7.7.4　CSVファイルの出力

dlmperfinfoユーティリティーに-fパラメーターを指定すると，指定したファイル^※に性能情報を出力します。項目名と値は，それぞれ「"」（引用符）で囲まれ，コンマ区切りで出力されます（CSV形式）。出力する内容は「表7‒5　出力内容一覧」を参照してください。

注※

-cパラメーターに「0」を指定した場合は，指定したCSVファイル名の後に_YYYYMMDDhhmmss.csvが付いたファイルに出力されます。YYYYMMDDhhmmssは，ファイルを作成した日時（協定世界時）です。

CSVファイルの出力例を次に示します。

実行例

# /usr/DynamicLinkManager/bin/dlmperfinfo -i 300 -c 2 -f CSVファイル名

注意事項

• -cパラメーターに「0」を指定した場合，ユーザーがユーティリティーの実行を中止しないかぎり，連続実行します。ユーティリティーを終了するには［Ctrl］+［C］で処理を中止してください。

• CSVファイルを出力する場合は，ファイル出力先のディスクを圧迫しないように，次の計算式で必要なディスク容量を計算してください。また，不要になったCSVファイルは適宜削除するようにしてください。

  • -cパラメーターに「0」を指定した場合

    • -aパラメーターを指定した場合

      1025バイト×（（パス数+1）×-mパラメーターで指定する値+1）×-rパラメーターで指定する値（バイト）

    • -aパラメーターを指定しない場合

      671バイト×（（パス数+1）×-mパラメーターで指定する値+1）×-rパラメーターで指定する値（バイト）

  • -cパラメーターに「0」以外を指定した場合

    • -aパラメーターを指定した場合

      1025バイト×（（パス数+1）×-cパラメーターで指定する値+1）（バイト）

    • -aパラメーターを指定しない場合

      671バイト×（（パス数+1）×-cパラメーターで指定する値+1）（バイト）

  （例1）パス数が3060の環境で，-aパラメーターを指定して288回収集する場合

  dlmperfinfo -c 288 -f CSVファイル名 -aを実行する場合で，ファイルサイズは次のとおりです。

  1025×（（3060+1）×288+1）=903608225（バイト）（約862MB）

  （例2）パス数が500の環境で，-aパラメーターを指定して，1分の時間間隔で1日分を1ファイルとして，1年間分のファイルを収集する場合

  -mパラメーターは，60分×24時間=1440，-rパラメーターは，1年の日数+1=366 なので，dlmperfinfo -i 60 -c 0 -f CSVファイル名 -m 1440 -r 366 -aを実行する場合で，ファイルサイズは次のとおりです。

  1025×（500+1）×（1440+1）×366=270836166150（バイト）（約252.2GB）

  （例3）パス数が1000の環境で，-aパラメーターを指定して，ファイルあたりの測定回数を1440として，ファイル容量を2TB以内にする場合

  -rパラメーターの値=2×1024⁴÷（1025×1001×1441）≒1487.3（ファイル）

  そのため，ファイル容量を2TB以内にするには1487ファイルまで作成できるので，dlmperfinfo -c 0 -f CSVファイル名 -m 1440 -r 1487 -aを実行できます。

• CSV出力ファイルの行数は次の計算で求められます。次の計算式で1ファイル当たりの出力行数を算出し，測定回数を調整してください。

  • -cパラメーターに「0」を指定した場合

    （パス数+1）×-mパラメーターで指定する値+1

    ただし，ヘッダー部分を表示しないように-tパラメーターを指定して実行した場合は，次のようになります。

    パス数×-mパラメーターで指定する値

  • -cパラメーターに「0」以外を指定した場合

    （パス数+1）×-cパラメーターで指定する値+1

    ただし，ヘッダー部分を表示しないように-tパラメーターを指定して実行した場合は，次のようになります。

    パス数×-cパラメーターで指定する値

  （例1）パス数が500の環境で，ヘッダー部分を表示しないで1ファイルに500回分測定結果を出力する場合の行数

  （500+0）×500+0=250000（行）

  （例2）パス数が1000の環境で，ヘッダー部分も表示して1048576行までに抑える測定回数

  （1048576-1）÷（1000+1）≒1047.5（回）

  そのため，1ファイルに1047回まで測定結果を出力できます。
