I am unable to create a local snapshot of a dashboard with 38 panels that display data from MySQL… Can a dashboard be too big to create a snapshot? It tries for about five minutes.
I also read a question about snapshot security. IT appears like a local snap shot is secure because it does not show the option to edit the query. Is this correct? I’m attempting to display a demo dashboard on my website.
I’m not going to pursue this further but I thought someone in the future might want to know the cause.
‘dashboard’ in the dashboard_snapshot table is mediumtext which is 16MB. So the string gets truncated at 16MB. Changing the value to longtext also did not work because I think it times out while attempting to create the local snaphhot,.
