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.

Fast performance problem solutions for z/VM and Linux for System z

On the VM and Linux mailing lists, a common question is asked: "My Linux is running slow, why?" This is like asking a garage mechanic why your car stopped, or telling a doctor "it hurts" without defining "it". There are several issues to be overcome in tuning Linux on System z. The first is the ability to detect problems; next is the ability to understand the problem; and third is the abilty to derive a solution.

Velocity Software provides zTune to help with all three of these issues. zTUNE is a feature of all Velocity Software performance products, and includes the services of the world's leading performance experts at Velocity Software. The zTUNE feature is the result of 15 years of solving VM and Linux on System z performance problems.

zTUNE can be installed on any z/VM system, where it will quickly diagnose over 100 different problems and, in most cases, give recommendations on how to correct them. This is even better than having a high- priced expert on site at all times, because as problems are discovered at other installations, new diagnostics will be added. Thus you receive the benefits of knowledge gleaned installations that were there before you. Check it out...

zTUNE is a subscription service provided by Velocity Software to quickly resolve your z/VM and Linux on System z performance problems. zTUNE identifies problems in z/VM and Linux on System z running under z/VM, and provides corrective recommendations when possible. When zTUNE cannot identify the problem, the world's leading performance experts are ready to solve your problems for no extra charge.

zTUNE requires a subscription license, and the lease and installation of Velocity Software's performance tools (ZVPS). Pay one annual fee and have performance analysis services available whenever you need them!

zTUNE Linux on System z Prerequisites

zTUNE can detect many zLINUX problems as well. For this added support, one of ZMON, or ZVPS is required. zMON is not a candidate for this support.

Net-SNMP must be installed and active on all Linux on System z nodes being serviced.
