LATENCY-PLOT(1)

NAME
latency-plot - another way to view latency numbers

SYNOPSIS

latency-plot [ -? | --help ] [ -H | --hal ] [ -b | --base ns ] [ -s | --servo ns ] [ -t | --time ms ] [ --relative ] [ --actual ]

DESCRIPTION

latency-plot makes a strip chart recording for a base and a servo thread. It may be useful to see spikes in latency when other applications are started or used. Mainly superseded by latency-histogram.

LinuxCNC and HAL should not be running, stop with halrun -U.

OPTIONS

-?, --help
    Show options and exit.

-H, --hal, -b, --base ns
    base thread interval in nanoseconds, default: 25000

-s, --servo ns
    servo thread interval in nanoseconds, default: 1000000

-t, --time ms
    report interval in milliseconds, default: 1000, min: 100, max: 10000

--relative
    relative clock time (default)

--actual
    actual clock time
