An Introduction to Integrating Partner Applications with VPO
Integration Facilities Provided by VPO
Chapter 160
VPO provides the following mechanisms to support problem resolution
and self-attended operation:
❏ Message Instructions
These help an operator to solve the problem at hand. They describe
the available automatic and operator-initiated actions, give advice
about manual steps for solving the problem, and provide any
additional explanation that might be useful to an operator.
You can define a default instruction text at the template level, and
then define more specific instructions for each message condition of a
template.
❏ Message Annotations
You can associate any text with a message as an annotation. In
contrast to message instructions, annotations are intended to be
extended as a message is processed. For example, you might provide
the output of automatic and operator-initiated actions to the
operators as an annotation.
An operator can later add comments about how the problem was
solved to share this information with colleagues who might search the
message history log if they encounter a similar problem.
❏ Automatic Actions
VPO can invoke actions automatically as a reaction to specific events.
An action can be any shell command line, with parameters if
necessary, that does not require human interaction.
Automatic actions can either be performed on the node on which the
message was generated (local automatic actions) or on any other
node. Local automatic actions do not require communication with the
VPO management server and thus are performed even if the network
is down or the VPO management server is not available.
You can even specify that successful completion of the automatic
action automatically acknowledges the related message, i.e. the
message is no longer displayed in the operator’s message browser.
