Добавим в Nagios проверку RAID при помощи nrpe и вот этого скрипта check_afacli

В этом скрипте обращаем внимание на следующие параметры

use lib "/usr/lib/nagios/plugins"; # если у вас 32 битная система;
# use lib "/usr/lib64/nagios/plugins"; # если у вас 64 битная система;
my $SUDO = '/usr/bin/sudo'; # путь к sudo
my $AFACLI = '/usr/sbin/afacli'; # путь к afacli
my $AFASCRIPT = '/etc/nagios/afascript';
my $AFALOG = '/tmp/afacli.log';

Что из себя представляет /etc/nagios/afascript. Это набор команд которое необходимо проделать скрипту

# vi /etc/nagios/afascript
logfile start '/tmp/afacli.log'
open afa0
controller details
container list /all /full
enclosure show slot
close
logfile end
exit

Сделаем файл исполняемым и перенесем в папку

/usr/lib/nagios/plugins для 32-битных систем
/usr/lib64/nagios/plugins"для 64-битных систем
# chmod +x check_afacli
# mv check_afacli /usr/lib/nagios/plugins

Проверим скрипт

# /usr/lib/nagios/plugins/check_afacli
OK: Battery:Ok 0:RAID-5:546GB:OK

Добавим на хост машине в /etc/nagios/nrpe.cfg

command[check_afacli]=/usr/lib/nagios/plugins/check_afacli

Перестартуем nrpe

# service nrpe restart

На сервере Nagios в /etc/nagios/hosts/TEST.cfg пропишем проверку сервиса

Перестартуем Nagios
