Thanks for the suggestion, I did install dstat earlier while trying to
figure things out on my own. However, I think my kernel being the
older version does not support the latest feature the website was
pointing out. Given that it's a live server not within physical touch,
I'm a little wary of doing kernel updates that might just kill it :D

I'll try other methods first and see if they help, if not, I'll
probably have to bite the bullet and do it over a weekend where I get
more time to repair any inadvertent damage.
