The issue isn't reproducible for the master branch. The grafana dashboards are being able to share/export, except for "Ceph-Cluster" grafana dashboard which is throwing timeout error.

To my knowledge, this is a configuration option that needs to be enabled at build time in Grafana and depends on the PhantomJS headless web browser, which makes the Grafana installation quite "heavy". I'm not sure that's a pure Ceph Dashboard issue.
I suggest to resolve this issue as "Won't fix", as it's primarily a Grafana configuration issue and therefore out of scope for Ceph Dashboard.
Instead, let's create a new feature tracker that implements an option to take a screen shot of an embedded Grafana image using the browser's built-in screen capture API, as Ernesto suggested during today's stand-up.

Looks as if that API is not really intended to be used for creating still image screen shots of a given browser area. I was not able to find an existing API that support this, but there's some work in progress here: https://github.com/fernap3/screenshot
