An Introduction to Integrating Partner Applications with VPO
VPO Conceptual Overview
Chapter 1 35
To achieve efficient operation and problem management, information
must be gathered from the controlled elements and resources. VPO
Agents are installed on managed nodes throughout the management
domain which gather status information, messages, and monitoring
values from a range of sources. SNMP agents, hosted on any system or IP
device, are also fully supported by VPO. Message filters and thresholds
are used to ensure that only the relevant information is sent to the
management server and presented to the responsible VPO operators.
After collecting data, VPO combines all events received from the
managed environment into a single procedural flow, or message
stream. In addition to conditional event filtering and the suppression of
unwanted messages, the HP OpenView Event Correlation Services
(ECS) can tap the message stream on both the management server and
the intelligent agents to reduce the volume of messages reaching the
VPO Message Browser. This guarantees the maximum possible
efficiency in local and central event analysis and handling. VPO provides
multiple mechanisms, such as automatic actions, predefined
operator-initiated actions, or problem-specific help text and instructions,
to help the operator resolve critical conditions. The agent can even
initiate and execute corrective actions without any involvement from the
management server.
Besides configuration data, all status information gathered, including
records that document completed actions, are stored in a central SQL
database. The database offers an excellent starting point for future
audits and analyses, and provides a central configuration of remote VPO
domains.
You can easily adapt VPO to fit into existing IT infrastructures and
adjust the managed environment at any time. The fully-customizable
environment ensures a match of different skills, tasks, and
responsibilities, and provides opportunities for task delegation. This
enables multiple VPO operators to work together simultaneously in the
same computing environment, without a duplication of effort.
In the area of network management, VPO provides powerful features for
the discovery and mapping of networks which enable VPO operators to
view the complete managed environment in the following ways:
❏ a logical (system) view
❏ a topological (network) view
❏ a service view (with the HP OpenView VantagePoint Navigator)
