Frequently Asked Questions

I have downloaded and installed LOG4VIEW. How can I start? 

First, make sure that your logging application is configured to write log messages using log4net. If you just want to test LOG4VIEW, you can use the application LogEmiter.exe which is installed together with LOG4VIEW. Then, just drag your application exe file from the file explorer to LOG4VIEW. Confirm the settings in the receiver configuration form and press OK. Now, LOG4VIEW is configured to receive messages from your application.

I have created a receiver in LOG4VIEW but I don't get any messages. 

Make sure, that your application is configured to write log messages. Examine the settings of the log4net root logger. Make sure, that no Log4Net filter prevents the reception or display of log messages.

Which appender/receiver should I use for LOG4VIEW? 

LOG4VIEW works with the standard UDP appender, with file and rolling file appenders and with a special LOG4VIEW TCP appender. If the log messages shouldn't be persisted, use the TCP appender. It works on the local machine as well as with remote applications. All you need is an open TCP port. If you need to store your logging information, use the RollingFileAppender. LOG4VIEW can read consecutive rolled files at once and reads the current log file as it is written without locking the file so that it can be rolled over by log4net.

I have configured my application to send messages with the TCP appender but I don't get any messages. When I use the file appender, everything works fine. 

Make sure, that the file prosa.LogAppender.dll is in the same directory as your logging application.

I am using Windows 7 and am trying to receive Messages using the UDP appender. But I don't get any messages.

Log4net has a bug in the UDP appender so that you can't send messages to the local IP address 127.0.0.1 in Windows 7. A workaround is to use the local address "127.0.0.2".

Which message layout should I use? 

Use XML layout whenever possible. It is best suited to be read by LOG4VIEW. LOG4VIEW can also read pattern formatted log files but it can't be ensured that LOG4VIEW can read every log pattern, because some patterns are ambiguous.
