I think you are on the right track with the filter idea. You will need
to write a custom filter to look at the value of your userID parameter.
It could look something like this:
public class UserParamFilter : log4net.Filter.FilterSkeleton
{
private long m_userID;
public long UserID
{
get { return m_userID; }
set { m_userID = value; }
}
public override log4net.Filter.FilterDecision
Decide(log4net.Core.LoggingEvent loggingEvent)
{
object val = loggingEvent.LookupProperty("UserID");
if (val != null && val is long)
{
if (m_userID == (long)val)
{
return log4net.Filter.FilterDecision.Accept;
}
}
return log4net.Filter.FilterDecision.Neutral;
}
}
You may want to get your allowed users IDs from somewhere or you may
need to pass in a list etc. You could do this by writing an
AddUserID(long userId) method which built up a list.
You can then configure your appender with a threshold and filter chain
something like this:
<appender name="ConsoleAppender_Filter3"
type="log4net.Appender.ConsoleAppender" >
<layout type="log4net.Layout.PatternLayout" value="%date %-5level
%logger - %message%n" />
<!-- Reject anything below DEBUG -->
<threshold value="DEBUG" />
<!-- Accept anything of INFO or above -->
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="INFO" />
<levelMax value="OFF" />
</filter>
<!-- Update the type value to the assembly qualified name of your
filter -->
<filter type="TestConsoleApp.UserParamFilter, TestConsoleApp">
<userId value="123" />
</filter>
<!-- Deny events that do not match any of the above filters -->
<filter type="log4net.Filter.DenyAllFilter" />
</appender>
