Inkscope is a Ceph admin and supervision interface. It relies on a nosql solution. We use mongodb to store real time metrics and history metrics but not on the same collection. Each collection is ruled by a TTL.
The main folders are:
documentation contains diagram of inkScope architecture, datamodel...
inkscopeViz : GUI to visualize Ceph cluster status (dashboard) and and relations between Ceph cluster objects and manage of a ceph cluster
inkscopeCtrl : server part for inkscopeAdm and inkscopeViz
inkscopeProbe : probes to collect information about the cluster (Ceph and system info)
inkscopeMonitor : for supervision of Ceph
Manual installation is described in the inkScope wiki
