NIDP.YYYY-MM-DD.xml Logs

Can someone clarify for me what is responsible for creating the NIDP.YYYY-MM-DD.xml daily logs in /var/opt/novell/nam/logs/mag/nesp/nidplogs on the AG?

I was looking at a system and noticed it is generating 3-4GB of logs in there every day.  Is that generated by Auditing settings?  Or what generates those?

Thanks.
