filtering on message source

["Dalton, Barnaby" <Ba...@brevanhoward.com>]

I need to combine messages from one class with messages of level WARN or
above from other classes. I can easily log the WARN and above messages
but was wondering on the best way to add in ALL messages from the
specific class. Is the best technique to define a second logger and then
use LoggerMatchFilter in the appender? Can I avoid having to define a
second logger and use some kind of ClassSource filter?

Thanks

Here's how to use it:

 <filter type="Company.Project.Logging.CustomFilter">
  <logLevelEqualOrAbove value="WARN" />
  <allMessagesFromLogger value="Company.Project.UI.Login" />
  <allMessagesFromLogger value="Company.Project.UI.Logout" />
 </filter>
 <filter type="log4net.Filter.DenyAllFilter" />

public class CustomFilter : FilterSkeleton
{
 private Level logLevelEqualOrAbove = Level.All;
 private Hashtable acceptAllMessagesLookup = new Hashtable();

 public override FilterDecision Decide(LoggingEvent loggingEvent)
 {
  if (acceptAllMessagesLookup.Contains(loggingEvent.LoggerName))
  {
   return FilterDecision.Accept;
  }
  else
  {
   if (Level.Compare(loggingEvent.Level,LogLevelEqualOrAbove)>=0)
   {
    return FilterDecision.Accept;
   }
   else
   {
    return FilterDecision.Deny;
   }
  }
 }

 public Level LogLevelEqualOrAbove
 {
  get { return logLevelEqualOrAbove; }
  set { logLevelEqualOrAbove = value; }
 }

 public void AddAllMessagesFromLogger(string logger)
 {
  acceptAllMessagesLookup[logger] = null;
 }
}

Re: filtering on message source

It sounds like you need to write a custom filter that looks like this:

 <filter type="Company.Project.Logging.CustomFilter">
  <logLevelEqualOrAbove level="WARN" />
  <allMessagesFromLogger name="Company.Project.UI.Login" />
  <allMessagesFromLogger name="Company.Project.UI.Logout" />
 </filter>

That would accept all messages from Login and Logout and only those
messages from other loggers that are WARN or above.

Is that correct?
