logging

问题 I have a spring boot application, called service1, which uses the following hierarchy of property files to configure the logs: bootstrap.yml has: spring.application.name = service1 application.yml has: logging.file: /app/logs/${spring.application.name}.log logging.level.root: INFO logging.level.com.myproject.api: TRACE The log framework used is Slf4j, which is injected into every class by using Lombok's @Sfl4j annotation. spring boot claims to have default support for this, which it does, but

问题 I'm looking for some advice on logging. I've written a wrapper called Logger which internally uses Microsoft Enterprise Library 5.0. Currently it enables us to log in this way: Logger.Error(LogCategory.Server, "Some message with some state {0}", state); The problem I face is that every log in the EventViewer seems to be unrelated even though some of them are somehow related, for example they all come from processing a request from a particular client. Let me elaborate on the problem. Suppose

问题 I use the logging module in the main function/process, it works well, but it seems can't work in Actor process/subprocess. How to make it work? In the sample below code, logging.info work in the main process but failed in the worker process. Thanks. import logging import ray @ray.remote class Worker(object): ... def train(self): logging.info("fail print") ... worker = Worker.remote() ray.get(worker.train.remote()) logging.info("successful print") 回答1: There are a couple things to be careful

问题 I recently switched to Apache log4j2, and still can not find a way to configure hibernate logging using log4j2.xml. Because I can not find a way around this problem I still use log4j.properties file explicitly for hibernate. This is not the best solution since my log4j2.xml uses JPA appender (writes logs to db). I do not want to write separate logic for hibernate. Is there a way to configure hibernate logging using log4j2? 回答1: As suggested in https://issues.apache.org/jira/browse/LOG4J2-172

问题 As far as i understand log4j can handle system property -Dlog4j.debug. If you run your app with it you will get log4j's debug output. Example: java -Dlog4j.debug -jar test.jar Is there something similar for log4j 2? 回答1: Update January 2018: From Log4j 2.10, this is easy: just run your program with system property log4j2.debug (no value needed; an empty string is fine). The current (log4j-2.1) documentation on the status logger is a bit confusing. Basically: Until a configuration is found,

问题 I am trying to log the event name and parameter for each event on my Node server. For this purpose I used io.use(function(socket, next){ // how to get event name out of socket. }); Now, I got stuck while trying to get event name and arguments. To me, it looks like common demand from API dev, so I am pretty sure there must be some way to the library to get that, I have tried to read the docs and source but I am not able to get the stuff. 回答1: The socket events needs to be handled properly,in
