Performance Toolkit for VM Feature FL710

Performance Toolkit for VM provides enhanced capabilities for a z/VM systems programmer, system operator, or performance analyst to monitor and report performance data. Offered as a priced optional feature of z/VM, Performance Toolkit for VM is derived from the FCON/ESA program (5788-LGA), which was not available in some countries.

Use Performance Toolkit to reduce data from the z/VM monitor and produce reports and history files.
