Application Zoom on a Graph
If you zoom-by-application on a graph, application data is listed as
shown in the following table.
In a tabular window created from a graph, each column in the table lists
a separate data element. Table rows represent summary entries for each
application in every 5-minute sample period.
Not all data can be displayed at once in the tabular window. Use the
vertical and horizontal scroll bars to see additional rows and columns.
Application Data
The data elements in Table A-37 are presented when you
zoom-by-application on a graph. Column headings are listed in the order
that they appear (left to right) in the tabular window.

NOTE On MPE XL systems, there is a relatively high ratio of logical disc
I/O to physical disc I/O. In part this is due to MPE XL caching of
disc writes as well as reads. To a larger degree, it is due to a
definition of a logical I/O that is different than the one used on
MPE V systems.
Under MPE V, a logical I/O occurs when the file system makes a
request to the I/O system to transfer a block of data to or from a
disc file. Under MPE XL, a read attempt or write attempt occurs
whenever a program makes a request of the file system to transfer
data.
These transfers may occur at each record, at each block if
multi-record I/O is done), or not at all (if mapped files are
used). MPE XL read/write attempts are the closest metric to the
MPE V logical I/Os, but they are not equivalent.
