Hi @Rui Li , can you please provide any more info to help reproduce this issue.

Hi Yunus, thanks for following up on my report. { "description": "Cassandra Cluster", "layout": [], "tags": [ "cassandra", "metrics" ], "title": "Cassandra", the 'layout' field becomes an empty array when this issue happens. This happened just randomly when I just click and enter 'cassandra' dashboard. I even manually rebuilt a second cassandra dashboard by manually recreating each panel. After one day or two. Both dashboards become empty.
I also went through docker container logs hoping to find any errors in logs. I was trying to understand where a dashboard definition(json content) is saved and how it happens that saved data could be just get lost without any explicit modifications/saving action are done from the frontend
update: this just happened again to another dashboard - 'kafka'. All I did was to click open the dashboard and all of sudden, all the panels in that dashboard are just gone. I'm on 0.30.0. not sure if this issue has been reported by other users. Please let me know of anything I can help to troubleshoot the issue. Thanks!
update: random loss of whole dashboard happened 4 times since my last report. eagerly waiting for the fix before giving up. thank you so much!

@Rui Li Are there two people using dashboards or did you open same dashboard in multiple tabs?

Hi Vishal, I did create an account for another team member. Most time I'm the only person on the portal. But I might have opened more than tab either on the same browser or different browsers. Thank you for continuing investigating this issue!
