Live logging with log4net and WCF part 2

Posted on One min read

In previous post I showed how to create a publish/subscribe logger with WCF and log4net, now I show you my first use of this particular appender.

When you work with nhibernate you can use show-sql configuration parameter to instruct nhibernate to show generated sql, but how can you see this output in a running windows application? You should know that NHibernate has various log4Net logger, and you can instruct the session to dump all sql code to a logger, here it is a possible configuration

<appender name="WCFAppender" type="LiveLogger4Log4Net.WCFAppender, LiveLogger4Log4Net">
    <layout type="log4net.Layout.PatternLayout" >
        <conversionPattern value="%date [%thread] %-5level %logger %ndc - %message%newline" />
    </layout>
</appender>

<logger name="NHibernate.SQL" additivity="false">
    <level value="DEBUG" />
    <appender-ref ref="WCFAppender" />
</logger>

With this configuration I instruct NHibernate to log to WCFAppender all generated SQL. Now I can attach a log viewer to a running application and look in real time to the sql instruction that nhibernate generates. You can attach more than one application, whenever you want.
