hb.multicast

Minimal configlet:

[hb#1]
type = multicast

Minimal setup command:

om test/ccfg/foo set --kw="type=multicast"

addr

required:    false
scopable:    true
default:     The ipaddr resolved for the nodename.

Example:

addr = 1.2.3.4

The addr to use to connect a peer. Use scoping to define each non-default address.

interval

required:    false
scopable:    true
default:     5s
convert:     duration

The maximum interval between 2 heartbeat payload sends.

The actual interval is not fixed, because the daemon tries to send the message as soon as it has something to notify. A minimum interval protects the node from saturating the network and cpu with the daemon synchronization workload.

intf

required:    false
scopable:    true
default:     The natural interface for `<addr>`

Example:

intf = eth0

The interface to bind.

port

required:    false
scopable:    true
default:     10000
convert:     int

The port for each node to send to or listen on.

timeout

required:    false
scopable:    true
default:     15s
convert:     duration

The delay since the last received heartbeat from a node before considering this node is gone.

type

required:    true
scopable:    false
candidates:  unicast, multicast, disk, relay

The heartbeat driver name.
