【インストール方法】
１．MRTGを解凍してC:\にmrtg新規フォルダを作成してc:\mrtgフォルダに本体を保存する。
２．ローカルマシンのMRTGの設定ファイル（mrtg.cfg）を自動生成する場合はDOS窓で下記コマンドを実行すればC:\mrtg\binにmrtg.cfgが作成される。
例）
・SNMPコミュニティー名 ： public
・mrtg.cfgで作成されるWEBファイル設置場所 ： C:\xampplite\htdocs\mrtgdata
・MRTGの設定ファイル名 ： mrtg.cfg
C:\>cd C:\mrtg\bin
C:\mrtg\bin>perl cfgmaker public@localhost –global “WorkDir: C:\xampplite\htdocs\mrtgdata” –output mrtg.cfg
上記のコマンドを実行するとＤＯＳ窓には、下記のような表示されC:\mrtg\binにmrtg.cfgが作成されます。
cs\mrtgdata” –output mrtg.cfg

–base: Writing mrtg.cfg
（参考：作成されたmrtg.cnfの一番下の行に展開するフォルダーが記載されているので変更することにより別の場所にMRTGファイルを展開する事が可能である。）
WorkDir: C:\xampplite\htdocs\mrtgdata
３．DOS窓から下記コマンドを実行すると指定されたフォルダーにhtmlファイルが作成される。
C:\cd \mrtg\bin
C:\mrtg\bin>perl mrtg mrtg.cfg
４．上記コマンドを定期的（５分間１回）に実行すると、そのデータが蓄積され下記の様なＵＲＬでＭＲＴＧグラフが表示さる。
（C:\xampplite\htdocs\mrtgdataのフォルダの中身を見て拡張子htmlが付いているファイルを指定下さい。）
(例）
http://localhost/mrtgdata/localhost_1.html
５．DOS窓より perl mrtg mrtg.cfg のコマンドを定期的に実行してあげる必要があり、UNIXだとcron等で対応できるようですがWindowsでは、使用できないためタスクスケジューラを利用する事にします。
