Keyword addr

required:    false
scopable:    true
default:     224.3.29.71
rbac:        This driver group requires the root grant.

Description:

The multicast address to send to and listen on.

Keyword comment

required:    false
scopable:    false
rbac:        This driver group requires the root grant.

Description:

A free form text describing the role of the object, of the node, or of the section it is set in.

The keyword is accepted in any section, so the DEFAULT section can document a configuration as a whole, and a resource, pool, heartbeat, array or network section can document itself.

The agent does not interpret the value.

Keyword interval

required:    false
scopable:    true
default:     5s
convert:     duration
rbac:        This driver group requires the root grant.

Description:

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.

Keyword intf

required:    false
scopable:    true
rbac:        This driver group requires the root grant.

Default:

The natural interface for <addr>

Example:

intf=eth0

Description:

The interface to bind.

Keyword port

required:    false
scopable:    true
default:     10000
convert:     int
rbac:        This driver group requires the root grant.

Description:

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

Keyword timeout

required:    false
scopable:    true
default:     15s
convert:     duration
rbac:        This driver group requires the root grant.

Description:

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

Keyword type

required:    true
