There's an observability and workflow management UI: https://docs.dbos.dev/java/tutorials/workflow-management
You can view your workflows and queues, search/filter them by any number of criteria, visualize graphs of workflow steps, cancel workflows, resume workflows, restart workflows from a specific step--everything you'd want.
Currently, this is available as a managed offering (Conductor - https://docs.dbos.dev/production/self-hosting/conductor), but we're also releasing a self-hostable version of it soon.
