I'm writing messages to the Linux syslog using Log4j and its SyslogAppender. The outputted messages look like this: Oct 12 09:06:03 localhost.localdomain 3364 [Thread-5] INFO TEST MESSAGE MyApplicationLogger - This is my message I would like to replace localhost.localdomain with the name of the server running the application but can't seem to figure out how. Here's my configuration file, in case it's useful: log4j.logger.MyApplicationLogger=INFO, SyslogAppender log4j.appender.SyslogAppender=org.apache.log4j.net.SyslogAppender log4j.appender.SyslogAppender.syslogHost=localhost log4j.appender

How can i log every method called in a class automatically with log4j

半腔热情 提交于 2019-12-03 09:22:48
问题 I have a class with database calls, and I generally want to log every method called (with arguments) in this class with log4j: logger.debug("foo(id="+id+") initiated"); Is it possible to do this automatically? Maybe by using some sort of annotation in start of each method instead of writing every single logger.debug? Today I have to update my logging.debug every time I change arguments or method name. 回答1: Try @Loggable annotation and an AspectJ aspect from jcabi-aspects (I'm a developer):

Grails Log4J Not Logging In Production

本小妞迷上赌 提交于 2019-12-03 09:08:00
I have a Grails 1.3.7 application and am trying to setup log4j for production in the configuration. The log4j settings were fine in development, but I can't get anything to show for production. I am trying to make a rolling file among other things, but I can't get anything to show. I even have the configuration at the "info" level so that I can ensure something will come through. I don't see anything of interest in the tomcat logs on the server. Any ideas? log4j = { def catalinaBase = System.properties.getProperty('catalina.base') if (!catalinaBase) catalinaBase = '.' // just in case def

Logback reliability

It is a best-effort fail-stop logging system." Is Logback more reliable? Is it possible that when 1000 log messages (for example) are written using logback in a very short span of time, it might silently miss a few messages. Thanks, Sunil 回答1: I think that Logback is also a best-effort fail-stop logging system. Run this snippet: for (int i = 0; i < 8; i++) { System.out.println("log " + i); logger.info("log {}", i);

I am on OS X. Could this be done using a conversion pattern to output some control codes or would it need a custom appender?
