Speedtest-rrd

Panaudojimas: Tinklo greičio pasiremiant speedtest.net matavimas kas 30min ir loginimas/atvaizdavimas.

Sistemoje turėtų būti jau sudiegtas rrdtool ir speedtest-cli.

Padarome RRD duombazę:

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

Duombazės atnaujinimui panaudojame šį skriptą:

#!/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!!! -> $result"
    download="NaN"
    upload="NaN"
    ping="NaN"
else
download=$(echo "$result" | jq '.download' | awk '{print int($1 / 1250000) + 0.0 }')
upload=$(echo "$result" | jq '.upload' | awk '{print int($1 / 1250000) + 0.0 }')
ping=$(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

Grafiko piešimui panaudojame šį skriptą:
