Working with Message Templates
You can use message templates to filter and suppress messages, reformat
message text, and link actions and instructions with a message. You can
define message templates using the Message Source Templates
window that is accessible to both the VPO administrator and the VPO
template administrator.
By configuring VPO templates, you can specify which message source is
to be used, and how it is employed. You can choose which events detected
through the message source are relevant to justify a message to be
generated and sent to the management server, or which are irrelevant
and can be suppressed. If a message is generated for an event, the
template specifies the composition of the message, its attributes, and the
instructions, annotations, and actions to be associated with the message.
For more information about configuring message templates, see the VPO
Concepts Guide and the VPO Administrator’s Guide to Online
Information.
❏ Basic Template Properties
These include the template name and description, a specification of
the message source to be used and how to use it. For example, the
name of a logfile to read, the program used to preprocess the logfile,
the time interval for checking the logfile, etc.
In addition, the basic template properties include the defaults that
are used to set the attributes for generated messages if no additional
information is specified, for example, default severity, default
message group, etc.
❏ Template Conditions
A list of conditions belongs to each message template. You can
choose either suppress matched conditions or suppress
unmatched conditions to filter out irrelevant events, or choose
message conditions to extract relevant events and forward them to
the Message Browser. Both message and suppress conditions can be
placed in any order, and they are processed by VPO in the order in
which they are listed. The first matching condition determines how
VPO reacts to an event, so the sequence of conditions in the condition
list must be carefully considered.
