MULTI PLATFORM VTS MONITORING
_____________________________


This  package  describes  a  Virtual Tape Server performance
analysis tool allowing extraction and  analysis  of  statis-
tical data directly from the 3494 Library Manager as well as
through  MVS  based  System Measurement Facility (SMF), thus
making it independent  of  the  platform  the  Virtual  Tape
Server is connected to.

Before this package, there were no ways to monitor a Virtual
Tape Server attached to VM only systems.

With  the  future  Open  Systems Attachments of Virtual Tape
Server, this tool should prove even more useful.

When entering the arena of critical situation, this tool can
be run exclusively on the Library Manager of  the  3494.  So
without  disturbing neither the customer nor the production,
this package can produce, in less than an hour,  a  complete
analysis of the workload of the last few days.

With Import/Export support (APAR OW36360), the SMF 94 record
layout  has changed. MVS users of this package must do a re-
fresh.  Other users are not impacted. The distributed  mate-
rial consists of:

1.  A ZIP-file called VTSLOGRP.ZIP (or VTSLOGRP.EXE)
2.  A readme text called $READLOG.TXT

To install the VTSLOGRP package, proceed as follows:

1.  Open  an  MS-DOS window or an OS/2 window and make a di-
    rectory named VTSPERF.

        C:
        C:md VTSPERF (enter)

2.  Access the Tape Analysis Tools
    (http://w3.rmss.tucson.ibm.com/software/tapetools.htm)
    or
    (External tools:  ftp://index.storsys.ibm.com/tapetool)

3.  Print $READLOG.TXT

4.  Download the VTSLOGRP.EXE (or VTSLOGRP.ZIP) on  your  PC
    into  the  VTSPERF directory you have just created, fol-
    lowing the instructions on the website.

5.  Go back to the previous window.

        C:
        C:cd VTSPERF (enter)
        C:‡VTSPERF>

6.  Now unzip the tool:

        C:‡VTSPERF>c:‡window‡utils‡pkunzip c:‡vtsperf‡vtslogrp.zip(enter)
        or
        C:‡VTSPERF>vtslogrp
        and then specify C:‡VTSPERF when prompted for a directory

    The exploded files will be:

        $READLOG.TXT
        The  download information and a brief description of
        the package. (this file).

        LOGSCAN.CMD
        The executable program to  extract  the  statistical
        data  from  the  Library  Manager and build the flat
        file. (to be run on the library Manager

        VTSLOGRP.PRZ
        A presentation in Freelance of the VTSLOGRP package.

        VTSLOGRP.CMD
        The data analysis program that produces the  reports
        on  the  VTS  workload.  (to be run on the LM or any
        other OS/2 or Windows or VM or MVS platform).

        VTSLOGRP.AFP
        This manual is in LIST3820 format and  contains  in-
        formation  on how to run the tool and create the re-
        ports.

        VTSLOGRP.UPD
        The MVS distribution of this  tool,  which  includes
        the  LOGSCAN  program,  the  JCL,  and procedures to
        produce the flat file on  MVS  and  to  execute  the
        VTSLOGRP program on MVS.

        VTSLOGRP.XMP
        A  sample of the output report. This sample includes
        the execution log file of the  VTSLOGRP  program  as
        well  as  the  HELP text and the hit parade reports;
        which are quite convenient   when selecting  a  spe-
        cific day to present with VTSGRAPH.
