Server requirements and a couple of questions

Hi,

Please see this comment: Hardware requirements for a Grafana server - #2 by torkel

Yes, you can assign users the global role Viewer, see permission documentation. Starting from Grafana 5.0 you’ll be able to add permissions for users and groups to dashboards and folders, see what’s new in Grafana v5.0.

Per default Grafana supports 7 panel types, see graph panel documentation and links in left menu to the other panel types. Please see Official & community built plugins where you’ll find a pie-chart panel among many others.
