Not in a few years, a lot of systems rely on storing only one or
two data points in a file, is OpenNMS like this(still)? I store
upwards of 20 points in a file, drastically improves scalability,
really breaks many of cacti's core assumptions that one data point
is associated to a file.

It looks like OpenNMS has a "store by group" feature to group
data points but no obvious information on what that feature does
specifically and why it may not be enabled by default.
