macOS High SierraにMRTGを設定 
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) * Poured from bottle on 2019-05-07 at 00:48:32 From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/mrtg.rb ==> Dependencies Required: gd ✔ ==> Analytics install: 30 (30 days), 76 (90 days), 458 (365 days) install_on_request: 26 (30 days), 69 (90 days), 381 (365 days) build_error: 0 (30 days) $
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🆑 Subroutine SNMP_Session::pack_sockaddr_in6 redefined at /System/Library/Perl/5.18/Exporter.pm line 66. at /usr/local/bin/../lib/mrtg2/SNMP_Session.pm line 149.

これで問題ないと思う．
MRTGを実行する
mrtg.cfgファイルを読み込ませながら，mrtgコマンドを実行する．

３回実行する理由は，初回はファイルが無いのでエラーがでるのだが，ここでは別のエラーがでている．．．
SNMP_Session.pm line 149,SNMP_Session.pm line 604に
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．

ファイルができていることが確認できた．
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．
$ locate indexmaker🆑 /usr/local/Cellar/mrtg/2.17.7/bin/indexmaker /usr/local/Cellar/mrtg/2.17.7/share/doc/mrtg2/indexmaker.1 /usr/local/Cellar/mrtg/2.17.7/share/doc/mrtg2/indexmaker.pod /usr/local/Cellar/mrtg/2.17.7/share/doc/mrtg2/indexmaker.txt /usr/local/Cellar/mrtg/2.17.7/share/man/man1/indexmaker.1 /usr/local/bin/indexmaker /usr/local/share/man/man1/indexmaker.1 $
コマンドヘルプを確認．
$ /usr/local/bin/indexmaker -h🆑
Option h is ambiguous (headeradd, headeradd-file, headlevel, height, help)

--pagetop=text insert this text between <BODY> and <H1>...</H1>
--pageend=text insert this text after the main body
--pagetopend=text use this text for pagetop or pageend if undefined
--nolegend do not add the Mrtg legend at the end of the page
--columns=number show graphs in a table with x columns (default: 2)
--perhost show graphs of the same host on a row
--compact try to make a vertically more compact page
--optlog log the used command line in the page (default: log)
--sort=title sort graphs by title
--sort=name sort graphs by their name
--sort=descr sort graphs by their description
--sort=original leave as is (default)

vi /usr/bin/mrtgで開いて，次のように書き換える．
変更前：import Socket6 変更後：Socket6->import(qw(inet_pton getaddrinfo));
次に，vi /usr/local/bin/../lib/mrtg2/SNMP_Session.pm で
変更前：if (eval {local $SIG{__DIE__};require Socket6;} &&
変更後：if (eval {local $SIG{__DIE__};Socket6->import(qw(inet_pton getaddrinfo));} &&原因は，Perlのバージョンアップとのこと．
