Ceilometer Database Size Check.
The undercloud’s ceilometer database can grow to a substantial size if metering_time_to_live and event_time_to_live is set to -1 (infinite). We check each setting and fail if -1 is set.
Undercloud Services Debug Check.
The undercloud’s openstack services should _not_ have debug enabled. This will check if debug is enabled on undercloud services. If debug is enabled, the root filesystem can fill up quickly, and is not a good thing.
