About this task

Starting with the London release, Operational Intelligence no longer relies on the default Event Management binding workflow which binds nodes to host CIs. Event Management is configured to apply the default host binding algorithm when an event rule cannot find a CI to bind to, based on event data. In Operational Intelligence, with a given event rule and two different events, there can be a situation where one event binds to the correct CI and another event cannot bind. In this case, the same metric types would be created for the selected CI and for the host level CI, causing confusion.

For example: With an event rule that binds the disk percentage metric to a storage disk, one event can find a disk CI and another event cannot. This results in the disk percentage metric being created for a disk CI and for a host CI.

To avoid this confusion, Event Management default host binding is disabled for metric events in the base system. To allow host binding for metric events, explicitly create the following event rule in the Event Management event rule designer. The underlying binding functionality of the event rule designer is used to map metrics to CIs.

Procedure

  1. Navigate to Event Management > Rules > Event Rules to open the event rule designer.
  2. Click New and ensure that the rule is set to Active.
  3. On the Event Rule Info tab:
    1. Set Source to the data source that this rule applies to.
    2. Enter a Description such as Bind metrics at host level.
  4. On the Event Filter tab, set All of these conditions must be met to Classification is Metric.
  5. Click Save.
