Description |
We have a page at https://www.zabbix.com/documentation/2.4/manual/appendix/items/vm.memory.size_params that lists available parameters for vm.memory.size[] key. However, some descriptions are very platform-specific. For instance, the following is correct on BSD systems only, even though "available" is supported on every platform:
This page should probably be improved so that it describes the platforms on which a particular parameter is supported and it should describe the meaning of a particular parameter on a particular platform. |

A survey of memory statistics retrieval, depending on platform:
Please note that in two cases the value cannot be calculated from other metrics: On all platforms, "pavailable" is calculated as "available"/"total"*100 Win32"free" = ms_ex.ullAvailPhys Solaris"free" = _SC_AVPHYS_PAGES Mac OS X"active" = vm.active_count Tru64"free" = free OpenBSD"active" = uvm.active NetBSD"active" = uvm.active FreeBSD"active" = "vm.stats.vm.v_active_count" Linux"free" = info.freeram HP UX"free" = pdy.psd_free AIX"pinned" = m.real_pinned | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
