问题 Log4j2 also uses shutdown hooks to end it's services. But of course I want to log throughout the whole lifecycle of my application - shutdown included. With Log4j this was no problem. Now it seems to be impossible. Logging shuts down, while my application is still working on it. Has anyone some hope for me? Best regards Martin 回答1: As of 2.0-beta9 this is now configurable in xml <configuration ... shutdownHook="disable"> Considering its now disabled, I guess I need to manually shutdown the

问题 I'm trying to set up an application from a third party, which requires a supporting website hosted in my local IIS. I've created a website exactly as explained in their install guide, but am having some problems, and would like to see what the IIS log has to say. Embarrassingly enough, the problem is I can't find the log files! So my question is: Where does IIS7 store logs by default? 回答1: I think the default place for access logs is %SystemDrive%\inetpub\logs\LogFiles Otherwise, check under

问题 My question is similar to : hadoop streaming: how to see application logs? (The link in the answer is not currently working. So I have to post it again with an additional question) I can see all hadoop logs on my /usr/local/hadoop/logs path but where can I see application level logs? for example : reducer.py - import logging .... logging.basicConfig(level=logging.ERROR, format='MAP %(asctime)s%(levelname)s%(message)s') logging.error('Test!') ... I am not able to see any of the logs (WARNING

问题 Is there any way We can create separate log files for different log levels. All I want is to log "error" logs to one file and "info" logs to another file. I did not find any solution to do this in log4j2.properties. Here is the log4j2.xml which I got and it works fine. Can anyone help me writing the same in properties file. <?xml version="1.0" encoding="UTF-8"?> <Configuration status="WARN"> <Properties> <Property name="log-path">logs</Property> </Properties> <Appenders> <Console name=

问题 I saw Java Logging - where is my log file?, but in my case I would like to find out in my Java application which logfile the FileHandler actually opened, i.e. if I start multiple processes and have a pattern set as java.util.logging.FileHandler.pattern=MyApp.%g.%u.log Then the %g and %u will be replaced with numbers depending on how many processes are running. I can iterate over all logging Handlers and find the File-based one. But as far as I see there is no method in FileHandler to get the

问题 I am trying to log some lines to a log files using logback. The file is correctly created and my console output is actually written in the log file. Then, I inserted some logger.debug() instructions in my code, which I don't find in my log. Why? I am using Spring Boot: @SpringBootApplication public class MyApplication { private static final Logger logger = LoggerFactory.getLogger(MyApplication.class); public static void main(String[] args) { SpringApplication.run(MyApplication.class, args); }
