Hello, it's possible to clone at least a dashboard and its widgets. Please follow the steps:
1) select the dashboard in Explore - Content menu and Export the content
2) open the XML file in text editor, find <content name="MyDashboardname" text (replace the MyDashboardname with your real dashboard name), change name of the dashboard to i.e. <content name="MyDashboardname_2" and save the document
3) import the file via "Import Content..." button, set requested permission and tick the "Overwrite content" checkbox => the dashboard is "duplicated"
Some widgets can be updated in the XML document too (for example Search Query in Top-N widgets can be changed from <searchQuery>vm.host.name:Host1*</searchQuery> to <searchQuery>vm.host.name:Host2*</searchQuery>) but it's recommended that configuration of each widget should then be done manually.
Let me know if it works well.
That worked quite well, thanks! While not a 100% ideal solution, it will save me LOADS of time - you have my appreciation for that.
