Function sys_metrics::host::get_host_info

pub fn get_host_info() -> Result<HostInfo, Error>

Get some basic HostInfo of the host.

On linux and macOS it will get the os_version and hostname from uname.

For the uptime/loadavg/memory on linux it will get them from sysinfo. But on macOS it will use the crate get_loadavg and get_memory and a special get_uptime function using an unsafe syscall.
