logging

问题 Can anyone please suggest how to generate log files having following directory-file structure using python logging in django project. logs/2009-03-09 /errors.log /warnings.log /info.log /emails.log /messages.log logs/2009-03-08 /errors.log /warnings.log /info.log /emails.log /messages.log 回答1: Set up FileHandler instances with Filter instances which match the criteria for those files. Add the handlers to the root logger. Profit ;-) See this other answer for an example of a filter which

问题 From this StackOverflow thread, I know how to obtain and use the log4j logger in pyspark like so: from pyspark import SparkContext sc = SparkContext() log4jLogger = sc._jvm.org.apache.log4j LOGGER = log4jLogger.LogManager.getLogger('MYLOGGER') LOGGER.info("pyspark script logger initialized") Which works fine with the spark-submit script. My question is how to modify the log4j.properties file to configure the log level for this particular logger or how to configure it dynamically? 回答1: There

问题 I am currently dumping all my logging into Log4Net text files, and they are difficult to read. Is there a nice log4net processor (preferably a class I can add to my ASP.NET app, so that I can view logs remotely) that will lay out the log4net dump in a nice, easy to read and search format? 回答1: There is an Apache tool for log4j called Chainsaw which can apparently be used with log4net log files (instructions here). There is also a commercial tool called Log4Net Dashboard which can also do it.

问题 In my project sequelize logging is disabled, but I want active logging in the exact query. How can I do that? TableModel.update( {counter: 0}, {where: { id: itm.i }}, ).then((res) =>{ console.log('res',res); }).catch(e => { console.log('update error : ', e); }); I know how I can do it in findall query like this: TableModel.findAll({where: {...}, logging: console.log}) but in the update, I can't find any solution. sequelize version: 5.21 回答1: I found solution. that was so easy just adding

问题 What have others done to get around the fact that the Commons Logging project (for both .NET and Java) do not support Mapped or Nested Diagnostic Contexts as far as I know? 回答1: Exec summary: We opted to use the implementor logging framework directly (in our case, log4j). Long answer: Do you need an abstract logging framework to meet your requirements? They're great for libraries that want to play nice with whatever host environment they end up in, but if you're writing an application, you

问题 I'm using java.util.logging.Logger logging in my program. How do I enable FINE logging for a single class, while setting it to WARNING for every other class? I'd prefer to do this programatically in my main() method rather than needing to set up additional properties files. 回答1: I know the OP has asked to do this programatically but here's an example of how to do it in the properties file too. Caveat: I thought it was worthy of inclusion as the header doesn't indicate programatically and many

问题 I am using spock to test Java Spring Boot code. It gets a logback logger over the lombok @Slf4j annotation. Dummy class with log call import lombok.extern.slf4j.Slf4j; import org.springframework.stereotype.Component; @Slf4j @Component public class Clazz { public void method() { // ... code log.warn("message", new RuntimeException()); } } The Spock Spec import groovy.util.logging.Slf4j import org.junit.Rule import org.slf4j.Logger import spock.lang.Specification @Slf4j class LogSpec extends

问题 Is there a way to do the following without having to manually define the logging methods e.g. def error : object FooBar { lazy val log = LoggerFactory.getLogger("AndroidProxy") def error(msg: String) = log.error(msg) def my_method(): Unit = { error("This is an error!") } } 回答1: replace def error with import log.error 回答2: If you want to log in many classes and not rewrite the logging method every time, you can create a trait trait Logging { lazy val logger = LoggerFactory.getLogger(getClass()

问题 We have a system that uses threading so that it can concurrently handle different bits of functionality in parallel. We would like to find a way to tie all log entries for a particular "transaction" together. Normally, one might use 'threadName' to gather these together, but clearly that fails in a multithreaded situation. Short of passing a 'transaction key' down through every method call, I can't see a way to tie these together. And passing a key into every single method is just ugly. Also,

问题 We would like our application logs to be printed to files on the local nodes. We're using Log4j's RollingFileAppender. Our log4j.properties file is as follows: ODS.LOG.DIR=/var/log/appLogs ODS.LOG.INFO.FILE=application.log ODS.LOG.ERROR.FILE=application_error.log # Root logger option log4j.rootLogger=ERROR, console log4j.logger.com.ournamespace=ERROR, APP_APPENDER, ERROR_APPENDER # # console # Add "console" to rootlogger above if you want to use this # log4j.appender.console=org.apache.log4j
