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.

zOSMON ™, by Velocity Software, Inc.

Velocity Software has added z/OS to its performance management suite. As the industry leader in z/VM performance management for over 30 years, and as the industry leader in Linux on IBM Z performance management for almost 20 years, many zVPS installations have requested support of z/OS metrics in our modern and flexible graphical interface.

zOSMON has many benefits that should appeal to everyone from the performance specialist to the mainframe management executives.

zOSMON currently fully exploits the SMF records 30, 70, and 110. With the ability to collect data from all the z/OS LPARs in an enterprise, there is one centralized database for the enterprise. With such a low cost of operation, data can be processed in multiple locations for full redundancy.

zOSMON Version 1 is generally available. If you would like to evaluate zOSMON, send us an email to

Performance management overhead

Many existing performance management solutions consumes significant amounts of resource. At some point, offloading to a zIIP seems to reduce the overall cost - but the cost of data analysis in Java is really the problem. Providing full analysis for the SMF records in low level languages with regard to cost is a better approach. There are two parts of the resource equation, the agent on z/OS and the z/VM zVPS component.
