Documentation ¶

Overview ¶

Package sysstat samples host metrics (CPU, memory, swap, disk, network) from /proc on Linux. On platforms without /proc (e.g. local dev on macOS) the readers fail softly and return zeros — the panel still runs.

Functions ¶

func ProcMem ¶

func ProcMem() int64

ProcMem returns the panel process's resident set size (RSS) in bytes, read from /proc/self/status. 0 if unavailable.

Types ¶

type Sampler ¶

type Sampler struct {
	// contains filtered or unexported fields
}

Sampler maintains rolling CPU% and network rates via a background ticker.

func New ¶

func New(diskPath string) *Sampler

New starts a sampler that refreshes CPU/network rates every 2s.

func (*Sampler) Read ¶

func (s *Sampler) Read() Stats

Read returns the current snapshot (cheap; on-demand for mem/disk/uptime).

type Stats ¶

type Stats struct {
	CPUPercent float64 `json:"cpu_percent"`
	MemUsed    int64   `json:"mem_used"`
	MemTotal   int64   `json:"mem_total"`
	SwapUsed   int64   `json:"swap_used"`
	SwapTotal  int64   `json:"swap_total"`
	DiskUsed   int64   `json:"disk_used"`
	DiskTotal  int64   `json:"disk_total"`
	HostUptime int64   `json:"host_uptime"` // seconds
	NetUp      int64   `json:"net_up"`      // bytes/sec
	NetDown    int64   `json:"net_down"`    // bytes/sec
}

Stats is a point-in-time host snapshot. Byte fields are absolute; Net* are per-second rates.
