logging

问题 I have developed a C++ based COM object to use it in a VB6 application. Now I need to add some logging to catch some of the bugs. I discovered from the answer to 'How to debug COM object in Visual Studio 6.0' question that I can use the OutputDebugString function. But is it possible to write to the VB6 immediate window somehow? 回答1: Rather than attempting to write to the immediate window, it would be generally more useful to use DebugView from Sysinternals (now part of Microsoft technet):

问题 I need to know what is exactly the REST message body before sending it to client and also its response before processing, so I try to use Interceptors but unfortunately it is NOT working. @NameBinding public @interface DoIt {} @DoIt public class MyFilter implements ContainerRequestFilter {...} @Path("/root") public class MyResource { @GET @DoIt public String get() {...} } I can not use wireshark to capture http messages because my server only accept Https requests. I searched a lot and find

问题 Tomcat logges in eclipse everything starting with DEBUG. It doesn't log only its own properties but other stuff allow themselves to log (like: [localhost-startStop-1] DEBUG o.s.w.c.s.StandardServletEnvironment or [localhost-startStop-1] DEBUG o.s.c.i.s.PathMatchingResourcePatternResolver and many many others). I want to limit tomcat logging to info or warning. I tried going into the tomcat directory and changing the log level in logging.propertie from "FINE" to "INFO" to no avail. I even

问题 I'm just a bit confused with the parameters in a pointcut would appreciate if anyone could explain it to me... import Java.util.logging.*; import org.aspect j.lang.*; public aspect TraceAspect { private Logger _logger = Logger.getLogger("trace"); TraceAspectV2() { _logger.setLevel(Level.ALL); } pointcut traceMethods() (execution(* Account.*(..)) || execution(*.new(..))) && !within(TraceAspect); before () : traceMethods() { if (_logger.isLoggable(Level.INFO)) { Signature sig =

问题 Although in some tutorials, for example here ( Parametrized logging section), said that Logback message {} parametrization help us to avoid unnecessary calculation in logging data (if logging level is not DEBUG): logger.debug("The bonus for employee {} is {}", employee.getName(), employeeService.calculateBonus(employee)); I tested (on logback version 1.2.3 ) that this optimization works only for unnecessary toString() of parameter object - as this works for log4j . Logback documentation doesn

问题 i aked myself if it is possible in MS SQL-Server 2005 to get information of a running stored procedure. Because meanwhile it is executing for more than 8 hours, i would like to know on what step it is or if it is even actually running at all. MS SSMS says that it is still executing the query.

问题 i know there are tons of posts about sub-stringing, believe me i have searched through many of them looking for an answer to this. i have many strings, lines from a log, and i am trying to categorize and parse them. they look something like this: /long/file/name/with.dots.and.extension:Jan 01 12:00:00 TYPE Static Message;Dynamic Message where the filename is the file where the log is located, the date is the date/time that the message was put into the log, and the TYPE is the type of message,

问题 I am trying to migrate from Log4j 1.7 to Log4j2.4 In 1.7, I as creating AppLogger class by extending org.apache.log4j.Logger and using extending debug/error/fatal Methods e.g., public void error(Object message) { Object error = message; if (message instanceof Exception) { Exception e = (Exception) message; StringWriter sw = new StringWriter(); e.printStackTrace(new PrintWriter(sw)); error = sw.toString(); } super.error(error); } But in Log4j 2.x, I am not able to extend the class org.apache

问题 Is there a way to group logs of a python web application which belong to one web request? Example: 2015-02-11 13:06:32 myapp.middleware.MYAPPMiddleware: INFO Login of user foo was successful 2015-02-11 13:06:32 myapp.middleware.MYAPPMiddleware: INFO Login of user bar failed 2015-02-11 13:06:32 myapp.send_mails: INFO failed to send mail to someone@example.com The above log lines are unrelated to each other. How can you solve this the pythonic way? 回答1: Log entries in their essence are designed

问题 I once found a way to disable session logging by php -a , php's interactive shell. How do I turn it back on? Is there a way to send logging to another, file besides ~/.php_history ? I think I may have sent the output to /dev/null . edit: It apparently still saves to the .php_history file. It doesn't save until you exit completely from the shell. I would still like to know how move the history logging to another file. 回答1: No, currently (5.3.10 ubuntu) the filename ~/.php_history is hardcoded
