# Plugin for EMCs ScaleIO software. This plugins needs to be installed
# on all MDM servers as the information is provdided only by an active
# MDM member. Also it is recommended to configure a cluster host with
# these members as nodes in Check_MK and apply the ScaleIO services to
# this cluster host.

# This plugin needs a configuration file in your MK_CONFDIR. This should
# be /etc/check_mk in most cases. An example of the mk_scaleio.cfg is
# the following:
#
# SIO_USER=myUser
# SIO_PASSWORD=myPassword
