はじめに
- MRTGとは，マルチルータトラフィックグラファーの略．ルータのIN/OUTトラフィックをグラフ化するツールで，古典的なも
の．たくさんのサーバを管理するにはZabbixなどが良いのだろうけれど，今回もシンプルに構築するので，MRTGを選んだ．
インストール
- インストールはHomeBrewでおこなった．特に問題もなかった．
$ brew info mrtg🆑
mrtg: stable 2.17.7 (bottled)🈁
Multi router traffic grapher
https://oss.oetiker.ch/mrtg/
/usr/local/Cellar/mrtg/2.17.7 (110 files, 2.4MB) *

$
- インストールされたか，コマンドの場所を確認．
- まずは，mrtgコマンド．
$ which mrtg🆑
/usr/local/bin/mrtg🈁
$
- そして，設定ファイルを自動的に作成してくれる，cfgmakerの場所を確認．
$ which cfgmaker🆑
/usr/local/bin/cfgmaker🈁
$
初期設定
- まずは，SNMPD.CONFにあるコミュニティ名を確認．
$ grep com2sec /etc/snmp/snmpd.conf🆑
com2sec local localhost private🈁
com2sec mynetwork NETWORK/24 public
$
- "private"だとわかった．
- cfgmakerコマンドを指定し，privateコミュニティの初期設定を行う．
$ cfgmaker private@localhost > mrtg.cfg🆑

- このエラーは，Perlのバージョンが新しい場合に出る模様．
- コードを書き換えれば修正される．次のように．バックアップを取った後に修正する．

HTMLファイルを作成
- MRTGのグラフをWebブラウザで参照するための，インデックスページを自動的に作成してくれる．
- これは最初に１回実行すれば良いが，定義を追加した際に，毎回実行すれば良い．
- インデックス作成用のindexmakerコマンドを探す．
