# `Sys.Mon.Cpu`
[🔗](https://github.com/harmont-dev/hyper/blob/main/lib/sys/mon/cpu.ex#L1)

Monitors instantaneous CPU utilization (the soft beta_vcpus signal).

Samples `/proc/stat` every 23 ms and reports the busy fraction
(`0.0..1.0`, normalized across all cores) between consecutive reads - never the
load average, which has different semantics. The first read only establishes a
baseline (`:skip`). Readings are smoothed with a 30-second time constant
(sampling fast only de-noises the filter; the smoothing window is set by `tau`).

# `value`

```elixir
@spec value() :: Sys.Mon.Server.Reading.t()
```

The latest instantaneous + filtered CPU utilization (fractions `0.0..1.0`).
