#

# 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. 

#

# Revisions:
