logging

问题 I'm maintaining a Maven project that uses log4j 1.x with a large codebase. Not only is log4j 1.x used in existing code, it is also used by some third party libraries on which the project depends. I want to start using log4j 2 now, but I wonder if it is worth the hassle. I know it is possible to mix the two (cf. Mixing log4j 1.x and log4j 2) but what about the third party libraries that depend on log4j 1.x, I'm afraid there will be conflicts. So should I rather stick to log4j 1.x or risk a

问题 I have a project using .NET Framework ASP.NET Core 2.0, and want to implement logging to windows event log, like i read here Add log providers public class Program { public static void Main(string[] args) { BuildWebHost(args).Run(); } public static IWebHost BuildWebHost(string[] args) => WebHost.CreateDefaultBuilder(args) .ConfigureLogging((hostingContext, logging) => { logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging")); logging.AddEventSourceLogger(); logging

问题 I have set the logging level in the spring boot application in application.yml as: logging.level.com.Myapplicationname=DEBUG The application is packaged and deployed as war on tomcat. Apart from this I haven't set the logback.xml to define the log file etc. Please tell me where can I see the console logs when some user uses the application over the browser. Is there any default file created by framework. 回答1: You should either specify logging.file or logging.path , but not both ( when both

问题 We are using: Spring Boot Slf4J Logback ELK stack Now we want to use MDC to add the unique tracking number, which is provided in the POST request JSON, to every log statement for a given request. I googled some blog posts, those are not useful for me much. Below is the logback.xml which we are using <configuration> <property name="PROJECT_ID" value="template-api"/> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder class="net.logstash.logback.encoder.LogstashEncoder

问题 I wrote a small-ish Python script that handles nightly conversions and archiving of audio data. Since there have been some unexpected problems along the way (non-existing files, unreliable connection to the database server and so on...), I added Python's own logging facility to keep track of any encountered problems. The problem is, the log file is created wherever the script is run from (e.g. current working directory), so I have two logfiles, one in my homedir (which is used when the script

问题 I want to prevent maven from displaying INFO messages, I want to see only WARNINGS and ERRORS (if any). How can I achieve this, preferably by changing the command line that calls maven? 回答1: Answering your question I made a small investigation because I am also interested in the solution.

问题 I see here http://socket.io/docs/logging-and-debugging/ that if I want to run logs, I do like this: DEBUG=* node yourfile.js this works. But I want to also run process with forever. https://www.npmjs.com/package/forever But now actually I do not even know if I need forever. Then intention of running forever was - if server dies - forever restarts it. But the problem is that server dies, clients cannot connect and forever does not restart it. Then node process is using socket.io. So as I

问题 I am using logging.info to output information about what my script is doing and I am using logging.basicConfig(level=logging.INFO) to enable this. And this ( logging.basicConfig(level=logging.INFO) ) also affects other modules I invoke (e.g. SQLAlchemy) causing a way much more verbose output than I want. Can I set the logging level to INFO for my actual script but not for the 3rd-party modules it uses (I'd prefer it to be WARNING for them)? 回答1: The normal way to do this is to define a logger
