The primary components of OVO are:
• OVO Agent—The OVO agent processes run on managed nodes
throughout the environment to collect messages from the processes
running on those nodes. The OVO agent filters and formats these
messages according to information in configured message source
templates. It then forwards relevant information in the form of OVO
messages to the OVO server. The OVO server responds with actions to
prevent or correct problems on the managed nodes and passes the
messages to the message browser in the OVO operator GUI.
The OVO agent on the OVO server machine receives new problem
and status messages from the OV Topology Server. The OVO agent
formats these messages and forwards them to the OVO server. This
OVO agent also performs self-management by reading OVO server
software and machine operating system log files and creating and
sending applicable messages to the OVO server.
• OVO server—The OVO server receives formatted messages from all
managed nodes. It manages these messages, initiating automatic
actions as necessary, and groups messages according to the current
configuration. The OVO server updates the messages and status
information displayed in the OVO GUI. Additionally, the OVO server
can forward messages to other management servers and can install,
configure, and update the OVO agent software on managed nodes.
• OVO GUI—The OVO GUI displays the managed nodes in the node
bank. This node bank includes the topology of the managed telecom
network elements. The OVO GUI also includes message groups,
applications, and services. The OVO GUI message browser displays
formatted messages received from all managed devices and
applications. Problems displayed in the message browser also appear
in the optional topology GUI’s problems presenters.
The network operators interact with the information presented in the
OVO GUI to know the condition of the managed nodes they are
responsible to maintain and to set priorities for their work day.
• Service Navigator—Service Navigator is an optional add-on
product to the OVO Telecom Agent that provides visual data about
the availability of the services in the network. Service Navigator
displays a hierarchy of services and shows the current status of each
service. It defines relationships between these services and managed
