Zabbix 2.2.1で各アイテムの値をデータとして取得するときは、
「監視データ」－＞「最新データ」－＞「グラフ」or「ヒストリ」から「値」を選択すると
「プレーンテキスト」ボタンでTSV形式で取得できるようですが、なぜか1000個ぐらいまでしか
取得できませんでした。（1分ごとの取得するアイテムだと16.6時間分しか取得できない）
しょうがないので、mysqlのDBにから直接情報ｗ取得出来ないかを調べてみました。
本来は、Zabbix API使うのが正当なんだろうけど、現状うまく使いこなせません。
まずはmysqlの使い方を確認
mysqlクライアントで実行（表形式で出力されます）
# mysql zabbix > (ここにSQLを入力。最後に;)
直接SQL分を指定して実行するには、以下のように指定します。
直接SQL分を記述 # mysql zabbix -e "(SQL文)" SQLを記述したファイルを指定して実行 # mysql zabbix -e "`cat outcsv.sql`"
ファイルにｔｓｖ出力するには、単純に標準出力をリダイレクトすればよいようです。
# mysql zabbix -e "(SQL文)" > /tmp/test2.tsv 例 # mysql zabbix -e "select h.host, h.name, i.name, i.description, i.key_ from items i join hosts h on h.hostid = i.hostid where h.name = 'N54L' order by i.key_ " > /tmp/test2.tsv
ファイルにcsv出力するには、以下のようにtabを’,’に変換して出力します。
# mysql zabbix -e "(SQL文)" | sed -e 's/\t/,/g' > test.csv
実際に、Zabbix 2.2.1のDBから情報を取得してみます。

こんな感じにすれば、情報は取得できそうですが、
Zabbix のバージョンが上がった時に対応できなくなる可能性が高いのが残念。
あと、mysqlの設定が標準だと検索に時間がかかります。
実際にはチューニング必須なようです（チューニング方法はまた今度）
