7.8.4 CSVファイルの出力

dlmperfinfoユティリティに-fパラメタを指定すると，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パラメタに「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

注意事項

-cパラメタに「0」を指定した場合，ユーザがユティリティの実行を中止しないかぎり，連続実行します。ユティリティを終了するには［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パラメタに「0」を指定した場合

-aパラメタを指定した場合
1025バイト×（（パス数+1）×-mパラメタで指定する値+1）×-rパラメタで指定する値（バイト）

-aパラメタを指定しない場合
671バイト×（（パス数+1）×-mパラメタで指定する値+1）×-rパラメタで指定する値（バイト）

-cパラメタに「0」以外を指定した場合

-aパラメタを指定した場合
1025バイト×（（パス数+1）×-cパラメタで指定する値+1）（バイト）

-aパラメタを指定しない場合
671バイト×（（パス数+1）×-cパラメタで指定する値+1）（バイト）

（例1）パス数が3060の環境で，-aパラメタを指定して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パラメタを指定して，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パラメタは，60分×24時間=1440，-rパラメタは，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パラメタを指定して，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パラメタの値=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パラメタに「0」を指定した場合
（パス数+1）×-mパラメタで指定する値+1
ただし，ヘッダー部分を表示しないように-tパラメタ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パラメタで指定する値

-cパラメタに「0」以外を指定した場合
（パス数+1）×-cパラメタで指定する値+1
ただし，ヘッダー部分を表示しないように-tパラメタ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パラメタで指定する値

（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。
