Met het programma Zabbix kun je verschillende onderdelen van een netwerk en de daarop aangeboden services in de gaten houden. Het programma ondersteunt twee verschillende mogelijkheden om de relevante informatie binnen te halen. Zo kan het vanaf zijn eigen host requests sturen naar de verschillende services en netwerkonderdelen, die daar vervolgens op reageren. Ook is er een zogeheten agent, die op de te bewaken host kan worden geïnstalleerd en waarmee gedetailleerde informatie kan worden binnengehaald. Voor meer informatie over Zabbix verwijzen we naar deze en deze pagina's. De ontwikkelaars hebben versies 1.9.0 alpha en 1.8.4rc2 uitgebracht met de onderstaande lijst aanpassingen:

What's New in 1.9.0

Low level discovery
Zabbix is able to discover your file systems, network interfaces and SNMP interfaces automatically with no manual work. One template can be used for hosts having different devices.

Optional graph legends
Graph legend can be optionally disabled.

Templated host-level screens
Templates may contain screens for easy maintenance. The screens are available via Monitoring->Hosts, yet the form is not finished yet.

Database integrity
There are significant improvements in the database schema for better consistency and security of configuration and historical data.

Nanosecond resolution for historical data
Zabbix supports nanosecond resolution for historical data. If you are migrating from 1.8.x the option will be off by default. It is on for fresh setups.

Multiple URLs for map elements
A map element may have multiple links (URLs) to external resources.


What's New in 1.8.4

More consistent Zabbix API
Zabbix API was improved to have much more consistent method names and handling of parameters. Zabbix API documentation was massively improved. It is available at http://www.zabbix.com/documentation/1.8/api.

Support of DB2
DB2 database is supported as Zabbix back-end database. Therefore Zabbix users have a choice of five database engines currently: Oracle, DB2, PostgreSQL, MySQL and SQLite. See documentation for DB2 specific installation instructions.

NTLM authentication for WEB monitoring
Zabbix WEB monitoring supports NTLM authentication.

Sending of SMS notifications via Ez Texting services
A new way of sending SMS messages was added to Zabbix. You may take advantage of a commercial SMS provider for reliable messaging in the US and Canada.

User macros enhanced
User macros were extended so that they can be used in both trigger and item names.
