#Milky2018/sysinfo

A MoonBit-native system metrics and process inspection library for Linux and macOS.

#Status

  • native target only.
  • Linux: fully supported.
  • macOS: fully supported.
  • Other OSes: unsupported semantics (is_supported_system == false, APIs return None, empty collections, or no-op defaults instead of panicking).

#Install

moon add Milky2018/sysinfo

#Quick Start

let system = @sysinfo.System::new_all()

println("supported=\{@sysinfo.is_supported_system}")
println("total_memory=\{system.total_memory()}")
println("used_memory=\{system.used_memory()}")
println("cpu_usage=\{system.global_cpu_usage()}")
println("process_count=\{system.processes().size()}")

#Refresh Semantics

sysinfo-style delta metrics require at least two refreshes with an interval:

  • CPU usage
  • Network traffic deltas
  • Process CPU usage

MINIMUM_CPU_UPDATE_INTERVAL is fixed to 200 ms.

let system = @sysinfo.System::new_all()
system.refresh_cpu_usage()

sleep(220)

system.refresh_cpu_usage()
let usage = system.global_cpu_usage()

#Main API Surface

  • System: System, RefreshKind, CpuRefreshKind, MemoryRefreshKind, ProcessRefreshKind
  • Process: Process, Pid, Uid, Gid, ProcessStatus, ThreadKind, Signal, KillError
  • CPU: Cpu
  • Disks: Disks, Disk, DiskKind, DiskRefreshKind, DiskUsage
  • Networks: Networks, NetworkData, MacAddr, IpNetwork
  • Components: Components, Component
  • Users/Groups: Users, User, Groups, Group
  • Globals: is_supported_system, MINIMUM_CPU_UPDATE_INTERVAL, supported_signals

#Process Control

Supported process-control APIs:

  • Process::kill()
  • Process::kill_with(signal)
  • Process::wait()
  • Process::kill_and_wait()
  • Process::kill_with_and_wait(signal)

On unsupported systems, these return unsupported-safe values (None/Err(KillError::Unsupported)), matching the library's non-panicking downgrade policy.

#Notes

  • set_open_files_limit and System::open_files_limit follow upstream behavior:
    • Linux: implemented.
    • macOS: set returns false; query may return a system limit when available.
  • supported_signals exposes the signal list supported by this binding.
