# Using ID_SERIAL attribute for naming disks in collectd results in
# data about the whole disk and each partition being mixed together
# incorrectly, see: https://github.com/collectd/collectd/issues/823
#
# The rules below provide a ID_COLLECTD attribute instead, which
# differentiates between the whole disk and its particular partitions.
