Velocity Software, Inc. is recognized as a leader in the performance measurement of z/VM and Linux on z. The Velocity Performance Suite consist of a set of tools that enable installations running z/VM to manage Linux and z/VM performance. In addition, many components of server farms can be measured and analyzed. Performance data can be viewed real-time through the use of either 3270 or a browser. The CLOUD Implementation (zPRO) component is designed for full cloud PaaS implementation as well as to extend the capabilities of the z/VM sysprog (system programmer) to the browser world. This feature moves system management to the point-and-click crowd. Archived data and reports can be kept available of long term review and reporting usine zMAP. The zVPS, formally ESALPS, components consist of: zMON (formally ESAMON - real-time display of performance data), zTCP (formally ESATCP - SNMP data collection), zMAP (formally ESAMAP - historical reporting and archiving), zVWS (formally ESAWEB - z/VM based web server), zTUNE (a subscription service), zVIEW (formally SHOWCASE - web based viewing of performance data), zPRO (new to the quality line of Velocity Software Products). Velocity continues to work with other software vendors to ensure smooth interface with or from other products such as VM:Webgateway, CA-Webgateway, EnterpriseWeb, MXG, MICS. Velocity software remains the leader and inovator in the z/VM performance, Linux performance, Managing cloud computing arenas.

Accounting for z/VM Servers

At the z/VM level, installations will want to provide accounting by

The database extracts are very simple and look like the following, extracting by user, the account number, cpu consumed, pages resident, and virtual I/O. Users only in the *Linux class are extracted, and only during prime shift.

 
EXTRACT:            ; First extract system data
 
columns ='10 10 10 10 7 8 8 8'
TITLE = 'STARTTIME  STOPTIME  USERID    ACCTNBR      CPU   Pages'
TITLEc= '      VIO'
TITLE = '---------- --------- --------- -------- -------  ------'
TITLEc= ' --------'
 
X = 'STARTTIME'
Y = 'STOPTIME'
Y = 'USERID'
Y = 'USRCON.VMDACTNO'
Y = 'USEACT.VMDTTIME' ; cpu utilization
Y = 'USEACT.VMDCTPVR / 256' ; MB Resident
Y = 'USEACT.VMDVDSCT' ; VIO
 
INTERVAL='SU'
CRITERIA='USRTYPE=USER'
CRITERIA='USRCON.CLASSID=*Linux'
CRITERIA='STARTTIME >= 080000'
CRITERIA='STOPTIME <= 170000'

The results of this extract then would look like the following showing hourly consumption by linux server. This would be input into installation accounting procedures.

 
Date    Time     STARTTIME  STOPTIME    USERID     CPU   Pages     VIO
