zMAP is a flexible software product that analyzes performance data and produces clear, detailed reports for performance analysis. zMAP is designed to efficiently store, retrieve, and report on monitor data for capacity planning and long-term performance trend analysis. It also provides "artificial intelligence" problem analysys and taking remedial action as appropriate. Velocity Software designed zMAP to produce a wide range of reports, providing insight into all aspects of z/VM, Linux, z/VSE, and z/OS performance. You can gather information on resource contention, consumption levels, transaction response times, enhanced MDC, user service levels — all presented in the clear format you need to manage, plan and control system resources. zMAP provides the most sophisticated, comprehensive reporting capabilities available.
The industry leader: Since 1988, zMAP has continued to gain market share as the most comprehensive z/VM performance monitor on the market. Being the industry leader means leading in all areas. If you have a performance problem, you need the leader, you need to have all the information available to you. Velocity Software is the solution.
As Velocity Software adds new monitoring capabilities, zMAP is also updated with new reports; z/VSE, z/OS, MongoDB, Docker, GPFS (Spectrum Scale), sub-capacity reporting and more.
Comprehensive Reporting: Over 100 different reports are provided, from high-level overviews to detailed subsystem reports. Complete system reporting includes our unique service level agreement (SLA) reporting, statistical summaries, full DASD cache analysis, SFS analysis, device analysis, minidisk cache usage, and seeks analysis. If there's something we're not reporting, we want to know!
As IBM continues to strengthen z/VM, Velocity Software continues to enhance zMAP.
Easy-to-use Reports: zMAP reports are presented in a natural and intuitive hierarchy, from management summaries to subsystem reports ideal for fine-tuning and capacity planning.
Service Level Agreements: zMAP's unique ability to provide transaction response based on percentiles is often used for written service level agreements. This is the only proven your user response time measurement technique that is consistent, accurate, and reflects user perception. The Service Level Agreement (SLA) facility measures actual user response time against management objectives, reported as both percentages and averages — the only such facility in a z/VM product.
Trend Analysis: zMAP's comprehensive historical reporting can process history files or raw monitor data for report creation and long-term trend analysis.
Performance Database: The performance database functions provided with zMAP include the ability to extract data, plot values, and create your custom reports using varied reporting tools.
Plotting Facility zMAP includes a general purpose, easy-to-use graphical plot facility for quick interactive plotting, as well as an extract program to transfer specific data from history files to PC graphics packages, SAS, VMPAF, et al.
Standard Interface: zMAP exploits monitor data generated by z/VM's Control Program. This allows the product to run under any version of z/VM, starting with VM/XA and continuing through the latest versions.
zMAP has no hooks into the operating system. It is fully upward-compatible, and older versions continue to run on new versions and releases of the z/VM operating system with absolutely no changes required. But that doesn't mean Velocity lets the product stagnate — constant improvements exploit the latest additions to z/VM, Linux, z/VSE, and z/OS monitoring capabilities, providing the most up-to-date analysis of any product.
The famous ESATUNE Report: Artificial intelligence provides tuning recommendations every time you run zMAP. The zTUNE report flags potential performance bottlenecks and provides recommended actions for remediation.
Low operation cost: zMAP provides extensive reporting about all z/VM subsystems, even DASD seeks analysis, without taxing your systems resources. zMAP runs many times faster than our competitors' historical monitors, and uses far fewer resources. Velocity Software's product architecture completely eliminates the requirement to collect and store raw monitor data. In tandem with our real-time monitor, zMON, this typically frees up 95% of the disk space currently dedicated to storing monitor data.
ESAVSW: Virtual Switch Report The ESAVSW report shows activity on virtual switches (VSWITCHes). VSWITCHes provide significant bandwidth improvements for Linux servers running under z/VM, as well as below-the-line storage contraint relief.
Linux Application Reporting Analyzing the hundreds of Linux processes typically active requires added data reduction to make the data usable. The ESAHSTA report groups processes by process name, allowing a view into where CPU is actually being used.
Linux Reporting Velocity Software has added significantly to the information extracted from Linux, including additional process data to help with more effective capacity planning and performance analysis. The ESALNXA (Application), ESALNXP (Process Statistics), and ESALNXS (System Statistics) are derived from this data. Other data items provided by NETSNMP as part of the UCD MIBs are corrected using the new Velocity Software function.
