Stopped JavaEE agents and removed agents from Agent Status dashboard. Still getting alarms like these:
Agent "<Agent Host - Agent Name>" (id: null) is broken (health state: "Agent Info Not Present")
Object is not deleted.
1. Go to Management Server -> Servers -> Data Management
2. Expand Host Model -> Hosts -> <Host name> -> Agents
3. Delete the agent object listed that is no longer in use.
See attached screenshot for example.
