# gp_gbl_mem - Munin plug-in to fetch global memory utilisation via Glance
#	      (should only run on HP-UX with GlancePlus (GP) installed therefore)
#
# Requires:   Separate GP adviser syntax file whose location is made known
#             by ADVISER environment variable which defaults to
#             @@LIBDIR@@/gp_gbl_mem_util.adv.
#
#             Configuration for this plugin may look like this, the example
#             shows the defaults, so only set them to override them.
#             All the environment settings are needed by Glance.
