logging

问题 I added two handlers with different formatters to my logger. The first one requires subclassing logging.Formatter to do custom formatting. The default formatter will suffice for the second handler. Let's say the first formatter simply removes newline characters from the message. The following script illustrates what seems like strange behavior: import logging logger = logging.getLogger(__name__) class CustomFormatter(logging.Formatter): def __init__(self, *args, **kwargs): super().__init__(

问题 Is it possible to get the logger wrapped by slf4j ? For example, in debug mode, when I inspect org.slf4j.LoggerFactory.getLogger(loggerName) , I can see the logger (here, java.util.logging ) : I want to do something like : // Get the real logger, cast in java.util.logging java.util.logging.Logger myLogger = LoggerFactory.getLogger(loggerName))...; // Use the java.util.logging methods myLogger.setLevel(Level.parse(level)); 回答1: I've found a solution using reflection. Looking for the "logger"

问题 I am evaluating if it is possible to leverage C++11 features to replace logging Macros without any run-time additional cost. I come out with this demo: enum class LogLevel { Fatal = 0, DFatal = 1, Error = 2, Normal = 3, Verbose = 4, Debug = 5 }; constexpr LogLevel log_compiled = LogLevel::Normal; LogLevel log_runtime = LogLevel::Error; #ifdef NDEBUG constexpr LogLevel log_fatal = LogLevel::Fatal; #else constexpr LogLevel log_fatal = LogLevel::DFatal; #endif template <LogLevel L, typename std:

问题 I'm using docker-compose.yml that launches my services. All services look something like this: A-service: image: A-service restart: always network_mode: host logging: driver: journald options: tag: "{{.ImageName}}/{{.Name}}/{{.ID}}" fluent-bit: image: 'bitnami/fluent-bit:latest' restart: always network_mode: host command: /fluent-bit/bin/fluent-bit -c /fluent-bit/etc/fluent-bit.conf volumes: - ./service/config/fluent-bit.conf:/fluent-bit/etc/fluent-bit.conf - type: bind source: /run/log

问题 I am new to SSIS, I have already designed a package and configured SSIS Log provider for Text Files. This works fine and log files are generated successfully. We have a monitoring team, they use this log file for monitoring. They are unable to read the log files since the file encoding is in Unicode format. They are expecting a non unicode format for their monitoring. I tried to change the existing log file encoding to ANSI but when I re-run the package my log file has been created again with

问题 TL;DR If I'm using JsonLayout with a nested KeyValuePair in my log4j2.xml config the resulting log messages are empty. Any ideas why? Long Story I'm using Tomcat 8.5.43 with the following logging related JARs: jackson-annotations-2.9.7.jar jackson-core-2.9.7.jar jackson-databind-2.9.7.jar slf4j-api-1.7.25.jar jcl-over-slf4j-1.7.25.jar log4j-api-2.12.0.jar log4j-core-2.12.0.jar log4j-jul-2.12.0.jar log4j-slf4j-impl-2.12.0.jar tomcat-extras-juli-8.5.2.jar (as tomcat-juli.jar in /bin) tomcat

问题 I want to modify the python logging to log the time elapsed from when the script started (or when the logging module was initialized). 000:00 DEBUG bla bla 000:01 ERROR wow! ... this is measured in minutes:seconds I found the relativeCreated variable in the logging module, but this is givving me millisecond accuracy which would only spam the logs, making harder to see where the time goes or how log it took to run. How can I do this? 回答1: You can use a logging.Formatter subclass which gets the

问题 I'll start with the code: var s = ["hi"]; console.log(s); s[0] = "bye"; console.log(s); Simple, right? In response to this, Firebug says: ["hi"] ["bye"] Wonderful, but Chrome's JavaScript console (7.0.517.41 beta) says: ["bye"] ["bye"] Have I done something wrong, or is Chrome's JavaScript console being exceptionally lazy about evaluating my array? 回答1: Thanks for the comment, tec. I was able to find an existing unconfirmed Webkit bug that explains this issue: https://bugs.webkit.org/show_bug

问题 I am trying to log the errors and warnings of an R script into an external file. At the same time I want to be able to see the errors and warnings in the console in RStudio (useful to develop and debug). I am trying to use the following code: logfile <- file("my_file_path", open="wt") sink(logfile, type="message", split = TRUE) But when I try to split the message connection using the funciton sink() I get the following error: Error in sink(logfile, type = "message", split = TRUE) : cannot

问题 Objective: prevent schedule from logging every time it runs. Background: I am using the logging and schedule libraries in a python project. My log file contains information about the physical state of a instrument run by a Raspberry Pi, and is updated every 10 seconds. I use the schedule library to schedule that periodic log. Here is the limited documentation I have found for schedule . The Problem: The schedule library logs this statement, every time it runs a job. 2016-06-29 09:01:51,022
