Hi, Here are the mockup UIs for Visualizing the CouchDB Clusters. It is just the initial UIs.
* Page 1-cluster.png* [https://app.box.com/s/isjbfop69j2cmz0kg0qar7l5nmupjnf l This Page visualize nodes in the clusters with summary information for each node. (Name, Memory usage..etc..) with a nice web UI interface. It is interactive (drag and drop supporting over nodes) *Page 2-cluster-notification-tip.png [* https://app.box.com/s/euc5megmx5lwseqib4511309ocoypryb <https://app.box.com/s/euc5megmx5lwseqib4511309ocoypryb>] Top of each panel of the nodes it contains a notification icon if there is notification. eg: Memory/disk space availability, Error in node etc... Notification will have a simple drop down structure as it is showing. *Page 3-cluster-warning.png* [ https://app.box.com/s/f2ljwxvz2w01f8uepsj4zyarhwbpiz8b] Critical level alert is showen. (Alert level can be set in config and notification center) *Page 4-adding-new-node.png* [ https://app.box.com/s/noygbeyze792bh4t93iaoxywdciau057] By clicking "add new node" you can add new nodes for clusters. UI Consistency is maintained *Page 5-adding-new-node-by-drag-drop.png*[ https://app.box.com/s/gbfsbwb6zt1jdkijve72mnullplecpj7] User interface is supported for drag-drop of databases in nodes. (replication operation in the BE) *Page 6-selected-db-in-node.png*[ https://app.box.com/s/6ojrvpxuvmo9k18dlnf8i4nmibzdx5s9] Each node shows the databases in it. By Clicking on database you can see detailed view of a particular database. This allows users to understand memory/data/doc distribution over DBs in particular nodes. *Page 7-custer-mgt-center.png* [ https://app.box.com/s/t9s42g3gwvv6bocbdsxrgjimdrh2ty0z] Each node is shown with disk usage under icon and summary text of the node is also given. It is easy to identify the disk space - free availability. (In here we need some BE services help) *Page 8-custer-mgt-center-infor.png* [ https://app.box.com/s/vvo4v9ji79l8japo3nm9f4lfbjhdamkc] User can customize notifications for each nodes by level (warning, infor, etc..) *Page 9-charting-disk-usages.png*[ https://app.box.com/s/fk7eyoyrtg8d3b29xoo0mdho9rr8cmyz] Cluster usage of the system is shown as a bar chart and the attributes to be shown can be selected according to user's preferences. You ideas are welcome in here.
