Constant SYSTEM_LINUX_MEMORY_AVAILABLE 

pub const SYSTEM_LINUX_MEMORY_AVAILABLE: &'static str;

Description

An estimate of how much memory is available for starting new applications, without causing swapping

Notes

This is an alternative to system.memory.usage metric with state=free. Linux starting from 3.14 exports “available” memory. It takes “free” memory as a baseline, and then factors in kernel-specific values. This is supposed to be more accurate than just “free” memory. For reference, see the calculations here. See also MemAvailable in /proc/meminfo
