How do I reduce OS stat's for PI

Hi Chaps,

We are seeing large quanties of statistics being created in PI at the O/S level - some 30-50MB per hour on average in directory /usr/sap/<SID>/<Instance>/data which is filling the filesystem.  This seems an excessive amount of data being recorded, so do we know how to reduce the amount of statistics being generated?

Thanks,

Graham
