Template apply options control how template metric and policy settings are applied to a target. Two template apply options are available:

• Template will completely replace all metric settings in the target: When the template is applied, all metrics and policies defined in the template will be applied to the target. Pre-existing target monitoring settings not defined in the template will be disabled: Metric thresholds will be set to NULL or blank. Policies will be disabled. This effectively eliminates alerts from these metrics and policies by clearing current severities and violations.

• Template will only override metrics that are common to both template and target: When the template is applied, only metrics and policies common to both the template and target are updated. Existing target metric and policies that do not exist in the template will remain unaffected. When this option is selected, additional template apply options are made available for metrics with key value settings.
