fileappender

问题 Is is possible to configure FileAppender in log4net to add new entries at the beginning of log file? Currently it is adding entries at the end and reading newest entries requires scrolling whole log down. It would be more comfortable to read from the beginning. 回答1: I don't know if that option is available in log4net (I wouldn't think so), but even if it's available I would advice against using it. Appending to a file is a quite cheap operation. The bytes are just added to the end of the file

问题 I have a requirement that I need to store audit information in a TEXT file . I planned to write the audit information using Apache Log4j . Seems to be reliable option. But, I should be able to write the Audit information even the fileSize reaches 3GB. Does the log4j supports the fileSize even at GigaBytes ?. Or with a Quick Question, What is the MaximumFileSize can be supported in Log4j . NOTE : I could not go for RollingFileAppender or DailyFileAppender, I need to log the information Only in

问题 Hello sir: When server is started ,the log files print the output statement..how can i print the log files in my own file? 回答1: Configure a log4j properties file with file appender. Something like this - log4j.rootLogger=WARN, fileAppender log4j.logger.myPackage=DEBUG, fileAppender log4j.additivity.myPackage=false log4j.appender.fileAppender=org.apache.log4j.RollingFileAppender log4j.appender.fileAppender.File= C://Myfile.log log4j.appender.fileAppender.MaxFileSize=1024KB log4j.appender

问题 TickZoom is a very high performance app which uses it's own parallelization library and multiple O/S threads for smooth utilization of multi-core computers. The app hits a bottleneck where users need to write information to a LogAppender from separate O/S threads. The FileAppender uses the MinimalLock feature so that each thread can lock and write to the file and then release it for the next thread to write. If MinimalLock gets disabled, log4net reports errors about the file being already

问题 I need to log to a file because the customer doesn't have a console of something where I can log to with log4net. Now I read that the FileAppender is not thread safe. Is there anyhow a way to log to file within an app that logs out of different threads or what would be a common alternative? 回答1: Log4Net itself is thread-safe even if FileAppender isn't - the framework manages everything for you. So long as you log in the normal way (rather than directly writing to the appender) you should be

问题 I have the following configuration file that is very similar to the standard example in the Logback manual. The only difference is the addition of [%F:%L]. while everything works, %F and %L do not work. If I remove the async appender and log directly using the file appender, everything works just great. can somebody explain what is going on? And how to print the file name and line number as these two parameters are supposed to? <configuration> <appender name="FILE" class="ch.qos.logback.core

问题 I'd like a very simple XML configuration file with a console and a file appender using log4j2. (The Apache Website is killing me with much Information.) 回答1: <?xml version="1.0" encoding="UTF-8"?> <Configuration status="INFO"> <Appenders> <Console name="Console" target="SYSTEM_OUT"> <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" /> </Console> <File name="MyFile" fileName="all.log" immediateFlush="false" append="false"> <PatternLayout pattern="%d{yyy-MM-dd HH:mm

问题 I have two csv files result.csv and sample.csv. result.csv M11251TH1230 M11543TH4292 M11435TDS144 sample.csv M11435TDS144,STB#1,Router#1 M11543TH4292,STB#2,Router#1 M11509TD9937,STB#3,Router#1 M11543TH4258,STB#4,Router#1 I have a python script which will compare both the files if line in result.csv matches with the first word in the line in sample.csv, then append 1 else append 0 at every line in sample.csv It should look like M11435TDS144,STB#1,Router#1,1 and M11543TH4258,STB#4,Router#1,0

问题 While it is not difficult to setup different log files, each with a different conversionPattern, per level, I would like to have minimal logging for all but errors, where I'd like a detailed log entry. Here's a snippet of my current configuration: <appender name="WarningsAndBelowFileAppender" type="log4net.Appender.FileAppender"> <file value="log.txt" /> <appendToFile value="false" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%m%n" /> </layout> <filter type=

问题 Forget for a second the question of why on earth would you do such a thing - if, for whatever reason, two FileAppenders are configured with the same file - will this setup work? 回答1: Log4j's FileAppender does not allow for two JVM's writing to the same file. If you try, you'll get a corrupt log file. However, logback, log4j's successor, in prudent mode allows two appenders even in different JVMs to write to the same file. 回答2: It doesn't directly answer your question, but log4*net*'s
