自宅 → インターネット宛てのスループットを定点観測する為に Raspberry Pi へ Smokeping をインストールしました。 今回は Smokeping のインストール手順から初期設定までをメモしておきます。 尚、今回はスループットをモニタしたいだけなので、アラーム検出時のメール送信は設定しません。
インストール
Raspbian OS であれば標準リポジトリに Smokeping がありました。

With SmokePing you can measure latency and packet loss in your network. SmokePing uses RRDtool to maintain a longterm datastore and to draw pretty graphs giving up to the minute information on the state of each network connection.
インストールします。
apt -y install smokeping

Probe の設定
/etc/smokeping/config.d/Probes の内容を以下のように書き換えます。
*** Probes *** + FPing binary = /usr/bin/fping + DNS binary = /usr/bin/dig lookup = example.com pings = 5 step = 180 + Curl binary = /usr/bin/curl step = 60 urlformat = https://%host%/
Targets の設定
/etc/smokeping/config.d/Targets の内容を以下のように書き換えます。
*** Targets *** probe = FPing menu = Top title = Network Latency Grapher + ICMP probe = FPing menu = ICMP title = ICMP ++ Google_1_ICMP menu = 8.8.8.8 title = 8.8.8.8 host = 8.8.8.8 ++ Google_2_ICMP menu = 8.8.4.4 title = 8.8.4.4 host = 8.8.4.4 ++ Cloudflare_1_ICMP menu = 1.1.1.1 title = 1.1.1.1 host = 1.1.1.1 ++ Cloudflare_2_ICMP menu = 1.0.0.1 title = 1.0.0.1 host = 1.0.0.1 + DNS probe = DNS menu = DNS title = DNS ++ Google_1_DNS menu = 8.8.8.8 title = 8.8.8.8 host = 8.8.8.8 ++ Google_2_DNS menu = 8.8.4.4 title = 8.8.4.4 host = 8.8.4.4 ++ Cloudflare_1_DNS menu = 1.1.1.1 title = 1.1.1.1 host = 1.1.1.1 ++ Cloudflare_2_DNS menu = 1.0.0.1 title = 1.0.0.1 host = 1.0.0.1 + HTTP probe = Curl menu = HTTP title = HTTP ++ Google_HTTP menu = Google title = www.google.co.jp host = www.google.co.jp ++ Yahoo_HTTP menu = Yahoo! title = www.yahoo.co.jp host = www.yahoo.co.jp
Smokeping にアクセスする
http://xx.xx.xx.xx/cgi-bin/smokeping.cgi へアクセスすると Smokepoing が表示されるはずです。 時間の経過と共にモニタした結果がグラフ化されていきます。
