# This plugin monitors the usage of the Linux kernel HugePages, on some
# architectures also called Large Pages. It will show both pre-reserved
# pages (via /prc/sys/vm/nr_hugepages), their usage and reserved size, as
# pages (via /proc/sys/vm/nr_hugepages), their usage and reserved size, as
# well as HugePages allocated by the khugepaged (activated by the
# transparent_hugepages kernel command line parameter). All values are
# shown in (KiBi/MeBi/GiBi)Bytes.
