OCF_PACEMAKER_IFSPEE(7)

NAME
ocf_pacemaker_ifspeed - Network interface speed monitor

SYNOPSIS

OCF_RESKEY_name=string [OCF_RESKEY_iface=string] [OCF_RESKEY_ip=string] [OCF_RESKEY_bridge_ports=string] [OCF_RESKEY_weight_base=integer] [OCF_RESKEY_dampen=integer] [OCF_RESKEY_debug=string] ifspeed [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

Every time the monitor action is run, this resource agent records (in the CIB) (relative) speed of network interface it monitors. This RA can monitor physical interfaces, bonds, bridges, vlans and (hopefully) any combination of them. Examples: *) Bridge on top of one 10Gbps interface (eth2) and 802.3ad bonding (bond0) built on two 1Gbps interfaces (eth0 and eth1). *) Active-backup bonding built on top of one physical interface and one vlan on another interface. For STP-enabled bridges this RA tries to some-how guess network topology and by default looks only on ports which are connected to upstream switch. This can be overridden by 'bridge_ports' parameter. Active interfaces in this case are those in "forwarding" state. For balancing bonds this RA summs speeds of underlying "up" slave interfaces (and applies coefficient 0.8 to result). For non-balancing bonds ('active-backup' and probably 'broadcast'), only the speed of the currently active slave is used.

SUPPORTED PARAMETERS

OCF_RESKEY_name = string [ifspeed]
    Attribute name

    The name of the attribute to set. This is the name to be used in the constraints.

OCF_RESKEY_iface = string []
    Network interface

    Network interface to monitor.

OCF_RESKEY_ip = string []
    IPv4 or IPv6 address

    Try to detect interface name by detecting the interface that holds the IP address. The IPv4 (dotted quad notation) or IPv6 address (colon hexadecimal notation) example IPv4 "192.168.1.1". example IPv6 "2001:db8:DC28:0:0:FC57:D4C8:1FFF".

OCF_RESKEY_bridge_ports = string [detect]
    Bridge ports

    If not null and OCF_RESKEY_iface is a bridge, list of bridge ports to consider. Default is all ports which have designated_bridge=root_id.

OCF_RESKEY_weight_base = integer [1000]
    Weight of 1Gbps

    Relative weight of 1Gbps in interface speed. Can be used to tune how big attribute value will be.

OCF_RESKEY_dampen = integer [5]
    Dampening interval

    The time to wait (dampening) for further changes to occur.

OCF_RESKEY_debug = string [false]
    Verbose logging

    Log what have been done more verbosely.
