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.
