# Wildcard-plugin to monitor Grid Engine queue state.
|
|
# To monitor a queue, link sge_queue_xml_<queue> to this file. E.g.
|
|
#
|
|
# ln -s /usr/share/munin/plugins/sge_queue_xml_ /etc/munin/plugins/sge_queue_xml_all.q
|
|
#
|
|
# inspired by the sge_queue_ plugin committed by steveschnepp
|
|
#
|
|
# Runs 'qstat -g c -xml' for the specified queue and gets the number of
|
|
# used, reserved, unavailable, available and total queue 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.
|
|
# env.queues - list of queues to summarize
