This check runs bgpctl show and checks that all bgp sessions are up.

sample outputs :

• Ok

$ check_openbgpd
CHECKBGPCTL OK - All bgp sessions in correct state | 'PEER-1'=529581;;;0

Sometimes you have some peer sessions in idle state, and it 's not critical. Typically a session which depends on a slave carp interface. You have an option '--idle-list', the plugin will take care if the session is in this list, and returns an 'OK' state for this session.

$ check_openbgpd --idle-list PEER-2 OTHER-PEER
CHECKBGPCTL OK - All bgp sessions in correct state | 'PEER-1'=529581;;;0 'PEER-2'=0;;;0 'OTHER-PEER'=0;;;0

• Critical

Critical state is reached with first idle session not escaped in the optionnal '--idle-list'

$ check_openbgpd
CHECKBGPCTL CRITICAL - OTHER-PEER is U (outside range 0:) | 'PEER-1'=529918;;;0 'OTHER-PEER'=U;;;0

• Unknown

if an error occured during the check, the plugin raises a check error, which returns an UNKNOWN state.

typically UNKNOWN causes

• OpenBGPD is not running

CHECKBGPCTL UNKNOWN - host.domain.tld bgpctl: connect: /var/run/bgpd.sock: No such file or directory

• you're not in the wheel group, and can't read the bgpctl sosk

CHECKBGPCTL UNKNOWN - host.domain.tld bgpctl: connect: /var/run/bgpd.sock: Permission denied

sudo is your friend to run this plugin with an unprivileged user. A sample config here

icinga ALL = NOPASSWD: /usr/local/bin/check_openbgpd

extract the tarball and

python setup.py install

Maybe you have installed setuptools with

pkg_add py-setuptools

then just

easy_install checkopenbgpd

check_openbgpd is located at /usr/local/bin/check_openbgpd

check_openbgpd could be called localy or remotely via check_by_ssh or NRPE.

check_by_ssh

here a sample definition to check remotely by ssh

Command definition

define command{
    command_name    check_ssh_bgpctl
    command_line    $USER1$/check_by_ssh -H $HOSTADDRESS$ -i /var/spool/icinga/.ssh/id_rsa -C "sudo /usr/local/bin/check_openbgpd --idle-list $ARG1$"
}

the service itself

define service{
    use                     my-service
    host_name               hostname
    service_description     bgpctl
    check_command           check_ssh_bgpctl!
}

NRPE

add this line to /usr/local/etc/nrpe.cfg

...
command[check_openbgpd]=/usr/local/bin/check_openbgpd
...

nagios command definition

define command{
    command_name    check_nrpe_bgpctl
    command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c check_openbgpd -a "--crit-list $ARGS1"
}

the service itself

define service{
    use                     my-service
