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.

Managing IBM Secure Container (and Docker containers)

Many IBM presentations on IBM Secure Container have left the impression that this was a black box - "Black box" meaning that if there was a performance problem or a lack of resource or other things that could impact the workload, there was no mechanism for diagnosing the problem. Customers rarely want to trust important workload to a black box - as jobs are at risk when applications fail to meet requirements due to bad architectural decisions.

Velocity Software, in conjunction with the IBM Secure Container team, have developed an architecture and solution to this problem. The architecture of the IBM Secure Container does not allow for bi-directional requests as zVPS does to support Linux using snmp. However, an open source package, collectd, can be installed and tailored to send data to an IP address using the UDP protocol. zVPS has been enhanced to support this data feed, and now provides full performance management for IBM Secure Container using the collectd open source package.

zVPS will provide operational alerts, historical data, capacity planning information, and performance diagnostic capability to the IBM Secure Container using this architecture.

Installations wishing to test this function may actually point their collectd collector at the Velocity Software cloud and see their data - send a note to Barton if interested, and the correct IP address and port will be provided for your testing.

The collectd package is also useful for monitoring other docker container architectures as well. This is in addition to the docker mib as currently provided by Velocity Software.

The following examples show some of the data provided by collectd and some of the reporting provided by zVPS, the Velocity Software Performance Suite:
