# Based on check_bond.sh written by L.Gill 10/08/06 - V.1.0 as found on
|

# http://exchange.nagios.org/directory/Plugins/Operating-Systems/Linux/check-network-bonding/details

|

#
|
||||
#
|
||||
# Example configuration
|
||||
#
|
||||
# Typical this check is placed on a client and runs via nrpe
|
||||
# So add this to nrpe.cfg:
|
||||
# command[check_bond]=/usr/lib/nagios/plugins/check_bond
|
||||
# This should warn when one of the slaves is down and go critical when the whole bond is not available.
|
||||
# This plugin defaults to bond0. If you have multiple bonds you can tell the script so by adding -i <if>.
|
||||
# It will also warn if the Currently Active Slave is not the expected primary interface,
|
||||
# the default primary interface is eth0, You can override this with -p <if>
|
||||
# -p can be a comma separated list like "-p eno49,eno50"
|
||||
|
||||
# if you have dont_blame_nrpe=1 set you can choose to
|
||||
# command[check_bond]=/usr/lib/nagios/plugins/check_bond -i $ARG1$ -p $ARG2$
|
||||
#
|
||||
# define service {
|
||||
# use generic-service
|
||||
# service_description Bond state
|
||||
# check_command check_nrpe!check_bond
|
||||
# or
|
||||
# check_command check_nrpe!check_bond!bond1
|
||||
# or
|
||||
# check_command check_nrpe!check_bond!bond1!eth1

# Who When What

# A.Swen 2011-09-07 Add support for other bond module than bond0 (defaults to bond0 however)
|
||||
# A.Swen 2013-10-11 Remove some obsolete stuff and make the script shorter
|
||||
# B.Potts 2017-01-16 Check and display expected primary interface on bond
|
||||
# J.Guldmyr 2018-09-25 Check for a list of primary interfaces instead of a single one

# Default if is bond0
