An Overview of ITO Processes
Understanding ITO Processes
distribution session. In addition, scripts and programs
required for automatic and operator-initiated actions,
scheduled actions, monitoring and broadcasting
requests, can also be distributed via the distribution
manager. The distribution manager also starts a child
process, the communication manager, for inter-
management-sever communication.
opcecm The event-correlation manager connects to the
Server MSI to allow access to and modification of
messages from the ITO message flow by the event-
correlation (EC) engine. Depending on filters and
conditions, the messages are then correlated and
written back to ITO and appear in the
Message
Details window (available from the Message
Browser) with the message source: MSI opcecm. Like
all server processes,
opcecm is controlled by the control
manager, opcctlm .
opcmsgm The message manager receives messages from the
managed nodes via the message receiver (
opcmsgr ).
The messages can be re-grouped and logged by the
message manager running on the management server.
The message manager is also responsible for adding
annotations, triggering notifications, and for
forwarding the message to the trouble-ticket and
notification-service manager for external
notification and trouble- ticket generation.
opcforwm The message forwarding manager relieves the
message manager
opcmsgm of time-consuming tasks,
such as sending messages to remote managers, in order
to allow the message manager to manage messages
more effectively. On the local, “source” management
server, the message-forwarding manager receives data
from the message manager (in the form of messages),
the action manager (action responses) and the display
manager (message operations such as acknowledge,
add annotation, and so on).
The message-forwarding manager sends data to the
message receiver on the “target” management
server(s).
