Re: How to make a part of log message uppercase

[Ron Grabowski]

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
