Monitoraggio di dischi SMART con Zabbix

• Installare smartmontools

apt-get install smartmontools

• Copiare lo script di discovery:

mkdir -p /etc/zabbix/scripts; wget "https://raw.githubusercontent.com/v-zhuravlev/zbx-smartctl/master/discovery-scripts/nix/smartctl-disks-discovery.pl" -O /etc/zabbix/scripts/zabbix-smartctl-disks-discovery.pl; chmod +x /etc/zabbix/scripts/zabbix-smartctl-disks-discovery.pl

• Aggiungere il file sudoers:

echo "zabbix ALL= (ALL) NOPASSWD: /usr/sbin/smartctl,/etc/zabbix/scripts/zabbix-smartctl-disks-discovery.pl" > /etc/sudoers.d/zabbix-smartctl-disks
chmod 0440 /etc/sudoers.d/zabbix-smartctl-disks

• Testare l'esecuzione via sudo

sudo -u zabbix sudo /etc/zabbix/scripts/zabbix-smartctl-disks-discovery.pl 

• Installare lo userparameter:

wget "https://raw.githubusercontent.com/v-zhuravlev/zbx-smartctl/master/zabbix_smartctl.conf" -O /etc/zabbix/zabbix_agentd.d/zabbix-smartctl-disks.conf
sed -i -e 's_/etc/zabbix/scripts/smartctl-disks-discovery.pl_/etc/zabbix/scripts/zabbix-smartctl-disks-discovery.pl_' /etc/zabbix/zabbix_agentd.d/zabbix-smartctl-disks.conf

• Riavviare zabbix agent

systemctl restart zabbix-agent.service

• Da server o proxy zabbix, testare:

zabbix_get -s machine.name -k uHDD.discovery
zabbix_get -s machine.name -k uHDD.health[/dev/sda]

• Installare sul server il template https://raw.githubusercontent.com/v-zhuravlev/zbx-smartctl/master/Template_3.4_HDD_SMARTMONTOOLS_2_WITH_LLD.xml
