Some things to look out for
- long ranges where the Disk Util is around 98% (i.e. more than a minute or so) when the filer does *nothing else* (i.e. no SnapMirror, no backup, not much client activity goig on etc.) might indicate problems with disks or RAID layout
- multiple consecutive CP Types with a capital B should also be avoided (generally, when you see ~5 or so consecutive B's you might have a problem with your aggregates)
Note that these only *hint* to problems, they are not definite indications
