SM2 operation

In addition to report output at the terminal and on the printer, consecutive output of
monitored data to the SM2 output file is provided for.

At file creation time, a system task is generated for writing to the SM2 output file. This
system task terminates when the SM2 output file is closed.

Use of the SM2 output file is recommended

–

when system utilization is to be monitored for an extended period of time (standard
case, trend monitoring)

–

for bottleneck analysis (peak load analysis) if special monitored data is required in
addition to the global system monitored data. The corresponding monitoring programs
must be activated for this purpose.

Only the SM2 administrator can create and close the SM2 output file.

The file attributes are preset by SM2, but the SM2 administrator can change the preset
default options.

The SM2R1 analysis routine converts the monitored data to bar charts and/or tables with
statistical data before output.

The SM2R1 data interface (SM2R1 transfer file) is available to users who wish to analyze
monitored data using their own programs. For information on the record structure of this file,
see the chapter “SM2R1 analysis routine” in Volume 2 of the SM2 manual [21]).

The SM2 administrator can choose to create an SM2 output file with the preset file attributes
or to open an SM2 output file with freely selected attributes.

This file is opened with the statement OPEN-LOG-FILE FILE=*STD. SM2 opens a SAM file
in output mode and catalogs it under the name SM2.hostname.yyyy-mm-dd.sss.nn.

Here, hostname indicates the assignment to a host, yyyy.mm.dd is the date on which the
file was created, sss is the number of the BS2000 session and nn is the consecutive number
of the SM2 output file within that session (counted from 1).
