calculate rate of new lines in log

per min

stdbuf -oL tail -f /var/www/golang/logs/2025-04-27/esb_worker_db_queue_peertopeer_0_404012_2_access.log | \
> stdbuf -oL grep -oP '"time":"\K[^"]+' | \
> stdbuf -oL awk -F'[:T.]' '{print $2":"$3}' | \
> stdbuf -oL uniq -c | \
> while read count minute; do
>     echo "Rate for $minute: $count logs";
> done

per second
