+# HugePages monitoring plugin for munin
+#
+# 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
+# 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.
+#
+# This plugin is used like many other munin plugins: put it in
+# /usr/share/munin/plugins (or another appropriate location)
+# and create a symlink in /etc/munin/plugins:
+# > ln -s /usr/share/munin/plugins/hugepages /etc/munin/plugins
+# Then restart munin-node.
