Also, I have a module that has only one line of getLogger.

This getLogger is a info().

I would like to log ONLY this piece to my new file.

There are others thread about this subject but they got no answers.

Hi maugzoide , do you want to record all the getLogger’s info methods input to a file ? Do you develop a custom module or ask for configuration ?

Connection counts , active streams , published streams can be handled with custom modules .

Here is an example of logging connection info to C:/file.txt .

Hi,

Please see this thread

> [@Logging custom module to a different file](http://community.wowza.com/t/-/43813):
>
> Is there any way to log (getLogger) to a different file? Wowza logs every information inside access.log. I would like to log my custom module to a different file.

You will need to go through the example provided to implement for your environment.

Andrew.

Thanks for the answer.

I am developing a custom module.

Sorry, I forgot to mention that I would like to use log4j to rotate my logs.

The way the above snippet acts does not use log4j so I would manually rotate it (a thing that I don’t want to).
