Adding health indicators

Health score computation for a service depends on whether you have defined only health indicators or both the health indicators and event rules: 

• Only the health indicators are defined: When thresholds are breached for these metrics, events are generated. The service health score is computed based on the impact score assigned to the severity of the health indicator event as defined in the health score configuration.
• Both the health indicators and event rules are defined: When thresholds are breached for these metrics, events are generated. However, the events generated that match the criteria defined in the event rules are considered for computing the health score. The service health score is computed based on the impact score assigned to the severity of the health indicator event as defined in the health score configuration.

To add health indicators to a service

You can add health indicators either while creating a service or while editing it.

1. Click Services and then click Create New Service. 
2. Provide the service definition.
   For more information, see Defining-a-service. 
3. Click Health Indicators.
4. Click the service (for example, Network) for which you want to add Network Utilization (%) as the health indicator.
5. In the Define Health Indicators pane, click Add Health Indicator.
6. Perform one of the following actions:
   • If you have added dynamic or static content for CIs that has metrics to select and you want to view only those metrics, select Metrics Applicable for this Service Content.
   • To view the list of all metrics, select All Available Metrics.

1. Select a CI Category (for example, Hosts & Hosts Containers) and CI Kind (for example, Host).
2. From the list of CI names displayed, expand a CI name, metric type, metric name, and then select the monitored host name and the associated entity.
   For example, for the Network service, expand Network Interface and then expand Network Utilization (%) and then select the required CI as Monitored Hostname and Entity. 
3. Click Add Metric.
   The metric you added is displayed in the Added Metrics section.

4. (Optional) In the Added Metrics section, click Create Alarm Policy or Edit Alarm Policy to add or update the alarm policy for the listed metric in BMC Helix Operations Management. 
   For example, create a policy to generate an alarm event as soon as the network utilization is above 80%.
   

   The Create Alarm Policy and Update Alarm Policy pages include the metric name as the instance name and the monitored CI Kind as the device host name in the Alarm Generation Condition section by default.For more information about creating or editing an alarm policy in BMC Helix Operations Management, see Configuring alarm policies.

5. Click Save and Close.
   The metrics you have added appear in the Define Health Indicators pane as part of first health indicator group. You can add a maximum of two such health indicator groups. During service health computation, all the health indicators that are added in these groups are considered.
6. Click Save and Close.
   The count of health indicator groups is shown as part of the Network service.
