Revision/Update Information:

Preface

Performance Manager is an SNMP-based, user-extensible, real-time performance monitoring and management tool that allows you to detect and correct 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 the managed nodes in your Tru64 UNIX network. Performance Manager operates through interaction between nodes assigned as management stations and managed nodes.

It is possible for a managed node to also be the management station. For more information on management stations and managed nodes, read the Overview.

For updates and the latest information about Performance Manager, see the PM Web Site at this URL: http://www.unix.digital.com/unix/sysman/perf_mgr/

Performance Manager is an optional subset of Tru64 UNIX but requires a license for use in a distributed fashion. Without the license, this product acts only on the node running the graphical user interface (GUI). With the distributed license, it can act on any number of nodes in your network.

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 ( clstrmond) and the Advanced File System (advsfd ), supplied in the AdvFS Utilities subset.
