Module sysinfo 

Sysinfo data collection loop: collects CPU, memory, and network metrics and publishes them via the WPS broker. Sampling interval is configurable via the telemetry:interval setting (0.1s–2.0s, default 1.0s).

Structs

NetState 🔒

Network I/O tracking state for rate calculations.

Constants

BYTES_PER_MB 🔒

DEFAULT_INTERVAL_SECS 🔒

MAX_INTERVAL_SECS 🔒

MIN_INTERVAL_SECS 🔒

PERSIST_COUNT 🔒

Functions

get_cpu_data 🔒

Collect CPU usage (total + per-core).

get_disk_data 🔒

Collect disk I/O rates (in MB/s). sysinfo Disk::usage() returns deltas (bytes since last refresh) so we divide by elapsed time to get rates.

get_interval_secs 🔒

Read the telemetry interval from config, clamped to [MIN, MAX].

get_mem_data 🔒

Collect memory metrics (in GB).

run_sysinfo_loop

Run the sysinfo collection loop. Uses tokio::time::interval for steady tick rate regardless of refresh duration. Interval is re-read from config each tick and the timer is reset if it changes.
