Cumulative jiffies a CPU (the aggregate, or one core) has spent in each state
since boot: user nice system idle iowait irq softirq steal guest guest_nice.
The trailing fields were added across kernel versions (iowait/irq/softirq
in 2.6, steal in 2.6.11, guest in 2.6.24, guest_nice in 2.6.33); any
column absent on an older kernel defaults to 0.
Summary
Functions
Build from the integer columns of a cpu/cpuN line. Missing trailing
columns default to 0; any beyond guest_nice are ignored.
Jiffies spent not doing work: idle + iowait.
Total jiffies across every state - the denominator of a utilization ratio.
Types
@type t() :: %Sys.Linux.Proc.Stat.CpuTimes{ guest: non_neg_integer(), guest_nice: non_neg_integer(), idle: non_neg_integer(), iowait: non_neg_integer(), irq: non_neg_integer(), nice: non_neg_integer(), softirq: non_neg_integer(), steal: non_neg_integer(), system: non_neg_integer(), user: non_neg_integer() }
Functions
@spec from_columns([non_neg_integer()]) :: t()
Build from the integer columns of a cpu/cpuN line. Missing trailing
columns default to 0; any beyond guest_nice are ignored.
@spec idle(t()) :: non_neg_integer() | float()
Jiffies spent not doing work: idle + iowait.
@spec total(t()) :: non_neg_integer() | float()
Total jiffies across every state - the denominator of a utilization ratio.
