Diese Lösung schien in manchen Fälle Probleme zu bereiten.

Folgender Weg funktioniert definitiv:

Entsprechenden Agent unter diesem Link herunter laden: http://repo.zabbix.com/zabbix/2.0/debian/pool/main/z/zabbix/

cd ~
mkdir zabbix
cd zabbix
wget http://repo.zabbix.com/zabbix/2.0/debian/pool/main/z/zabbix/zabbix-agent_2.0.6-2+wheezy_amd64.deb
dpkg -i zabbix-agent_2.0.6-2+wheezy_amd64.deb
nano /etc/zabbix/zabbix_agentd.conf

cd ~

mkdir zabbix

cd zabbix

wget http://repo.zabbix.com/zabbix/2.0/debian/pool/main/z/zabbix/zabbix-agent_2.0.6-2+wheezy_amd64.deb

dpkg -i zabbix-agent_2.0.6-2+wheezy_amd64.deb

nano /etc/zabbix/zabbix_agentd.conf

Die üblichen Änderung an der Agent konfiguration kann nun vorgenommen werden (Server IP / Log Verzeichnis / UserParameter usw.)

Der Agent wird mit
[code lang=”bash”]/etc/init.d/zabbix-agent restart[/code]
neu gestartet

Für die UserParameter fehlen noch z.B. die SmartMonTools.

Diese werden mit

apt-get install smartmontools

1	apt-get install smartmontools

nachinstalliert.

UserParameter Einstellungen befinden sich auf der Zabbix Konfigurationsseite.
