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.
