*Problem* *"site" in eagle means an isolated monitored namespace for certain tenant, like a monitored cluster or service.*
In most cases, we could simply make sure a policy/application is owned by certain site, for example, alert policies are often bound with certain site which will be much easier for user to organize them, as well as applications, but there are also some special cases where polices/applications may also cross different sites, for example alert engine app in fact is shared by all sites, as well as some global overview dashboards. *Proposal* Keep a reserved "*default*" site, which means "*a globally shared namespace*", so that we could simply use consistent metadata structure for site-based / non-site / cross-site cases cases. Let's discuss about it. - Hao
