Dynamically add Souce and Category to EventLog
Hello There,
I am using the most recent version of Log4Net. I need to be able to add
source and category information on a per message basis. I am able to
successfully add this in the SQL server as I can utilize MDC properties.
Example:
MDC.Set("category", category);
Can I do something similar to EventLogAppender?
Thanks in advance.

The idea is to use the same Logger for multiple applications (Windows
Services, Web Services etc). For example System event log has sources like
DCOM, SCM, IIS etc. I would give extending EventLogAppender a try though.
Thanks.

There's this:
/// <summary>
/// Property used to set the Application name. This appears in the
/// event logs when logging.
/// </summary>
/// <value>
/// The string used to distinguish events from different sources.
/// </value>
/// <remarks>
/// Sets the event log source property.
/// </remarks>
public string ApplicationName
{
get { return m_applicationName; }
set { m_applicationName = value; }
}
Do you want the event source to be different for each log message? I
don't think that's a correct usage for the event source. If you need to
do that, I would extend EventLogAppender and override its Append
method. I would check for an ApplicationName as a property of the
loggingEvent or use the default value set in the config file if there
isn't one:
// untested...
string applicationName =
loggingEvent.LookupProperty("ApplicationName") as string;
if (applicationName == null || applicationName.Length == 0)
{
// use the default value
applicationName = ApplicationName;
}
// snip
EventLog.WriteEntry(applicationName, eventTxt, entryType, eventID);

Ron,
Thanks for your prompt replay. Although I have seen a lot of posts regarding
EventId, I still don't see anything related to setting the Source
dynamically. Can you please post me some code or redirect to a URL?
Regards,
Mohit
