A simple elementary script to monitor the request count for each source ips at seconds granularity by grepping the haproxy-info log

#!/bin/bash
COLUMNS=300
export COLUMNS
source_ips=( "10.0.0.1" "10.0.0.2" "10.0.0.3")
header=("Time" ${source_ips[@]})
for value in "${header[@]}"; do
                printf "%-8s\n" "${value}"
        done | column -x
for i in $(seq -w 1 60);
do
        results=()
        results+=("$1$i")
        for ip in ${source_ips[*]};
        do
                results+=(`grep "$1$i" $2 | grep $ip | wc -l`)
        done
        for value in "${results[@]}"; do
