flux-dmesg(1)

SYNOPSIS

flux dmesg [OPTIONS]

DESCRIPTION

Each broker rank maintains a circular buffer of log entries which can be printed using 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 "always", "never", or "auto". If WHEN is omitted, "always" is used. When the option is not used, the default is "auto", or "never" if NO_COLOR is set to a non-empty value in the environment.

EXAMPLES

To dump the ring buffer on all ranks

$ flux exec flux dmesg | sort
