How to Adjust Propagation and Calculation

In a view, KPIs are calculated based on the view topology in the RTSM. When you modify KPI or health indicator (HI) definitions on a CI, your changes are reflected in all views which contain the CI, across OMi.

You can modify which KPIs are displayed in a view, and which are included in the calculation of a CI.

For details on defining which KPIs to include in CI calculations, see KPIs in Views.

Business Rules are KPI calculation rules that receive the data collected from CIs, process the data, and generate KPI statuses based on these calculations. The rules calculate key performance indicators (KPIs) based on the status or value of HIs and other KPIs.

For details about editing and adding business rules, see Business Rules.

When a KPI is assigned to a CI or a CI is attached to another CI, the propagation mechanism propagates the appropriate KPIs to the parent CIs. By default, when a KPI is assigned to a CI, the KPI is automatically propagated to the CI's parents. KPIs are propagated from child CIs to parent CIs; HIs are not propagated to parent CIs.

For details about editing and adding propagation rules, see Propagation Rules.

Each business rule uses various rule parameters that can be customized, either globally in the rule repository, or on a specific instance of a KPI or HI by using the CI Customizations page.

For example, you can modify the Trend and History Calculation rule to change the way the trend and history statuses are calculated and displayed, by editing the hidden rule parameters.
