Sistemoje turėtų būti jau sudiegtas [[rrdtool]] ir [https://github.com/sivel/speedtest-cli speedtest-cli].

Padarome RRD duombazę:
<syntaxhighlight lang="bash">
rrdtool create speedtest.rrd \
  --step 1800 \
  DS:download:GAUGE:3600:0:1000 \
  DS:upload:GAUGE:3600:0:1000 \
  DS:ping:GAUGE:3600:0:500 \
  RRA:AVERAGE:0.5:1:48 \
  RRA:AVERAGE:0.5:6:336 \
  RRA:AVERAGE:0.5:48:365
</syntaxhighlight>

Duombazės atnaujinimui panaudojame šį skriptą:
<syntaxhighlight lang="bash">
#!/bin/bash
RRD=speedtest.rrd
MAX_RETRIES=3
RETRY_DELAY=10
timestamp=$(date +"%Y-%m-%d %H:%M:%S")

run_speedtest() {
    local attempt=1
    while [ $attempt -le $MAX_RETRIES ]; do
        result=$(speedtest --secure --server 1437 --json 2>/dev/null)
        exit_code=$?
        if [ $exit_code -eq 0 ] && [ -n "$result" ]; then
            echo "$result"
            return 0
        fi
        sleep $RETRY_DELAY
        attempt=$((attempt + 1))
    done
    return 1
}

result=$(run_speedtest)
if [ $? -ne 0 ]; then
    echo "[$timestamp] Data retrieval !!!failed!!! -> $result"
    download="NaN"
    upload="NaN"
    ping="NaN"

ping=$(echo "$result" | jq '.ping' | awk '{print int($1 + 0.5) }')
echo "[$timestamp] Data retrieval !!!ok!!! -> Download: $download Upload: $upload Latency: $ping"
fi

rrdtool update $RRD N:$download:$upload:$ping
