When issues occur in production LavinMQ instances, the immediate priority is to get the system back up and running. However, by the time the system is stabilized and it's safe to investigate, crucial diagnostic information (state at the time of the incident, metrics, etc.) has often been lost or overwritten.

It would be great if we can add a support-dump command to lavinmqctl that collects diagnostic information into a single archive file for troubleshooting purposes.
