flux dmesg [OPTIONS]
Each broker rank maintains a circular buffer of log entries which can be printed using flux-dmesg(1).
- -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.
To dump the ring buffer on all ranks
$ flux exec flux dmesg | sort
