First of all I really like the Dashboards in Opsview and I heavly use them.
There are a few things I noticed:
Having a lot of Dashboards has quite an impact on the general loading time of the Dashboard section. As we have an Account which owns lots of Dashboards which are shared and shouldn't be deleted maybe add an option to just hide some of the Dashboards without deleting them.
We have a lot of redundant servers so it's often the case that we have two ore more systems on which we want to monitor the exact same stuff. There is already the possibility to clone Dashlets but for example on a Performance Graph I cant edit the already added Series (on a clone the series of the original server) so I have to create every Series for every Host again and again to just change the Host. It would be totally awesome and would save me a lot of work if you could add a feature to edit existing series.
It would be really nice if you could add a feature to the Performance Graphs to set and show a certain Range and/or the Threshholds of a Graph.
Keep up the good work!
