Raspberry Pi に Smokeping をインストールしてスループットをモニタする

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。

Description: latency logging and graphing system
 SmokePing consists of a daemon process which organizes the
 latency measurements and a CGI which presents the graphs.
 .
 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

Apache で CGI を有効化しておきます。

a2enmod cgi

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

+ HTTP

probe = Curl
menu  = HTTP

++ Google_HTTP

menu  = Google

++ Yahoo_HTTP

menu  = Yahoo!

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。
