VMIO column on hobbitmon.com 🔗 link

I was wondering how you know what to set your thresholds at for the primary
and secondary stats.  I assume it has something to do with the size of the
server but is there a way to calculate it.  Like I have 8 gig of ram and 4
sparc processors so is there a way to calculate these variables for the bmio
column.

 
Thanks,

Josh
