flux-dmesg(1)

SYNOPSIS

flux dmesg [OPTIONS]

DESCRIPTION

Each broker rank maintains a circular buffer of log entries which can be printed using :program`flux dmesg`.

OPTIONS

-C, --clear

Clear the ring buffer.

-c, --read-clear

Clear the ring buffer after printing its contents.

-f, --follow

After printing the contents of the ring buffer, wait for new entries and print them as they arrive.

-n, --new

Follow only new log entries.

-H, --human

Display human-readable output. See also --color and --delta.

-d, --delta

With --human, display the time delta between messages instead of a relative offset since the last absolute timestamp.

-L, --color[=WHEN]

Colorize output. The optional argument WHEN can be auto, never, or always. If WHEN is omitted, it defaults to always. The default value when the --color option is not used is auto.

EXAMPLES

To dump the ring buffer on all ranks

$ flux exec flux dmesg | sort
