Thanks, cpu now works ok. I still have a problem with NFS ops. I can only guess it might be due to the fact that this filer unlike the others has been up 34 days and done 2,725,616,890 nfs ops (some time ago the nfs ops rolled back over to 0 after being up a few months, a problem I reported to NetApp). I'll reboot it tonight and see if that makes a difference.

For some reason, the #!<path_to_perl> at the top of the script bin/retrieve-cpu.pl was not changed during installation. It still had #!/usr/local/bin/perl5, which is not where I have it installed. The other scripts were fine, though. It's a very good tool, I recommend it.
