VPAC/VM

A performance, accounting and control system for z/VM.

Key features

Online system performance monitoring

VPAC/VM can be accessed from any authorized CMS machine to obtain dynamic online displays of current or historical resource usage; extensive displays are available to monitor resources, such as I/O usage and individual users

Exception condition reporting

Thresholds for system and user resources can be set and exception messages produced to alert systems administrators to problems without the need for continuous monitoring; exception monitoring can be enabled and disabled selectively

Resource control

Thresholds can be applied to individual users and groups of users at specific times; when a threshold is exceeded, VPAC/VM will automatically take appropriate action, such as sending a warning message, forcing users off the system or preventing them from logging on at peak times

Resource usage accounting

VPAC/VM produces a number of standard reports to reflect user and system resource usage, accounting for all major resources on selected devices; you can also extract data to create your own reports
