Some cases:

  1. User deployed SSM agents on some nodes with adding their host names in conf/agents. After SSM cluster becomes active, all nodes should be correctly described on node info page, i.e., live or dead.
  2. For dead nodes in the 1st item, after user successfully launches them, their state should become live in node info page.
  3. User tries to scale out active SSM cluster by deploying agents on some new nodes, these new nodes should also be correctly described on node info page, i.e., live or dead.
  4. The configured standby server should also be correctly displayed. If the standby server crashes, its state on node info page should be dead. After successfully launched, the standby server's state should become live again.
  5. Considering two Smart Server are configured, if the active Smart Server is dead, the standby server will work as active server. The node info page should reflect this change. User can relaunch the Smart Server that once serves as active server. After relaunched, it will work as standby Smart Server. The node info page should also correctly reflect each node's role.
