Performance Agent

The Performance Agent supports the Performance Manager by gathering, managing, classifying, and archiving OpenVMS system data, and providing the following functions:

• Data collection and storage
• Data archiving
• Dump reports
• Disk analysis
• PC sampling
• Real-time file activity display

The Performance Manager analyzes the collected data to produce a report that helps the system manager monitor system activities and make performance evaluations by identifying performance problems quickly. This report also identifies potential bottlenecks, including the specific device on which the bottleneck occurs.

The Performance Manager provides a facility to convert the data collected in the Performance Manager database into graphs. These pictures of system performance metrics are a robust source of information that enables a system manager to gain a better understanding of resource utilization and overall workload demands. By defining families of workloads with the Performance Agent's parameter editor, the graphs can represent site-specific user groups.

Performance Agent supports the Performance Manager with the following features:

• Provides support for stand-alone OpenVMS systems as well as clusters
• Allows automatic collection of system performance data easily defined by the user
• Archives data for presentation of any length of time in both report and graph format
• Groups users into workloads and families of workloads to allow for the reporting and modeling of system resources in terms of departments, projects, or any site-specific need
• Collects and reports system program counter data to analyze CPU activity
• Collects and reports disk space use
• Displays file activity on a disk
