Dataset not found: nbcpu

[fragtion]

I have multiple instances of this appearing in syslog:

Feb 10 14:39:36 mail collectd[19646]: plugin_dispatch_values: Dataset not found: nbcpu (from "pc.hostname.local/cpu-total/nbcpu"), check your types.db!

What's the best approach to fix? Should types.db be edited, or can we make an adjustment to CollectM so that users don't need to edit the types.db file?
