The statistics are only accesible if you are logged in and to put all that
in your own page is not inmmediate.
If you can make an app that takes a screenshot of your sunstone screen and
serves it to the public that could be one easy way.
Second dirty way would be to try deploy a second sunstone server whose
dashboard and layout are hacked in a way that it only shows the statistics
(hiding the menu, top/bottom bars). I never tried to deploy a second
server for the same install of ONE, but I think it should be possible.
Hacking would be done in layout.js and dashboard-tab.js files mostly. You
can hack sunstone-server.rb so that login happens automaticly with the
credentials you want and perform relogin if session exprires.
And programatically, it is not so straightforward. Dashboard statistics
are build by processing and regrouping the data that comes when the list
of Hosts, VMs... is fetched. This is done in monitoring.js which groups
and plots the information according to configurations defined in the
SunstoneMonitoringConfig object.
So this approach would be a bit of a hell if you're not familiar with the
code:
1 - add a custom route to the sunstone server that generates the stats
page you want to show.
get '/stats' do
#perhaps turn session expiration of here
erb :stats, :layout => false
end
The generated html should contain the <div>s where you would like to paint
the things. You can try copying that from dashboard-tab.js.
2 - Include opennenbula.js, monitoring.js and all the jquery* vendor
libraries. Create a new stats.js file. After you login in sunstone, you
can directly go to http://sunstone-ip:port/stats Your stats.js will need
to make use of OpenNebula.Host.list(params) and similar to get a list of
resources. In the params you need to include a callback function.
3 - your stats JS should include the SunstoneMonitoringConfig['HOST'] You
can copy it from hosts-tab.js. The only part I think you need to edit is
the plot() function inside it, which indicates where the plots are going
to be painted ("container").
4 - Within the callback function for Host.list() you should call
SunstoneMonitoring.monitor('HOST', host_list)
(see updateHostsView() in hosts-tab.js, which is the callback for
Host.list())
5 - If the steps above are ok then the pies and diagrams for hosts should
be painted in your stats page in the divs that you placed. If you want VMs
stats, you need to get the VMs list, the SunstoneMonitoringConfig['VM']
object and repeat the process.
I keep wondering if maybe I missed an easy brighter way to do this. I'll
write back if it cames to my mind.

Hi,
I would like to share the diagrams and statistics from sunstone
(dashboard host panel) on a public webpage. Is there an easy way to do
this?
Thank you for your answears!
