Making sense of the output in a graphical way

assuming you got sysstat installed already

Send to TSDB with Fluent-Bit

maybe you would prefer to parse specific commands' output to fluent-bit then vmetrics.

Built-in performance graphs

switch to sar command line options by specifying --

vi ~/sysstat-graphs.bash

#!/bin/bash

mkdir -p /var/www/html/sysstat/
cd /var/www/html/sysstat/
sadf -g -s 00:00:00 -e 23:59:59 -T -- -u > cpu.svg
