Question

Is it possible to write from 5 different processes to the same log file?

I am using Log4Net for logging, but seems like only 1 process is writing to the file, when I shut this process down, the 2nd process is writing.

I want all to write together.

How to?

Answer 1

If you want to write to a single file from multiple processes add the MinimalLock as LockinModel to your <appender> node:

<appender .... >
  ......
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
  ......
</appender>

Beware this have some impact on the performance.
