Glossary
A
Application An application is a set of processes.
APPLIDEF Domain APPLIDEF represents application software that is executing on the system. The
application software is made of a maximum of 80 named processes.
APPLIFILE Domain APPLIFILE represents the I/O executed by an application against a local or a
remote file. The application consists of named processes. The file may be a local file
(by default) or a remote file.
B
Basic Collector The Basic Collector is the collector process that collects entities on different CPUs.
BASE24DEF Domain BASE24DEF represents the features of a user application.
C
cfg A .cfg file contains Host configuration information. A user can save Host configuration
information to a .cfg file by exporting and saving the information. This file can later be imported.
Correlation Correlation is a technique, which can show whether and how strongly pairs of
variables are related. This is used by the OVNPM Display Agent to compare,
correlate, & display matrix data.
Collect Manager The Collect Manager manages the Basic Collector and builds aggregate counters
Collect Interval Period of time where OVNPM collects data, that is, complete Measurement.
Configuration OVNPM Configuration defines how the instances (i.e. entities, objects) will be monitored. It also
defines the instances to be monitors. Installation phase determines the obvious instances to
monitor
OVNPM Configuration subvolume contains the OVNPM configuration file
CPU Domain CPU represents the individual CPUs that make up an HP NonStop system.
D
Display Agent. The Display Agent is the Windows-based GUI of OVNPM. The Display Agent requests
information from the OVNPM components on the Nonstop Server to satisfy end-user requests and
then displays this information in an organized and meaningful way.
Data Retention Data retention period is the number of days to retain data in the database. The longer
the period to retain data, the more days of recent performance history is available for
review. However, you must consider the amount of file space needed to store this
information
DISK The DISK domain represents the individual disks that are installed on an HP NonStop
system.
Domain A Domain is an entity type that makes up your system such as a Disk or CPU. A
domain may contain other domains called sub-domains, which have their own sub-
domains. Metric and instances belong to a domain. For example, $SYSTEM is an
instance of domain DISC. Metric disc-space-busy.% is a metric of domain DISK.
DISKFILE Domain DISKFILE represents the activity on a disk file.
DSV DSV stands for Distributed Server for OVNPM. Distributed OVNPM (DSV) gives a user
access to OVNPM subsystems installed on multiple remote HP NonStop nodes from a
single Display Agent. The nodes must be part of an HP NonStop EXPAND network
