Saved dashboards can be shared via the URL in your brower’s navigation bar. Dashboards persisted to Elasticsearch will have a URL that points to them, such as:
In this example
MYDASHBOARD is the title we have given the dashboard
You can also share links to adhoc dashboards by generating a temporary URL to them by clicking the Share icon in the upper righthand corner of Kibana.
By default these temporary URLs live for 30 days.
