Host Resources Subagent
The Host Resources Subagent supports all the mandatory and two of the optional
groups of the standard Host Resources MIB. It also implements several groups defined
by HP that maintain information about hardware resources that might require operator
attention. These MIB extensions also let you manage the subagent and control the MIB
values it maintains. This section describes the Host Resources Subagent and its MIB.
Architectural Overview
The Host Resources Subagent facilitates management of system resources in several
ways:
•
Its MIB implements five of the MIB groups defined in RFC 1514, Host Resources
MIB . These groups describe hardware and software resources on the NonStop
system where the subagent is installed.
•
Several groups defined by HP extend the standard Host Resources MIB definition
to support proactive hardware management.
•
Other additional groups defined by HP support management of the subagent and
control over the objects it maintains in its MIB.
The Host Resources Subagent can be configured to monitor both NonStop Kernel
Guardian and Open System Services (OSS) personalities.
The remainder of this subsection provides more information about the features of the
Host Resources Subagent.
Standard MIB Groups

1514,

hrSystem group This mandatory group describes general host
