Software Update: Zabbix 2.2.3

Version 2.2.3 of Zabbix has been released. With this program, the status of network services, servers and other network equipment can be monitored. By itself, the program can only display simple information, but more detailed information can also be obtained by installing a so-called agent on the server. More information about Zabbix can be found on this page be found and here are some screenshots. The changelog for this release looks like this:

Much more efficient SNMP monitoring
SNMP monitoring performance is significantly improved by introducing bulk requests with at most 128 items.

Much better performance with Oracle backend
You may expect more than 5x faster processing of historical data and much less resources usage by Oracle database.

Increased maximum cache size limit to 8GB
The increased memory limit allows to take advantage of physical memory with large Zabbix setups having millions of items and triggers.

Updated translations

• Portuguese
• Italian
• Japanese
• Slovakia
• Turkish
