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.

Performance and Capacity Planning
for z/VM and Linux on System z, zVSE, z/OS, distributed servers and more.

Velocity Software offers performance and capacity planning software, providing products, support and education to meet operational requirements of installations operating z/VM and Linux under z/VM. In 2020, we have added more for zVSE, a z/OS component, docker instrumentation, and support for MongoDB.

Our products are developed, maintained, and supported by experts in performance and capacity planning. Education is provided by the worlds leading experts. We keep the VM and Linux communities up-to-date with performance tuning techiques, training, and technical tips through our Performance Newsletter.

The Velocity Software products are all completely integrated, with each new component being developed as part of the suite. None of the products are "add-ons", with interfaces subject to failure. With Operations, Alerts, and Performance management all integrated, moving from one function to another is seemless. Installations have the ability to "click through" from one function to another as needed.

zVWS, the native z/VM webserver provided by Velocity Software is FAST. This website and many others are hosted using zVWS. Many of our applications such as zVIEW and zPRO are only possible because of having a very fast native webserver. Our brochures for zVPS loads very quickly....

Full data collection capabilities (z/VM, Linux, Windows, Unix, Network)

z/VM systems are complex environments. Without complete and correct performance data, mysterious problems can occur. zVPS collects full performance data on the following:

Interfaces to other vendor products

Velocity Software works closely with other vendors to enable installations to best utilize their system with a minimum of product conflict.

Agentless Support for Other Platforms

Support for Linux and other platforms is Agentless! Using data collected only via snmp, there are no proprietary or resource intensive agents required for data collection. Microsoft servers and Solaris servers measurements can be seen on the Velocity Software demo site.

Real-time performance analysis

To meet service level requirements, performance problems must be solved quickly.

zVPS provides:

Full capacity planning

zVPS provides the necessary capacity planning tools for z/VM and Linux on System z systems. Capacity planning requires the following capabilities to allow utilization of all resources to be tracked:


Velocity Software provides performance education worldwide for the z/VM platform.

Velocity Software is the recognized leader — both in product capabilities and in experience — in measurement facilities for consolidation of servers such as Windows or Sun to Linux running under z/VM.
