Performance Manager 2.0A and 2.1A User's Guide

Overview

Performance Manager interacts between nodes assigned as management stations and managed nodes. Their features are described in the following section.

Management Station

Management Stations are the operating centers for managing and monitoring the nodes in the system. With Performance Manager You can monitor the state of one or more managed nodes in real-time. Tables and graphs, such as plot, area, bar, stack bar, and pie charts, show you hundreds of different system values, including:

In addition to monitoring, Performance Manager provides these features for actively managing your network:

Managed Node

Managed nodes are those that run one or more metrics servers recognized by Performance Manager. A metric server is a daemon process that implements management information base (MIB) variables that the Performance Manager GUI knows about.

A metrics server listens for and services requests for operating system metric information. These requests are issued by management applications such as the Performance Manager GUI. Upon receipt of such a request, a metrics server queries the operating system and returns the appropriate value(s) to the requester. The following are examples of metrics servers supported by Performance Manager:

The pmgrd and clstrmond metrics servers are provided with Performance Manager. Other metrics servers either come with the operating system (such as os_mibs) or are provided by other products (such as advfsd).

PM-provided metrics servers support SNMPv1 when used in conjuction with the Digital UNIX extensible SNMP agent (snmpd). In addition, they support extensions for bulk data transfer of metric data. Because metrics servers support SNMP, you can use other SNMP applications to access their data. In addition, a set of UNIX commands for command-line metrics server access is also provided.

The nodes and metrics you choose to monitor can be saved as a session, then played back or modified later.
