# NOTE: Careful when replacing the *-import below with a more specific import. This can cause
# problems because it might remove variables from the check-context which are necessary for
# resolving legacy discovery results such as [("SUMMARY", "diskstat_default_levels")]. Furthermore,
# it might also remove variables needed for accessing discovery rulesets.

# FIXME
# The WATO group 'memory_simple' needs an item and the service_description should
# have a '%s'.  At the moment the current empty item '' and 'Memory' without '%s'
# works but is not consistent.  This will be fixed in the future.
# If we change this we loose history and parameter sets have to be adapted.
