Preface

Performance Manager is a real-time performance manager that provides tools for detecting and correcting performance problems from a central location. Performance Manager has a graphical user interface, or GUI, called pmgr that runs locally and can display data from your Compaq Tru64 UNIX (formerly known as DIGITAL UNIX) system.

With Performance Manager, you can monitor the state of a system or cluster in real-time. Tables and graphs, such as plot, area, bar, stack, stack bar, and pie charts, show you hundreds of different system values, including:

  • CPU performance
  • Memory usage
  • Disk transfers
  • File-system capacity
  • Network efficiency
  • AdvFS-specific metrics
  • Cluster-specific metrics

Performance Manager is an optional subset of Tru64 UNIX. Use this tool to monitor the performance of your workstation or server. PM monitors clusters using the cluster information block.

PM does not require a separate license. Previous versions of PM offered a distributed monitoring capability that required a separate license, but this fuctionality and related license have been retired.

Performance Manager for Tru64 UNIX® comprises two primary components: Performance Manager GUI (pmgr), and Performance Manager daemon (pmgrd). Additional daemons are used in monitoring TruClusterTM (clu_mib) and the Advanced File System (advsfd), supplied in the AdvFS Utilities subset.

Structure of This Document

This manual is organized as follows:

  • Chapter 1, Overview, provides a general description of Performance Manager's purpose and capabilities.
  • Chapter 2, Getting Started, describes setting up the environment, learning the terminology, and using the interface.
  • Chapter 3, Managing Nodes, describes using Performance Manager to manage and monitor the nodes in your network.
  • Chapter 4, Displaying Clusters, describes how Performance Manager displays clusters using auto-discovery
  • Chapter 5, Monitoring, describes creating, saving, and recalling sessions for monitoring data in real time, and customizing displays.
  • Chapter 6, Metrics, describes arranging your metrics in categories, and choosing which metrics to display or hide.
