I have been looking at NodeStats / FsStats and as far as I understand only
'path.data' is being reported (REST API, JMX). Would it make sense to
include also 'path.work' if it can play any role in system performance in
general? I do not know what kind of data is stores in work directory but if
IO performance can impact search or index operations, it would be useful to
see this information in FsStats as well.
