Proactive Hardware Management; Refreshing Mib Values - HP T9576G06 Management Manual

Host Resources Subagent
The group and trap definitions, identified by a check mark in the following list, reside in
the zhrm subtree within the subtree registered to HP:
iso (1)
identified-organization (3)
dod (6)
internet (1)
private (4)

Proactive Hardware Management

You can configure the Host Resources Subagent to generate traps that describe
situations that might require system operator intervention. For example:
A particular device is no longer running.
A particular disk is demonstrating critically high usage.
A particular CPU is demonstrating critically high RAM usage.
Entries maintained in several MIB groups also support proactive management of
hardware resources:
The zhrmThreshold group provides information on device utilization that exceeds a
settable threshold.
The zhrmDevUnavail group provides device statistics and highlights unusual
device states.

Refreshing MIB Values

MIB values are always refreshed when a subagent process starts. After startup, to
control its CPU usage, the subagent uses two configurable timers for refreshing MIB
values:
A stable object timer controls the rate at which hardware configuration information
is refreshed. Configuration information is relatively static, changing mainly when
devices are added to or removed from the system.
