pub const SYSTEM_LINUX_MEMORY_AVAILABLE: &str = "system.linux.memory.available";Expand description
§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.
