Using the Integration Capabilities of the VPO Motif-based GUI
Event Integration Through Messages
Chapter 3 135
❏ It is recommended to enable the output of messages to the agent and
server message stream interface (MSI) in the Message Condition
Advanced Options window for the following reasons:
• The server MSI can always be globally disabled using the
Configure Management Server window. By default, the server
MSI is disabled.
• If the server MSI is not enabled, and at a later stage the customer
decides to connect an external application to the MSI, they would
need to modify all relevant conditions in all templates manually.
• To prevent an application connected to the server MSI from being
swamped with messages, the API can register conditions with the
management server, which effectively filters the message stream
flowing to the interface.
Consider the following points when choosing whether to divert or
copy messages to the server MSI:
• If you choose to divert a message, there is a possibility that the
application could remove the message from the message stream so
that it is never displayed in a Message Browser. If you consider a
message to be important, choose to copy it to the MSI.
• When the copying of messages to the MSI is enabled, not even an
event correlation engine can remove a message from the message
stream. This result may not be desired if you use an event
correlation engine to reduce the number of messages reaching the
management server.
❏ Configure templates for your integration so that the VPO operators
are always informed about any problems caused by the partner
solution. For example, make sure that any known messages of the
partner solution trigger VPO messages.
