Sometimes we want to change the level of logging of a server in production.

I am not sure this is possible without restarting the server, which is often difficult to manage depending of the customer.

I know that log4j supports a way to dynamically reload the configuration when a file change has been detected. See configureAndWatch.

Is it supported in Ivy 4.x/5.x? Is there something we can do to enable this feature?

It is possible to change the log level of a Logger in an ivy project. E.g.


I have once started an ivy project that displays all current loggers in a tree and gives you the possibility to change threir level. I share this project here: LogViewer.iar

You can then deploy that project to the server and use it to change the log level of certain loggers.

Thank you Reto, we would be very interested in that LogViewer tool.

We were just talking last week about such a tool, that could be useful in production to change log levels.

Could you send me the sources? Because unfortunately, we don't have anymore access to your SVN repo from TI, due to technical problems about which Stéphane has already informed you recently.

ivy uses the API which does not watch for configuration changes: DOMConfigurator.html#configure(java.lang.String)

today I see no possability to change this behaviour without modifying the ivy core code in ch.ivyteam.log.Logger.

It could be a feature for a next release.

It is more difficult than using API DOMConfigurator.configureAndWatch(String), instead of DOMConfigurator.configure(String)?
