To access the Daemons view, click the Daemons tab. The Daemons view displays the following information for each daemon you are monitoring:

Daemon Group
Name of the daemon group.
Daemon
Name of each daemon in the group. All daemons in a group must have the same name.
Group State
Combined state of all the daemons in the group. The summary group state depends upon the initial high availability pattern set for the daemon group.
Summary Group States for Active/Active Groups Summary Group States for Active/Standby Groups
  • Active if at least one daemon is Active
  • Passive if all daemons are Passive
  • Out of Service (OOS) if there are no daemons in Active state and at least one daemon is OOS
  • Active if one and only one daemon is Active. Other daemons can be in any state.
  • Passive if:
    • No daemon is in an active state.
    • Zero or more daemons are in standby states.
    • No daemon is out of service.
    • One or more daemons are in a passive state.
