       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

       This agent's monitor action records the speed of a specified network interface as a node
       attribute. The attribute can be used in rules to prefer nodes based on network speeds.
       This agent can monitor physical interfaces, bonded interfaces, bridges, VLANs, or any
       combination thereof. For example: *) 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 agent tries to determine the network topology, and by default
       looks only on ports which are connected to an upstream switch. This can be overridden by
       'bridge_ports' parameter. Active interfaces in this case are those in "forwarding" state.
       For balancing bonded interfaces, this agent uses 80% of the sum of the speeds of
       underlying "up" ports. For non-balancing bonded interfaces ("active-backup" and probably
       "broadcast"), only the speed of the currently active port is considered.

SUPPORTED PARAMETERS

       OCF_RESKEY_name = string [ifspeed]
           Attribute name

           Name of the node attribute to set

       OCF_RESKEY_iface = string []
           Network interface

           If this is set, monitor this network interface. One of iface or ip must be set.

       OCF_RESKEY_ip = string []
           IPv4 or IPv6 address

           If this is set instead of iface, monitor the interface that holds this IP address. The
           address may be specified in dotted-quad notation for IPv4 (for example, 192.168.1.1)
           or hexadecimal notation for IPv6 (for example, 2001:db8:DC28:0:0:FC57:D4C8:1FFF). One
           of iface or ip must be set.

       OCF_RESKEY_bridge_ports = string [detect]
           Bridge ports

           If set and iface is a bridge, consider these bridge ports (by default, 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 more verbosely.
