log4j

问题 I am trying to figure out how to simply rename the active log file on every startup, and archive all the rotated files once a week. I am forced to specify the "filePattern" at the RollingFile appender declaration, instead of at the policy. Do this make sense? 回答1: I ended up doing my own implementation of a DeleteAction, and attaching it to a DefaultRolloverStrategy, so that it is zipping everything before deleting.

问题 From this answer https://stackoverflow.com/a/25125159/4367326 I have routingAppender working but I want to set the ThreadContext for every thread in the program. When I set ThreadContext.put("logFileName", "TestLogFile"); it works for the main thread and logs as expected but not for any other threads in my application.

问题 I have a log file (log4j xml-ish format) that I am trying to pull info out of and use in my Python module. Could I treat this file as if it were XML? My gut is telling me no... If not, what is the best way to parse the data? Below is a section of the log file. The file does not include your standard doctype or version headers which is why I said "xml-ish." <log4j:event logger="com.hp.cp.elk.impl.subscriptions.AsyncSimpleSubscriptionManager" timestamp="1352320517430" level="DEBUG" thread=

问题 Situation: We use SLF4j and Log4j 2 with asynchronous appenders Problem is we also use JSF which uses java.util.Logging .

问题 I am able to create log files using FileAppender, RollingFileAppender,etc., My Problem is that the logs are written as plain text that anyone can read, but I want to register my logs as Binary Files that are not human readable. Can anyone help me with the suggestion to create a Binary log file for an example code. 回答1: Its not such a good Idea to do what you wrote, but if you really need to, write an own appender like this: package de.steamnet.loggingUtils; import java.io

问题 I need to configure DST time for some application running in a server which is in Fiji. OS level time has configured properly : Tue Nov 11 17:28:51 **FJST** 2014 (FJST - Fiji Summer Time) I have changed the log4j.xml configuration as follow and tried: <layout class="org.apache.log4j.EnhancedPatternLayout"> <param name="ConversionPattern" value="%d{ISO8601}{GMT+13} %-5p %c{1} [%x] [%t] - %m%n" /> This works bit fine, but this can be a workaround only, can't be a solution.
