Logging is not Tracing! Logging When you design a big application, you need to have good and flexible error reporting – perhaps across machines – to collect log data in a centralized way. That is a perfect use case for the Logging Application Block where you configure some remote trace listener, and send the log … Read more
The instructions should work exactly the same since the UI has not changed. Make sure that you install Failed Request Tracing, for that run OptionalFeatures.exe and make sure that Tracing is enabled in the Internet Information Services->World Wide Web Services->Health and Diagnostics.
Devel::Trace is the Perl analogue, the trace module is Python’s.
Take a look at Devel::Trace or Devel::ebug. Given this program named w.pl: #!/usr/bin/perl use strict; use warnings; my $answer = 42; if ($answer == 6 * 9) { print “everything is running fine.\n”; } else { warn “there must be a bug somewhere…\n”; } You can use Devel::Trace to watch the execution: perl -d:Trace w.pl … Read more
Logging is the generic term for recording information – tracing is the specific form of logging used to debug. In .NET the System.Diagnostics.Trace and System.Diagnostics.Debug objects allow simple logging to a number of “event listeners” that you can configure in app.config. You can also use TraceSwitches to configure and filter (between errors and info levels, … Read more

trace is the easiest to use method for debugging. It’s not in IO exactly for the reason you pointed: no need to lift your code in the IO monad. It’s implemented like this trace :: String -> a -> a trace string expr = unsafePerformIO $ do putTraceMsg string return expr So there is IO … Read more
Try specifying an assembly too, like so: <configuration> <system.diagnostics> <trace autoflush=”true” indentsize=”4″> <listeners> <add name=”TextListener” type=”MyApp.Utils.FormattedTextWriterTraceListener, MyApp” initializeData=”trace.log” /> <remove name=”Default” /> </listeners> </trace> </system.diagnostics> </configuration>
Assuming you only want to be notified for specific functions, you can do it like this: compile with debug informations (as you already have symbol informations, you probably also have enough debugs in) given #include <iostream> int fac(int n) { if(n == 0) return 1; return n * fac(n-1); } int main() { for(int i=0;i<4;i++) … Read more
In the very early days (.NET 1.0) tracing in the .NET Framework was pretty limited. For example TraceSource partitioning didn’t come until .NET 2.0 and you only had four levels (Error, Warning, Information, Verbose), although you could use half a dozen boolean switches for partitioning if you wanted. log4j is popular in Java and so … Read more
