Add percent column in README log examples

Problem/Motivation

I wanted to add a percent column, and ended up with this, after many experiments:

for i in $(seq -f "%02g" 0 59); do printf "%02d" ${i#0}; grep "/2026:13:$i:" /var/log/apache2/access.log | awk '{if ($9 == 429) {limited++} else {served++}} END {limited != 0 ? percent = ((limited/NR)*100) : percent = 0; printf("%6d %6d %6d %6d%\n", NR, served, limited, percent) }'; done

... so this is what I added:

; limited != 0 ? percent = ((limited/NR)*100) : percent = 0
... and
%6d%
... and
, percent. The result:

00   188    108     80     42%

It could get added to the last example like this:

# Print total, served, number and percent of rate-limited requests for each
# minute in a given hour.
# This example uses 17th hour (5 pm) on 15/Jun/2025. Period from 17:00 to 17:59.
# Columns:
#   - Hour in a day (in 24-hour format)
#   - Total number of requests
#   - Number of allowed/served requests
#   - Number of rate-limited requests.
#   - Percent of rate-limited requests.
for i in $(seq -f "%02g" 0 59); do printf "%02d" ${i#0}; grep "15/Jun/2025:17:$i:" /var/log/access.log | awk '{if ($9 == 429) {limited++} else {served++}} END { limited != 0 ? percent = ((limited/NR)*100) : percent = 0; printf(" %6d %6d %6d %6d%\n", NR, served, limited, percent) }'; done
