Logging not logging

I've been attempting to set up Enterprise Library 4.1 logging within a console application. It simply contains the lines Logger.Write("Test") and Logger.Write("2nd test", "Category", 1, 1, TraceEventType.Error).

Executing it appears to do nothing, not even an exception is raised. Nothing is logged to the rolling flat file, event log, or e-mail which have all been configured. I've tried using the Quick Start from the included source code and this works! Does anyone have some ideas? Below is my config file:

I honestly have no idea as of the moment what's wrong with your config. Are you sure there aren't any enterprise library logs in the event log?   You said you tried it in the quickstart, meaning you used this config in place of the existing configuration included there?
If so, it should have thrown an exception because of mismatched assemblies.  Unless you changed the config in order to reference the unsigned ones?  Is this the case?

Hi Sarah,

I worked backwards from the Quick Start config and added in the configuration I needed. There are some subtle differences and no doubt one of those is why my config didn't work. Unfortunately I don't have the patience to work out which one of those it is.

In any case, thanks for your help!

Actually I do appear to have found a problem. It appears that if the Email TraceListener fails, then either:
  • logging for the other trace listeners in the same category source doesn't occur at all (with no error), or;
  • an exception shows in the event log describing the failure in the Email TraceListener and other trace listeners in the same category source do not log at all
The exception that displayed in the event log follows:

Timestamp: 03/04/2009 15:55:26
Message: Tracing to LogSource 'General' failed. Processing for other sources will continue. See summary information below for more information. Should this problem persist, stop the service and check the configuration file(s) for possible error(s) in the configuration of the categories and sinks.

Going back to your config, I tried it (Windows Server 2003), and your first log <Logger.Write("Test")> seem to have a success on the rolling flat file. However, I encounter before that i can't seem to log in a flat file because i dont have permission on a certain directory(That happenned when in a windows server 2008), so the workaround there is to grant permission to everyone on the directory where the log file is written. Your second log <Logger.Write("2nd test", "Category", 1, 1, TraceEventType.Error)> will not work, because you've specify a category named "Category" which does not exist your config.
On your last post, it seem that the specified mailing address to where your email trace listener will send the log is seems to be invalid or unavailable.try setting a valid mailing address to send to. Also configure your SMTP server if you need to.

Thank you, I appear to have this all working now.
