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.
