OK.

A 19:15-öst lekéstem, a 20:16-os ez, itt most lement a mérés:

A mérőscript:
"#!/bin/sh
sleep 5
logger -t meroscript "Hardware server IP: 185.72.16.2"
LATENCY=$(speedtest lat http://185.72.16.2/speedtest/latency.txt 10 2>/dev/null)
DOWNLOAD=$(speedtest down http://185.72.16.2/speedtest/random_1gb 400 30 33333 30 10 1 2>/dev/null)
UPLOAD=$(speedtest up http://185.72.16.2/speedtest/upload.php 28 30 33333 30 30 1 2>/dev/null)
echo "$DOWNLOAD $UPLOAD $LATENCY""

Szerintem a script jó így ránézésre.
