Our server ran out of hard drive space. We noticed that it was due to W3c logs.
We saw a forum post that said it was okay to delete them, so we did.
I found the property for Logging. I would like to know what the recommended setting is for purging log files, etc., to keep these in check.
We have never used them, nor had a need for them.
Now on to your question.
The logging you found does not control purging. Rare as it may be there is no built in feature to purge log files. What you are looking at is the basic configuration for logging.
The Log File section is pretty much what format, which fields and where you want the log files to be stored.
The Log File Rollover is basically states how often to create a new log file.
