Logwatch導入でサーバの状態を定期チェックするよ!+ Evernoteも!

スポンサードリンク

といっても、ログをメールしてくれるだけで、それをチェックしないと全く意味ないですけどね。今回は、Logwatch をインストールしてさらに、その結果を Evernote のノートとしてに自動的に反映させてみたいと思います。Evernote はよくいじるので定期的にチェックするはず。。。

次のページが参考になりました。ありがとうございます。

ちなみに、本家サイトのLogwatch – Browse Files at SourceForge.netはあまり参考にならなかったです。残念です。

設定。ここで Evernote に自動的にノートされるようにします。

デフォルト設定からの変更点を次のファイルに記述していきます。今回のポイントである、Evernote のノートとして自動的に反映させるためには「ノートのメール先」をメール送信先に設定します。これだけです。簡単ですね。なお、「ノートのメール先」は次の方法で確認できます。

【デスクトップ版】

  • ソフトを立ち上げ、上部にある使用量 > アカウント情報ウィンドウが開く > ノートのメール先
では実際に編集していきます。ちなみに、設定のメールアドレスはダミーですのであしからず。
vim /etc/logwatch/conf/logwatch.conf
# Local configuration options go here (defaults are in /usr/share/logwatch/default.conf/logwatch.conf)

# Local configuration options go here (defaults are in /usr/share/logwatch/default.conf/logwatch.conf)
MailTo = XXXXXX.9999x@m.evernote.com

覚えておいたほうがよいことまとめ

  • LogWatch の設定ファイル
    /usr/share/logwatch/default.conf/logwatch.conf
  • LogWatch の実行スクリプト(配信テストができる)
    /usr/share/logwatch/scripts/logwatch.pl
  • LogWatch テスト。コマンドライン上にメールで送る内容を表示する。–range all  ですべての内容を表示させる。
    /usr/share/logwatch/scripts/logwatch.pl –range all –print
  • Logwatch を一日一回行うシンボリックリンク
    /etc/cron.daily/0logwatch

    ll /etc/cron.daily/
    合計 20
    lrwxrwxrwx 1 root root  39  2月 27 23:31 0logwatch -> /usr/share/logwatch/scripts/logwatch.pl
    ・・・略・・・

    ※ /etc/cron.daily 以下に Logwatch を一日一回行うシンボリックリンクが出来ます(メール配信時間を変更したい場合は /etc/crontab を編集するらしいです)。

テスト

  1. 全ログをコマンドラインに表示してみます。
  2. ログメールを送信してみます。

1.全ログをコマンドラインに表示してみます。

/usr/share/logwatch/scripts/logwatch.pl --range all --print
