    • Click the Services tab and click an individual service heat map or tile.
    • You can view the following details of each service:

      • Service name, severity, incident ID associated with the service, service impact score in percentage, and the date and time when the service was last updated.
      • Top 3 impacted entities (business services) that are associated with the service. In this example, Core_Banking_CIs is an impacted service with the impacted entities LDAP Service and Log Servers.
      • Health score for the selected time range. You can hover over a time slot to view the health score. For more information, see Service health score, impact score, and metrics.
      • Legends to indicate incidents, events, and change requests on the health timeline. Hover over an event, incident, or change request to view the details. For more information, see Total incident count and mean time to resolve (MTTR) indicators for a reliable incidence-response process. The health timeline does not display the INFO and OK events.
      • Pie chart displaying the count of open events impacting the service. The events are categorized by event status. The pie chart does not consider the INFO and OK events while displaying the event count. You can click the pie chart to view the list of all impacting events and additional event details.
      • Incident ID, if an incident is created for an impacted service. Click the link to launch the incident details page in BMC Helix IT Service Management  – SmartIT (Must have permissions to view incidents in BMC Helix IT Service Management ).

    To run automations, see  Remediating events for services and situations Open link .
  5. Click Action and perform any of the available actions for the open events.
    To perform actions, see To perform event actions for an impacted service.


To perform event actions for an impacted service

The capabilities available for your organization and your user role determine the event actions that you can perform against the open events. The following table describes the basic event actions.

Action

Description

Create Automation

Launches the BMC Helix Intelligent Automation > Create Automation Policy page to enable tenant administrators to create an automation policy.

Requires Intelligent Automations feature to be enabled from the Configurations > Manage Product Features page.

For more information, see  Creating automation policies Open link

Request Automation

Displays the Request Automation dialog box.

Requires Intelligent Automations feature to be enabled from the Configurations > Manage Product Features page.

For instructions on how to raise a request, see  Requesting for a new automation Open link .

Acknowledge Event

Recognizes the existence of an open event. This operation changes the event status from Open to Acknowledged.

Assign Event

Assigns ownership of an open, acknowledged, or assigned event to yourself or another person in the same account. This operation changes the event status from Open or Acknowledged to Assigned, and the event owner is updated with the selected user. If the event status is Assigned, only the ownership changes to the selected user.

Close Event

Disables any further event operations on the event. Closed events are not considered for calculating the status of a device.

You can close events with statuses Open, Assigned, and Acknowledged only.

Decline OwnershipRemoves ownership of an event in the assigned state. This operation changes the event status to Acknowledged.
Set Event PriorityAssigns a priority level to the event.
Take OwnershipAssigns ownership of Open or Acknowledged event to yourself.
Unknowledge EventChanges a previously Acknowledged event back to the Open state.

For more information about the impact of the actions on the event, see Performing event operations in the BMC Helix Operations Management  online documentation. 

To view the topological map of the service CIs

  1. Click CI Topology to view the topological map of the service CIs and view the node details.

    CI node display color

    The CI topology nodes are displayed as per the node impact severity status and the CI impact path between the impacted nodes is marked with dotted red lines, and the non-impacted nodes is marked with grey lines as shown in this image.

    • (Optional) Use the various display options to maximize/minimize, drag or position, zoom in/out, and fit to center the topology map.
    • From the map, select any node to view the node details.
    • (Optional) Change the topology hierarchy, enable or disable aggregation by CI Kind.
    • (Optional) Modify the advanced filter to control the view of topology map.
      Based on the length of the selected criteria and available space to display, the filters are automatically tagged and grouped as +1 active, +2 active, and so on. You can click the tagged number to view the additional filters.


To view service hierarchy

  1. Click Service Hierarchy to view the service node details of parent and child services.
  2. Click Upstream Impact, Downstream Impact, or both to view the upstream (parent nodes) or downstream (child nodes) impact paths of the current service.


To view metrics for an impacted service

Click Metrics to view the metrics chart for the top attributes of the causal node. If there are more than three metrics, only the top three trending metrics are displayed.
Based on the metric data and its trend, you can take action to resolve the issue. For more information, see Service health score, impact score, and metrics.
