logging

问题 I'm trying to migrate my application from the beautiful Logrus (very helpful for debug) and introducing the Uber log framework Zap. With Logrus, i can initialize the logger only once and reuse it from other Go file, an example: package main import( // Print filename on log filename "github.com/onrik/logrus/filename" // Very nice log library log "github.com/sirupsen/logrus" ) func main(){ // ==== SET LOGGING Formatter := new(log.TextFormatter) Formatter.TimestampFormat = "Jan _2 15:04:05

问题 I use ElasticSearch High-Level Client Java API in my Spring Boot application. I want to log the queries built using High-Level client API for debugging purposes. My question is what kind of settings required in my application.properties file to turn on JSON queries built from my application? I tried out the following properties to the application.properties file. However, it does not print the JSON queries built using various query builders. logging.level.org.elasticsearch.client=TRACE

问题 I have the following issue: I have an application, which continuously produces output to stderr and stdout. The output of this application is captured in a logfile (the app is redirected as: &> log.txt ). I don't have any options to produce a proper logging to file for this. Now, I have a cron job, which runs every hour and beside of doing other things, it also tries to rotate this logfile above, by copying it to log.txt.1 and then creates an empty file and copies it to log.txt It looks like:

问题 What's the correct approach to log both an error message and an exception using SLF4J? I've tried doing this but the exception stack trace is never printed: logger.error("Unable to parse data {}", inputMessage, e); In this case I want to populate {} with the inputMessage as well as logging out the exception stacktrace. The only way I can see to do this would be to do this: logger.error("Unable to parse data " + inputMessage, e); which is not pretty. 回答1: As of SLF4J version 1.6, SLF4J will

问题 I got an exception with a stack trace containing the following line my.company.Service$$$view26.myMethod(Unknown Source) Can anybody help me to understand what the $$$view part means? We are using JBoss EAP 6.4 and Java 8. 回答1: A dollar sign ( $ , one or multiple) means that it is a generated class. CDI (Weld 1.x in case of EAP 6.4 you are using) is one of the 'frameworks' which uses this pattern. It creates proxies based on your classes in order to allow for interception decoration and bean

问题 I have been following Logging in ASP.NET Core Which is working just fine. I have a question about this line _logger.LogWarning(LoggingEvents.GetItemNotFound, "GetById({ID}) NOT FOUND", id); I am wondering why they are not using $ - string interpolation? _logger.LogWarning(LoggingEvents.GetItemNotFound, $"GetById({ID}) NOT FOUND"); Why would the LogWarning extension have a params object[] args paramater? Whats the point when you can just send everything in string message. I assume there is a
