EMS Hardware Monitors: Overview

GUI.
Peripheral Status Monitor (PSM)
Included with the hardware event monitors, the PSM is a monitor daemon that acts as a hardware
status monitor by converting events to changes in hardware resource status. This provides
compatibility with MC/ServiceGuard, which uses changes in status to manage cluster resources. The
PSM is also used to create hardware status monitoring requests through the EMS GUI.
polling
The process of connecting to a hardware resource at regular intervals to determine its status. Any
events that occur between polling intervals will not be detected until the next poll, unless the
monitor supports asynchronous event monitoring.
resource instance
A specific hardware device. The resource instance is the last element of the resource path and is
typically the hardware path to the resource (e.g., 10_12_5.0.0), but it may also be a product ID as in
the case of AutoRAID disk arrays. There may be multiple instances for a monitor, each one
representing a unique hardware device for which the monitor is responsible.
resource path
Hardware event monitors are organized into classes (and subclasses) for creating monitoring
requests. These classes identify the unique path to each hardware resource supported by the monitor.
Two similar resource paths exist for each hardware resource - an event path used for creating event
monitoring requests, and a status path used for creating PSM monitoring requests.
