[Bug 257] Recommended Logger Name

09 May '12

http://bugzilla.slf4j.org/show_bug.cgi?id=257 --- Comment #4 from Joachim Durchholz <jo(a)durchholz.org> 2012-05-09 22:19:28 CEST --- While an aircraft carrier is quite different from a motorboat, you still don't use aluminium for the wiring. Argument by analogy doesn't fly, you always need to justify why your analogy holds and why the other doesn't - IOW you need to argue substance anyway and the analogy doesn't help a bit. Why using logger names is a bad idea: - You say you need to identify the product in the log message. Then you say you need to identify the business entity. You're trying to stuff quite a lot of very different things into the same name here. Plus, there's always a lot of code that doesn't quite fit the classification of "product" or "business entity". - Logger names are hierarchical for a reason: they eliminate the need to reconfigure logging for different modules, you can factor out configuration from submodules into supermodules. You lose that if you switch to a flat "product" namespace. - Identifying the business entity often isn't enough, you also need the ID (customer ID etc.). You can't put dynamic data into the logger name, so that use case isn't covered by your approach. - Any third-party software that you use will have hardcoded classnames in its loggers. You'll get a hodgepodge of class names and product names in your logs. Why not put product/whatever names into the log message text? You can always create your own logging framework. A thin layer above Logger that has warn(String moduleName, String message, Object... params) that does warn(moduleName + ": " + message, params). (There are ways to optimize that.) BTW I *have* scoured log messages. Knowing the class name is helpful. I'm also seeing people blog about moving from non-classname logger names back to classname-based ones, but not the other way round. Have mercy on your developers. There are better ways to achieve what you want.

http://bugzilla.slf4j.org/show_bug.cgi?id=257 --- Comment #2 from Irv Rabin <ipr1118(a)gmail.com> 2012-05-09 20:47:43 CEST --- Thanks Joachim, I expected a response like that. :) Well, logging is not only "to collect information to help developers fix the problem". That is debugging. Only logging messages with level DEBUG fit into your definition. Well, perhaps TRACE to a certain degree. Logging is to collect data about a running process so the latter can be analyzed later. For example, a big commercial billing application may want to have a log where the whole billing process can be traced and reconstructed. The application may have thousand of classes. Messages relevant to one billing cycle that logically belong to the same logger could be produced by any of the classes comprising the application. The logger could be defined for a whole subsystem (such as Billing). Then, as the application can be divided into subcomponents, the logging could be distributed into subloggers (Billing.Notification, Billing.Payment, etc), so the dots would still show hierarchy and configuration with inheritance of settings could be honored. But whenever the system is composed of tens of thousands of classes, using class names as logger name is simply insane. Like a motorboat driver has a very vague idea how to drive an aircraft carrier ship, in the same way recommendations that are sound for small Proof-Of-Concept projects, are inapplicable to big commercial applications. That's why I believe that recommendation of using class names as logger names should be limited to small pilot projects, where the developer is the primary user of his own code. -- Configure bugmail: http://bugzilla.slf4j.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

Logging is for collecting internal information that helps developers fix problems. Class names are just right for that purpose. Also, the logger name is used to identify logging configuration, e.g. what severity of logging levels to use for what parts of the logger namespace. You'll always have dots in the logger names (or you'll have to configure every single logger in the system manually). Third, you can't change the logger names of third-party software you're using. You should include the business entity in the log message. (That's something I do as a matter of course.) -- Configure bugmail: http://bugzilla.slf4j.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

Add a logging.properties to jul-to-slf4j?
by Robert Elliot 08 May '12

08 May '12

Hi all, Whenever I create an app where I want to redirect java.util.logging to SLF4J I have to remember to do two things - add jul-to-slf4j to the class path and add a logging.properties file with the following format: handlers = org.slf4j.bridge.SLF4JBridgeHandler to the class path. It suddenly occurred to me that it might be simpler just to have that logging.properties file in jul-to-slf4j. Then it would be job done in one go. Presumably if you;re including jul-to-slf4j on the class path then you don't want to configure any other logging… Any thoughts? Rob
