Usage of the TraceSource object in asp.net

[Daniel Knöpfel]

Hi

We have to decided to use standard .net components for logging our asp.net
application (rather than log4.net or microsoft logging application blocks):
i tried to implement our logging using the TraceSource class. However, it
does not log anything. It works in a windows application but not in asp.net.

Am i doing something wrong or does the TraceSource class not work with
asp.net 2.0 ? This seems rather strange to me. At the bottom you find code
snippets from my web.config and my logging function:

Thanks for any help.

By the way, i do not seem to be the only one having this problem:

didnt get an answer)
<system.diagnostics>

<sources>

<source name ="Test">

<listeners>

<add name ="DelimitedListTraceListener" />

</listeners>

</source>

<source name ="Default">

<listeners>

<add name ="XmlWriterTraceListener" />

</listeners>

</source>

</sources>

<sharedListeners>

<add name="DelimitedListTraceListener"
type="System.Diagnostics.DelimitedListTraceListene r" delimiter=":"

initializeData="delimitedOutput.txt"

traceOutputOptions="ProcessId, DateTime" />

<add name="XmlWriterTraceListener"
type="System.Diagnostics.XmlWriterTraceListener"

initializeData="xmlOutput.xml"

traceOutputOptions="ProcessId, DateTime"

/>

</sharedListeners>

<switches>

<add name="Test" value="Verbose"/>

<add name="default" value="Verbose"/>

</switches>

</system.diagnostics>

Logging function:

public void Log(Exception pException, string pOriginStringOrKey,
TraceEventType pTraceEventType, bool pAddEnvironmentInformation)

{

try

{

if (pAddEnvironmentInformation)

{

IEnvironmentProvider provider =
EnvironmentProviderFactory.GetEnvironmentProvider( );

provider.AddEnvInformationToException(pException);

}

string messageString = GetMessageStringFromException(pException);

// log to specific tracesource

try

{

TraceSource traceSource = new TraceSource(pOriginStringOrKey);

traceSource.TraceEvent(pTraceEventType, 0, messageString);

traceSource.Flush();

}

catch

{

}

// log to default trace source

try

{

TraceSource defaultTraceSource = new TraceSource(DEFAULTRACESOURCE);

defaultTraceSource.TraceEvent(pTraceEventType, 0, messageString);

defaultTraceSource.Flush();

}

catch

{

}

}

catch

{

// ignore exceptions in log

}

}



I am trying to use the TraceSource object

Hi

It still does not work, so we resorted to use Log4Net, which works very
well.
