How to Change Log4Net Rolling file appender to smtp appender or ADODB appender
Hi All,
Currently log4net publisher logs the data in a file according to the configuration done in Runtimeconfig.xml > log4net publisher > innerXML.
I want the log4net to publish into different appenders such as SMTP or ADO.NET and other things. I tried changing the inerXML to appropriate appenders ( as given in the url :https://logging.apache.org/log4net/release/config-examples.html by appropriate encoding) and getting the below error. Does any one have idea how to use it or open span does not support it ?

Note : i am able to achieve it using script method and the appender of my choice, but i want to achieve using the built-in log4net publisher and avoid C# scripting.

It looks like all of the Log4Net logging is based on using a control that is based on a log4net.Appender.FileAppender. The SmtpAppender for instance is based on the BufferingAppenderSkeleton.

The Log4Net publisher was added a few years ago so that clients could have full time logging in production if they desired without the worry of filling the hard drive. Since you can roll logs and limit the size it is safer. We had some clients whose users would only restart their machines weekly or longer and that resulted in some very large RuntimeLog files.
