Event correlation manager that connects to the
server MSI to allow access to and modification of
messages from the HPOM message flow by the event
correlation (EC) engine. Depending on filters and
conditions, the messages are then correlated and
written back to HPOM. The messages display in the
Message Details window (available from the Message
Browser) with the message source MSI opcecm. Like
all server processes, the event correlation manager is
controlled by the control manager, opcctlm.
Annotation server that runs on the management
server and obtains data from outside the ECS engine
for use within correlation circuits. This process
connects to the opcecm process using the standard
annotate API. It receives annotate requests for
launching external programs and returns the output to
the circuit.
Message manager that receives messages from the
managed nodes through the message receiver
(opcmsgrb). The messages can be correlated, regrouped
and logged by the message manager running on the
management server. The message manager is also
responsible for adding annotations, triggering
notifications, and forwarding the message to the
trouble ticket and notification service manager
for external notification and trouble ticket generation.
Message forwarding manager that relieves the
message manager, opcmsgm, of time-consuming tasks
(for example, sending messages to remote managers).
This relief allows 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 servers.
