Within the monitored environment represented by the RTSM, a CI can impact business entities and SLAs, either via a direct Impact link to them, or if one of the CI's ancestors is a business entity or SLA. If a CI impacts another CI, all its descendants also impact the CI.
How to Modify which CI Types are Monitored
By default, the Business Impact component shows the following CI types (CITs), if they are have an Impact relationship with the selected CI: BusinessService, BusinessProcess, and BusinessApplications. To modify which CITs are monitored, perform the following:
-
Select Administration > RTSM Administration > Modeling Studio. In the Modeling > Resources tab, select Queries, and open the SearchForBusinessImpact query.
Within this query, the ITU_Triggered node represents the CI selected in a view, and the Business Element node represents the CITs which can be impacted by this CI.
-
Right-click the Business Element node and select Query Node Properties to open the Query Node Properties dialog box.
-
Within the Element tab, modify the query to add or remove CITs. When modifying the query, use an Or relationship between CIs, rather than an And relationship. For details, see the RTSM Modeling section.
Do not change the name of the SearchForBusinessImpact query, or the name of the ITU_Triggered node.
How to Modify Which CI Relationships are Monitored
By default, the Business Impact component shows Business Services, Business Processes, and Application CI types (CITs), if they have an Impact relationship with the selected CI. To modify which relationships are displayed, perform the following :
-
Select Administration > RTSM Administration > Modeling Studio. In the Resources tab, select Queries, and open the SearchForBusinessImpact query.
-
Right-click the Virtual Compound relationship (right-click the arrow itself) and select Edit Compound Relationship. Within the Add Compound Relationship dialog box, modify the relationships monitored by the query. For details, see the RTSM Modeling section.
How the Business Impact Rating is Calculated
The business impact rating can be calculated based on the following metrics:
-
The criticality of the impacted business CIs, as defined by the Criticality attribute on these CIs.
-
The number of business services impacted by the CI.
-
The number of SLAs impacted by the CI.
If you choose to use the criticality factor only, the impact is calculated as follows: Within the RTSM, each business CI can have a BusinessCriticality attribute defined, with a value of 1-5. If a CI has an impact on one or more CIs that have this attribute defined, the CI's business impact rating is the highest criticality of the CIs that it impacts.
For example, if CI-a has Impact links to CI-b and CI-c, and these two CIs have a criticality of 1 and 3 respectively, the business impact rating for CI-a displayed in the Business Impact component is 3, based on the highest criticality of the CIs that it impacts.
Customizing the Business Impact Rating
You can customize how the business impact rating is calculated by:
-
Including or excluding any of the above metrics (criticality, number of business CIs, or SLAs) in the calculation.
-
Calculating criticality based on average criticality, or highest criticality (default).
-
Assigning each metric a specific weight; for example, you can make one of the metrics more significant in the calculation than the others.
-
Assigning thresholds to the metrics that count business entities and SLAs, so that instead of calculating based on simple average, different values are used.
These customizations are defined within an XML file in the infrastructure settings, as described in How to Customize the Business Impact Calculation Method.
