Category is missing

Hi, my log4j2.xml specifies a pattern (%d{HH:mm:ss.SSS} %-5level [%t] %c - %msg%n), which ought to include the category. However, my log file looks like below. Am I missing something obvious here? Thanks, Jochen 2017-08-14 16:38:09,700 localhost-startStop-1 DEBUG PluginManager 'Core' found 112

Different Processes, same Logfile

Hi, is it possible. that multiple proceses share a common log file. (The processes aree command line executables, ,which will be started at unpredictable times. Thanks, Jochen -- The next time you hear: "Don't reinvent the wheel!" http://www.keystonedevelopment.co.uk/wp-content/uploads/2014/

Multiple instances of log4j2.xml

Hi, I have an application (more precisely: a war file), which is deployed identically on the same application server. (Think multi temancy), Now, in Log4j 1, I handled that situation quite easily, like this: final String uri = tenantName + "/log4j.xml"; final URL url = ClassLoader.getReso

Dynamically creating loggers

Hi, I've got an application, where I would like to obtain loggers on the fly, because the logger name isn't known in advance. (Think of it as a logging server, which will be used by remote clients.) Now, creating a Logger might be an expensive operation. Thus, my question: - Would you recommend

Re: LoggerContext is reloaded on application shutdown

This is quite as it should. If the webapp is being shutdown, then all acquired resources (including the logging system) are to be released. You'd end up with a resource leak otherwise. Why do you expect log4j to be an exception? Jochen On Tue, Oct 20, 2015 at 6:41 PM, Benoit Mouquet wrote: > He

My understanding is that generating this information doesn't add to the performance penalty of creating a stack trace, so I don't think its worth bothering. On Tue, Jun 30, 2015 at 1:09 AM, Gary Gregory wrote: > Worth a FAQ or manual entry? > > Gary > > On Mon, Jun 29, 2015 at 9:33 AM, Ralph Goe

What happened to chainsaw?

Hi, following the instructions on http://logging.apache.org/log4j/docs/chainsaw.html I downloaded install-chainsaw.xml, which seems to do its job. However, the downloaded build.xml neither contains a "chainsaw" target nor does the "chainsaw" directory contain any relevant files. Thanks, Jo

Chainsaws file format

Hi, sorry if I am missing something obvious, but my impression is, that chainsaw can parse only files in the pseudo xml format. I would need to parse files generated using the pattern layout. Is it possible to achieve that? Regards, Jochen -- Having experienced 7 years of labour/green governme
