High Availability Status - Field Help

Current Statistics

To refresh the values, including the list of reach targets, click Refresh Statistics.

Node
The address of the local host machine and it's current role: primary or secondary.

Port
The port through which the partner and the node share high availability communication

Partner
The address of the partner high availability machine.

Recovery Strategy
Choose between:
  • Auto--the primary machine resumes load balancing as soon as it comes back into service.
  • Manual--the primary machine acts as standby for the backup machine and does not resume routing packets until the administrator issues a takeover command.

State
The current state of the primary host machine. Possible values are:
  • Active - this machine is load balancing packets
  • Standby - this machine is not load balancing packets; it is monitoring the state of an active Load Balancer
  • Idle - this machine is load balancing packets, and is not trying to establish contact with a partner Load Balancer
  • Listen - this machine is listening for communication from a backup Load Balancer

Sub State
The current sub-state of this machine; only applies if you have started to configure high availability. Possible values are:
  • Synchronized - this machine has established contact with another Load Balancer
  • Not Synchronized - this machine is trying to establish contact with another Load Balancer, but has not yet succeeded

Heartbeat Pair
A list of the heartbeat pairs which include the:
  • Heartbeat source address -- The address of the high availability partner machine that sends heartbeats. This address should be defined on the physical adapter of the node that you wish to use to monitor the health of the Controller.
  • Heartbeat destination address -- The destination address is the address of the high availability partner machine to which heartbeats and responses are sent. This address should be defined on the physical adapter of the node that you wish to use to monitor the health of the Controller.

List of reach targets
Current list of reach addresses, their associated local and partner status. Note: Reach targets are only visible after they have been added.


Configuration Settings

Heartbeat Interval
The frequency with which "heartbeat" packets are exchanged with the partner node. The default is 500 milliseconds.

Heartbeat Takeover Interval
The amount of time that expires, during which no heartbeat packets are sent or received, before a takeover can occur. The default is 2000 milliseconds.

Log file name
The name of the high availability log file.

Logging level
The verbosity of messages for the switch that is running. The range is None to Verbose, with None meaning nothing is logged and Verbose meaning everything is logged. The default value is minimal. Note that this is a different log than the Manager log. You can select these values:
  • None
  • Minimal
  • Basic
  • Moderate
  • Advanced
  • verbose

Log size (bytes)
A number indicating the size of the log, in bytes. The default is 1048576.
