*macOS High SierraにMRTGを設定 [#ja1f1f27]

**はじめに [#ee80b8ea]

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 [#af8e3153]

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 ✔

 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 [#tc72761d]

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🆑

**MRTGを実行する [#n7020835]

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．

$ mrtg mrtg.cfg🆑
 -----------------------------------------------------------------------
 ERROR: Mrtg will most likely not work properly when the environment
        variable LANG is set to UTF-8. Please run mrtg in an environment
        where this is not the case. Try the following command to start:

env LANG=C /usr/local/bin/mrtg mrtg.cfg🈁
 -----------------------------------------------------------------------
 $

環境変数がCである必要がある．
　指定して３回実行．

$ mrtg mrtg.cfg🆑

 $

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 [#f79b6484]

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．

$ cp -p /usr/local/bin/mrtg /usr/local/bin/mrtg.v00🆑
 $ diff /usr/local/bin/mrtg.v00 /usr/local/bin/mrtg🆑
 305c305
 <             import Socket6;
 ---
 >             Socket6->import(qw(inet_pton getaddrinfo));🈁
 $

もう１つ．

$ cp -p /usr/local/Cellar/mrtg/2.17.7/lib/mrtg2/SNMP_Session.pm /usr/local/Cellar/mrtg/2.17.7/lib/mrtg2/SNMP_Session.pm.v00🆑

 <         Socket6->import(qw(pack_sockaddr_in6 inet_pton getaddrinfo));
 ---
 > 	Socket6->import(qw(inet_pton getaddrinfo));🈁
 $

再度実行してみる．

$ mrtg mrtg.cfg

エラーは出なかった．ファイルを確認．
