How are logs written and rotated on an apache server?

Few questions...

1) How are logs written and rotated on an apache server? (just the idea)

2) How does a server know when to create a new log?

3) Are logs stored in a database or are they written over?

4) Where can I get information on how to analyze a log file? (valid pages views vs. hits)

1. you can use piped logs. See for description
2. if you are using piped logs you provide a rotation period or rotation size in your httpd.conf
3. logs are stored in filesystem.
4. you can use awstat ( ) to analyze apache log files.
