I'm trying to get Log4Net working with web email, either Yahoo or Gmail. If you have this working, I would appreciate some help, and thanks in advance.
I've got a default root logger, with a RollingFileAppender and an SmtpAppender. The file appender is working fine. The SmtpAppender is giving me nothing.
I am calling the logger from a diagnostic button click...
protected void btnReloadContractConfig_Click(object sender, EventArgs e)
{
// DIAGNOSTIC - Test email logger
log4net.ILog logger = log4net.LogManager.GetLogger("root");
logger.Error("btnReloadContractConfig_Click() - This is a TEST of delivery of error messages via email, triggered from the Admin.aspx.cs code file.");
}
...and the RollingFileAppender is getting the message...
LOC=20120921-12:03:16.319,UTC=20120921-11:03:16.319,DELTA=10078,THR=6,ERROR,LOG=root,[(null)] - btnReloadContractConfig_Click() - This is a TEST of delivery of error messages via email, triggered from the Admin.aspx.cs code file.
The web.config entries for Log4Net are here::
<appSettings>
<add key="log4net.Internal.Debug" value="true"/>

</appender>
</log4net>
The web.config is being picked up in the Global.asax file, in the Application_Start() handler...
void Application_Start(object sender, EventArgs e)
{
// Start Log4Net, signal app has started
log4net.Config.XmlConfigurator.Configure();
log4net.ILog logger = log4net.LogManager.GetLogger("root");
logger.Info("Application_Start()");
}
The admin web page that triggers the email attempt seems to either hang indefinitely, or hang momentarily (half second) and continue.
The dev environment does not collapse with an exception, it's either hang or glide on without error.
- How do I get additional diagnostics out of the SmtpAppender?
- Can I independently test the port/config to check for a local block on outgoing programmatic email?
- Is a log4net email guaranteed to be sent? The lossy and bufferSize properties seem very sensitive, if I put lossy=false, I get an indefinite hang...
For reference I am using VS 2010, ASP.Net4, and lots of caffeine. Thanks again for any forthcoming help.
