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(1).
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
