fileappender

I have started exploring Logback option for our application. One of the requirement is to create a separate log file for log entries that have a specific "Marker". Below is the logback.xml file that i am using and the error I am getting. The examples on the logback website shows the usage of SMTPAppender but I would like to use FileAppender instead. Is this possible? If not, what other option do i have? <property name="USER_HOME" value="c:/temp" /> <appender name="AUDIT_FILE" class="ch.qos.logback.core.FileAppender"> <evaluator class="ch.qos.logback.classic.boolex.OnMarkerEvaluator"> <marker

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 locked by another process (thread). A better way for log4net to do this would be to have a single thread

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. 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. Prepending to a file on the other hand is rather expensive. The entire file has to be read and rewritten

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 One text file , where some other components are reading this file content and doing some process. By

I am using Log4j as logging framework in a project I am working on. I have the following situation: Log4j is configured to write the logs into a log file. At some point, this log file is copied to another destination and deleted. Logging framework keeps working, but the logs are not written to the log file because it is deleted. Is there any way to tell Log4j to recreate the file and keep writing the logs into the log file. Best regards, Rashid I study the source of log4j and find log4j can't create new log file, it just print the error message to system.err when the log file was deleted /**

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? Jon Skeet 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 fine. 来源： https://stackoverflow.com/questions/1294668/log4net-fileappender-not-thread-safe

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.FileAppender"> <file>myapp.log</file> <encoder><pattern>%logger{35} - [%F:%L] - %msg%n</pattern><
