I'm not harping on the usefulness. More like trying to understand what would be the merit or use-case of frequent or permanent monitoring of this. Are there know failure/degradation modes from the storage HW or the filesystem, or database problems that would be detected by running this continuously. Sibling answer talks about SAN, which makes sense. Wondering what the other use-cases are here.
Otherwise, yes, of course,using it as calibration after any HW change would be interesting.
