Subscribing to the event

Event and notification subscriptions in the Global Manager are configured within dxa configuration files by using the sub keyword. Patterns (regular expressions) separated by "::" match the class name, instance name, and event name in the Domain Manager.

The syntax is as follows:

sub <classPattern>::<instancePattern>::<eventPattern>/<modifiers>

where:

• <classPattern> is the pattern to match for the class name.

• <instancePattern> is the pattern to match for the name of the instance.

• <eventPattern> is the pattern to match for the name of the problem or event.

• <modifiers> can have the following values:

  • p = problem

  • e = event

  • a = aggregates

  • n = notifications

    For example:

    # Subscriptions
    .
    .
    sub     ICIM_UnitaryComputerSystem::.*::DiscoveryError/e
    sub     ICIM_UnitaryComputerSystem::.*::Unresponsive/e
    .
    .
    

    To subscribe to a new event, add a line to this Subscriptions section. For example, to subscribe to a new IPForwardingOn event in the Host class, the following line is added:

    sub  Host::.*::IPForwardingOn/e
