Inform OpC

The Inform OpC alarm action enables you to send a message to Hewlett Packard's OpenView IT/Operations (IT/O). IT/O treats this message just as if it had come from an IT/O agent running on a node managed by IT/O.

Although you can use this action to send a message to IT/O at any time, the action is designed to be used in the following scenario:

1. IT/O messages are diverted to NerveCenter.
2. NerveCenter correlates the conditions described in the IT/O messages.
3. NerveCenter sends messages to IT/O describing the results of its correlation activities.

 
  To add an Inform OpC action to an alarm transition:

1. From the Transition Definition window, select the New Action button.

   A pop-up menu listing all alarm actions is displayed.

2. Select Inform OpC from the pop-up menu.

   The Inform OpC Action dialog is displayed.

3. Specify the contents of the message by entering values in the Node, Application, Group, Type, Object, Severity, and Message text fields.

   In the Node field, you can use the variable $NodeName, which contains the name of the node associated with the trigger that caused the alarm transition. Or you can type in the name of a node. Put the name inside quotation marks if it contains spaces.

   Similarly, in the remaining fields, you can leave the variables that are shown as defaults, or type in a string (using quotation marks if the string contains spaces). For descriptions of the contents of these variables, see the section Variables for Use in OpC Trigger Functions.

   If the current alarm transition was caused by a trigger fired by an OpC mask, these variables contain values taken from the IT/O message that caused the trigger to be fired. Otherwise, they contain the values used the last time that the current alarm instance performed an Inform OpC action. If the alarm instance has not performed an Inform OpC action previously, the variables contains null strings.

   Note    NerveCenter appends a string to your message text. The content of the string is determined by the type of message that prompted the current alarm transition: an OpC message, a trap, or a response to a poll. If an OpC message caused the transition, NerveCenter appends the contents of the message's fields. If a trap caused the transition, NerveCenter appends the contents of the trap and its variable bindings. If a response to a poll caused the transition, NerveCenter appends attribute/value pairs for the attributes used in the poll condition.
