When I got a new logger it always had the level set to INFO but the documentation told otherwise (null), Hence I opened the code. The documentation and the code doesnt match. I am putting it on stackoverflow for others dont have to struggle /** * Protected method to construct a logger for a named subsystem. * <p> * The logger wil...
I have a small framework that is logging some info and debug messages using the Logger object built into ruby. At run time, this works great. At unit test time (using rspec if it matters...) i would like to dump the logged messages to an in memory string variable. What's the easiest way to go about doing this? I was considering a monkey...
Hello :) I have a logger class that handles various information display with pretty colors (yay.). However, since it writes to the console in separated steps (i.e. set color to red, write text, set color to gray, write text, for something that would render "[Error] Description..." with the error being in red), but I have a multithreaded...
What is the best (proper) way to share a logger instance amongst many ruby classes? Right now I just created the logger as a global $logger = Logger.new variable, but I have a feeling that there is a better way to do this without using a global var. If I have the following: module Foo class A class B class C ... class Z end ...
Due to the flooding examples of implementing logger using Singleton pattern, I just written a simple C++ logger in the same approach for my program. However, since the famous double-checked locking approach is known to be no more thread-safe, I wonder if I should: 1) Forget about the use of Singleton pattern in this case? 2) Continue t...

I would like to do this using java.util.logging if possible, any ideas? thanks. ...
i think it makes sense to use boost::singleton together with a boost::logger, so that all the objects in the executable can access the same logger and dump strings to it. class logger_singleton : public boost::mutexed_singleton<logger_singleton> { private boost::logger blogger; public: logger_singleton(boost::restricted);...
Someone might yell at me to read the faqqing faq, but I'm in a hurry ... Does anyone have a way to make javax or log4j logger refactor-sensitive? Say, that currently utils.Something has the logger handle: final static private Logger logger = Logger.getLogger(Something.class.getName()); And logging.properties has .level = warning ut...
Hi, I'd like to change dynamically the output used by the Logger. in the lib: @log = Logger.new(p, 10, 1024000) in the main class: mylib_instance.log.set_log(STDOUT) # something like that, but this does not work Mickael. ...
Hey, I'm trying to create a loggers hierarchy in my application. (I'm using standard java logger) To do so, I'm creating first the "grandfather" of all loggers by simply call: (In a static block) Logger.getLogger("myapplication"); Then, every concrete logger ask for logger: Logger.getLogger("myapplication.package1.Main"); and I c...
I want to create a logger class such that with a functionality like this: Logger log; log << "Error: " << value << "seen" << endl; This should print me a custom formatted message. E.g. "12-09-2009 11:22:33 Error 5 seen" My simple class currently looks like this: class Logger { private: ostringstream oss; public: ...

Hello, I am writing a c# logger to be used in a busy, multi-threaded application. I want to create 5 different loggers, where each of the loggers handles logging for different functionality. The loggers will be called by static as well as nonstatic code. Since the loggers write to a file, I want to synchronize the file access using l...
I have a class in which I see the following things: this.logger.severe(""); this.logger.warning(""); this.logger.info(""); I do not understand several things: How can we use a method that was not defined earlier? I mean, there are no "logger" methods defined in the class. I thought that these methods could be defined because the con...
I am using logback/slf4j to do my logging. I want to parse my log file to analyze some data, so instead of parsing a great big file (mostly consisting of debug statements) I want to have two logger instances which each log to a separate file; one for analytics and one for all purpose logging. Does anyone know if this is possible with Log...
The following simple code reproduces the growth of java.lang.ref.WeakReference objects in the heap: public static void main(String[] args) throws Exception { while (true) { java.util.logging.Logger.getAnonymousLogger(); Thread.sleep(1); } } Here is the output of jmap command within a few seconds interval: user@t1007:~> jmap -d64 -hi...
