# simple_server_status

A simple and fast way to get server status on Linux systems.

## Features

All features except `conntrack` are enabled by default:

- CPU (`cpu`)
  - `cpu_usage() -> Option<f32>` (0.0..=1.0)
  - `cpu_local_usage() -> Option<f32>` (0.0..=1.0)
  - `cpu_stolen_usage() -> Option<f32>` (0.0..=1.0, useful on VPS's to measure noisy neighbors)
- Network (`net`)
  - `net_bandwidth() -> Option<u64>` (bytes/s)
  - `net_reception_bandwidth() -> Option<u64>` (bytes/s)
  - `net_transmission_bandwidth() -> Option<u64>` (bytes/s)
- RAM (`ram`)
  - `ram_usage() -> Option<f32>` (0.0..=1.0)
  - `ram_swap_usage() -> Option<f32>` (0.0..=1.0)
- TCP (`tcp`)
  - `tcp_connections() -> Option<usize>` (count)
- UDP (`udp`)
  - `udp_sockets() -> Option<usize>` (count)
- Conntrack (`conntrack`)
  - `conntrack_sessions() -> Option<usize>` (count)

Note: Must call `update()` first, to make a measurement.

## Limitations

Only supports Linux for now. Will return `Err`, `None`, or `0` on unsupported platforms,
depending on the operation.
