The charts in statistics reference: /hosts?search=os_description=~VAL1~ That only contains "all hosts" and not "content hosts". As we have no "all hosts", all the charts are blank.

Created attachment 1004506 [details] present content hosts
Since this issue was entered in Red Hat Bugzilla, the release flag has been set to ? to ensure that it is properly evaluated for this release.
One of the features being introduced as part of Satellite 6.2, is "Host Unification". It is basically the unification of the Host and Content Host. With this feature, for any content host that gets created, there will always be an associated host (as the content is just a 'facet' of the host). This means that as far as statistics are concerned, any applicable statistics will be included. That said, for a base content host that doesn't have puppet, this may be fairly limited (e.g. only OS and arch).
Verified in Satellite 6.2 Beta Snap 8 Compose 1. All applicable statistics are now reported for content hosts.
