Logging using Log4Net

[ozgurnevres <oz...@gmail.com>]

Hi,

I want to use log4net for logging. Ignite starts from
ApplicationConfiguration like this:
Ignition.StartFromApplicationConfiguration()

It seems it isn't logging in C:\Logs. What am I doing wrong? Ignite
configuration is like 

  <igniteConfiguration
xmlns="http://ignite.apache.org/schema/dotnet/IgniteConfigurationSection"
gridName="myGrid1" clientMode="false" jvmMaxMemoryMb="6144">
    <logger type="Apache.Ignite.Log4Net.IgniteLog4NetLogger,
Apache.Ignite.Log4Net" />
...

And Log4Net configuration in app.config:
  <log4net>
    <appender name="RollingLogFileAppender"
type="log4net.Appender.RollingFileAppender">
      
      
      
      
      
      
      
      
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger
[%property{LogName}] - %message%newline" />
      </layout>
    </appender>
    <logger name="ProductionLogger">
      <appender-ref ref="RollingLogFileAppender" />
      
      <level value="ALL" />
    </logger>
  </log4net>

Hi,

Hm, actually, you've got several log4net misconfigurations in your solution.
Everything was fine with Ignite config itself ).
Please see updated minified solution attached. Just "build a solution" and
it will restore all required packages.

The following log4net misconfigurations fixed:

1. Your app.config file section <log4net> was ignored, an explicit call
XmlConfigurator.Configure() is required for log4net.

2. you should always have <root> logger in <log4net> section.

3. <logger> name attribute could not be abstract. It should have some
package name.

4. %property{LogName} from xml should be initialized in global context
before usage. Please see call 
log4net.GlobalContext.Properties["LogName"] =
System.Reflection.Assembly.GetExecutingAssembly().GetName().Name;

Please find more info about log4net at [1]

Thank you,
Alexey

"please ensure that your log4net configuration section <log4net> is 
actually used"

How can I ensure that? It seems there's no property in logger configuration
to tell which appender will be used.

Hi,

There could be several issues. Unfortunately, you just provided some config
snippets.

First of all, please add <file value="somename.log" /> to your appender
RollingLogFileAppender config.

Then, please ensure that your log4net configuration section <log4net> is
actually used.
It is better to have a separate file log4net.config file.

Please share a simple reproducer project if you still face any issue.

Thank you,
Alexey
