All OS templates have been updated to include memory graph. 15 5.20 Network discovery changes Starting with Zabbix 2.2.0 hosts discovered on different entering of long e-mail addresses. Overall frontend and API memory usage was decreased by optimising database access function and reducing its memory usage by 22-95%. Previously, enabling debug mode for guest

When working in low memory mode value cache will attempt to switch back to normal operational mode once per day. The current getting double alerts. vm.memory.size[available] item on AIX now returns the sum of free and cached memory. Before Zabbix 3.0 only the free memory size was returned. vm.memory.size[available] item on Linux

Proxy memory buffer A memory buffer has been developed for Zabbix proxy. The memory buffer allows to store new data (item values, network discovery the use of memory buffer on the proxy. This is possible by modifying the value of ProxyBufferMode from ”disk” (hardcoded default for existing installations) to ”hybrid” (recommended) or ”memory”. It is

Swap size is now calculated from the total memory space available (physical and virtual memory combined). Although these results are more accurate than they were before translations to be displayed by default. 13.1.2 Performance improvements 26 • Improved performance and memory usage in screens with a large amount of screen elements 13.1.3 Dashboard host status widget • Previously

See supported by platform and vm.memory.size parameters pages for more information. 5.3.2 Note that monitoring a large amount of disks will increase the memory usage. • Previously, Zabbix agents allocated a static amount of memory for monitoring 8 disks or partitions. This amount is now dynamic
