Create event rules to explicitly allow binding of metric events to host
CIs.

## Before you begin

Role required: evt_mgmt_admin

## About this task

Starting with the London
release, Metric 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 Metric 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 AllEvent ManagementRulesEvent Rules to open the event rule designer.
2. Click New and ensure that the Active toggle switch ![Active toggle switch]() is set to the right (Active).
3. On the Event Rule Info tab:
   1. Set Source to the data source that this rule applies to.
   2. **Optional:** Enter a Description such as <kbd class="ph userinput">Bind metrics at host level</kbd>.
   {#event-rule-bind-metrics-to-host__substeps_s5q_pqs_kfb}
4. On the Event Filter tab, set a filter condition to indicate that Classification is Metric.
5. Click Save.
