logging

问题 java.util.logging.Logger class provides ability to use such a syntax: int i=0; log.log(Level.INFO,"int i = {0}", i); This will print out "int i = 0". Unfortunately when I have a bigger value, like 9093, it will print out "int i= 9,023" separating each 3 digits with comma. The question is how should I get rid of thoose commas? Preferably changing insides of {}. Tried both {0:d} and {0:%d}. Both didnt help. Is it even possible to control parametres like this? Or should I convert my int to

问题 I want to create Handler that will be catch all Logs of web aplications on Tomcat, I Created my Handler class, compiled it and put on $CATALINA_HOME/lib , and common.loader has this directory. After this I modified the logging.properties file and added the handler: handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler, logshowaplication

问题 I need to use a constant defined in the standard library socket in a logging configuration file. Problem, when reading the config file with logging.config.fileConfig() it ends with: NameError: name 'socket' is not defined My question is very close to this one, the difference is that if, as a workaround, I import the missing library (e.g. socket ) from the main script reading this logging configuration file, it doesn't solve the problem (is this because I use python3?). Complete logging

问题 I've a simple scala app (not using Play MVC framework) but that uses play.api.Logger I'm trying to figure out the pattern I need to add to include the File and Line where the log was done. This was the logback.xml I was using from the start: <configuration> <conversionRule conversionWord="coloredLevel" converterClass="play.api.Logger$ColoredLevel"/> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%date %-16coloredLevel %message %n</pattern> </encoder> <

问题 I got an error message saying: This exception has been logged with id 1mhqg4onc But I don't see this exception in the logs. I only have myapp.DEBUG , myapp.ERROR , myapp.FATAL , myapp.INFO , myapp.TRACE and myapp.WARN in my myapp/logs directory. I thought application.log was just supposed to be there by default. It's in my local machine but not when I deploy to production and that's where this exception is happening. I tried adding a file at conf/application-logger.xml with the default

问题 Added a custom column as suggested here. Things are working fine when ever I log something into this column using the code line log4net.GlobalContext.Properties["CustomColumn"] = "Custom value"; But if I pass null instead as below log4net.GlobalContext.Properties["CustomColumn"] = null; this is logged as (null) (a string null included in brakets). This also happens if I do not log at all, like I comment the code as shown below. //log4net.GlobalContext.Properties["CustomColumn"] = null; So the

问题 I wrote a script that executes commands in parallel. I let them all write an entry to the same log file. It does not matter if the order is wrong or entries are interleaved, but i noticed that some entries are missing. I should probably lock the file before writing, however, is it true that if multiple processes try to write to a file simultaneously, it will result in missing entries? 回答1: Yes, if different processes independently open and write to the same file, it may result in overlapping
