# Requirements:
# - lmstat
#
# Note:
# - You must provide the daemon name as it is listed in the flexlm license
# if you want it displayed differently use the LMDISPLAYNAME variable
#
2009-08-10 17:41:59 +02:00
# Parameters supported:
# - config
# - autoconf
#
2009-08-10 17:41:59 +02:00
# Configuration variables
# - LMFEATURES: The individual features of each vendor daemon to graph.
# If no features are given, all features
# reported by vendor daemon are treated to graph.
2009-08-10 17:41:59 +02:00
# - LMDISPLAYNAME: use the LMDISPLAYNAME instead of the daemon name when
# generating graph names
# - LMGRAPHISSUED: If set generate a graph of the number of licenses issued for
# each feature.
# - LMSTAT: The path to the lmstat binary
2009-08-10 17:41:59 +02:00
# - LMLICFILE: The path to the FlexLM License File
# - LMLOGARITHMIC If set then graph use a logarithmic scale
