#
# Wildcard-plugin to monitor Sun Grid Engine queue state.
# To monitor a queue, link sge_queue_<queue> to this file. E.g.
#
#   ln -s /usr/share/munin/plugins/sge_queue_ /etc/munin/plugins/sge_queue_all.q
#
# Based on the condor_queue_ plugin by Šarūnas Burdulis.
#
# Runs 'qstat -g c' for the specified queue and gets the number of
# used, reserved, unavailable and free queue slots.
# Free slots are defined as available slots minus reserved slots.
# Unavailable slots have queue states Disabled/Suspended/Error/Ambiguous config/Unknown
#
# Parameters understood:
#
#   config   (required)
#   autoconf (optional - used by munin-config)
#   suggest  (optional - used by munin-config)
#
# Configurable variables:
#
#   env.sge_settings - Path to SGE settings.sh script, defaults to /opt/sge/default/common/settings.sh
#   env.title        - Graph title, overrides "SGE Queue state".
#   env.options      - Additional command line options to qstat.
