This should work:
// untested
public class HostNameToUpperLayout : LayoutSkeleton
{
public override void ActivateOptions()
{
// empty
}
public override void Format(TextWriter writer, LoggingEvent loggingEvent)
{
string hostName =
(string)loggingEvent.LookupProperty("log4net:HostName");
writer.Write(hostName.ToUpper());
}
}
<parameter>
<parameterName value="@message"/>
<dbType value="String"/>
<size value="4000"/>
<layout type="Company.Application.HostNameToUpperLayout,
Company.Application" />
</parameter>
There are more clever ways of doing it but that should work.

Subject: How to make a part of log message uppercase
Hello,
I'm using AdoNetAppender to log messages. I've added
%property{log4net:HostName} conversion pattern to the message parameter.
<parameter>
<parameterName value="@message"/>
<dbType value="String"/>
<size value="4000"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="[%property{log4net:HostName}] - %message"/>
</layout>
</parameter>
Output is like
[hostname] - foo bar.
But i want the output like
[HOSTNAME] - foo bar.
How can i make the hostname uppercase using conversion patterns?
Regards,
Cankut
