the same subject attribute value for both appenders; I guess when it hits the SetAttributes it can't tell which tag it's looking for, so it transforms all of them. What it the correct syntax to tell it to only find the elements within the same appender? I assume I need to use the xdt:Locator attribute, but I can't do Match(name) like I do for web.config because these elements don't have a name attribute. The appender element has a name attribute, but I don't know how to tell it to match based on the parent element's name.
I know that I could use replace on the appender node, with the match(Name), but then I would be replacing the entire node, including a bunch of elements such as the layout which I don't want to be transformed (and thus have multiple copy-pastes of the same code, which I would like to avoid).
I found the answer in this MSDN article: http://msdn.microsoft.com/en-us/library/dd465326.aspx.
I needed to use xdt:Locator="Match(name)" on the parent <appender> node, and then xdt:Transform on the child nodes. I had tried this previously but had used xdt:locator="Match(name)" instead of xdt:Locator="Match(name)"... The attribute is case sensitive.
really simple question -> i can't seem to get any data from Log4Net in my ASP.NET application. I've got a simple ASP.NET website, which references a class library. In this class library, I have some lines that call the logger.
I'm trying to read the log4net output data in my Visual Studio 2008 debugging Output window.
Here's my code and my configuration...
//Class Library project
//File: Foo.cs
public class FooService
{
private static readonly ILog log = LogManager.GetLogger(typeof(FooService));
public FooService()
{
// NOTE: To play with my L4N settings, I'll call Debug once, then Info once.
log.Info("Starting Constructor");
// ... snip ...
log.Debug("Leaving Constructor");
}
}
// ASP.NET Website project
// File: global.asax
void Application_Start(object sender, EventArgs eventArgs)
{
log4net.Config.XmlConfigurator.Configure();
}
// File: Whatever.aspx.cs
// A delegate method (when a user clicks a button) creates the FooService() instance.
// File: web.config
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler" requirePermission="false" />
// ....
</configSections>

</logger>
</log4net>
Cheers for any help or suggestions...
EDIT: Added the RollingLogFileAppender.
I had this same problem and I think it was looking at the wrong web.config or something. I finally separated out log4net.config from web.config and put a path to it \inetpub\Logs\log4net.config and all is well.
UDPATED ON REQUEST: edited from a slightly more complicated version.
<?xml version="1.0" encoding="utf-8"?>
<log4net>
<appender name="TraceAppender" type="log4net.Appender.TraceAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level (%logger:%line) - %message%newline" />
</layout>
</appender>\
<root>
<!--ALL, DEBUG, INFO, WARN, ERROR, FATAL, OFF-->
<level value="ALL" />
<appender-ref ref="TraceAppender" />
</root>
</log4net>
And it is configured in code as follows:
var logpath = WebConfigurationManager.AppSettings["LogConfigPath"] ?? #"\Inetpub\Logs\log4net.config";
var finfo = new System.IO.FileInfo ( logpath );
XmlConfigurator.Configure( finfo );
ASP.Net has restriction on usage of filesystem access, so try to explicitly point directory under App_Data (were it is allowed)
Here my working sample:
<log4net>
<appender name="FileAppender" type="log4net.Appender.FileAppender">
<file value="App_Data\logging\log-file.txt"/>
Or with rollover
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="App_Data\logging\log-append.txt"/>
Ok, found the answer. I needed to use a TraceAppender.
The application configuration file
can be used to control what listeners
are actually used. See the MSDN
documentation for the Trace class for
details on configuring the trace
system.
Events are written using the
System.Diagnostics.Trace.Write(string,string)
method. The event's logger name is
passed as the value for the category
name to the Write method.
Here's my config file data...
<log4net>
<appender name="TraceAppender" type="log4net.Appender.TraceAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
<!-- Setup the root category, add the appenders and set the default level -->
<root>
<level value="ALL" />
<appender-ref ref="TraceAppender" />
</root>
</log4net>
There are atleast 2 possible problems:
The way the address to the file is specified, try using an absolute path instead.
The process making the call needs rights to modify the file. Check that the user account making writing to the log file has rights to do so.
To debug it I would create and empty directory, give everyone full control, configure to log to that directory. Then test it, see that it works, then gradually tighten the security to an acceptable level.
I added the following line Global.asax file, and it works..!!
log4net.Config.XmlConfigurator.Configure();
