Managing relationships between a configuration item and other CMDB instances
A CMDB instance represents a record in the BMC Remedyforce CMDB, which can be classified as a Configuration Item (CI), asset, or CI and asset. Each instance has configurable properties or attributes. You can attach supporting information about instances in the form of documents or URLs. You can also establish a relationship among instances in your environment. For example, you can establish a relationship among a monitor, keyboard, processor, and other items that make a computer system. Your staff members can also link CI and asset instances to change requests, incidents, problems, releases, tasks, and knowledge articles.
Depending on the CI and asset management configurations, CIs and assets in the Remedyforce CMDB affect each other as follows:
- If both CI and IT asset management are enabled, CIs and assets interrelate and affect one another. CI to CI, CI to asset, asset to asset, and asset to CI relationships exist.
- If only CI management is enabled, only CIs interrelate and affect one another. CI to CI relationships exist.
- If only asset management is enabled, only assets interrelate and affect one another. Asset to asset relationships exist.
Storing these relationships in the BMC Remedyforce CMDB enables you to see how the CMDB instances interrelate and affect one another. The use of relationships is a feature that differentiates between a CMDB and an asset store.
Relationships can be simple, such as a disk drive being a component of a computer system, or more complex. Relationships exist not only between physical CIs and assets, but also between logical and conceptual CIs and assets, such as the software instances and service instance. Relationship data makes the CMDB a powerful decision support tool. Understanding the dependencies and other relationships among your CIs and assets can tell you how upgrading Processor A can improve Laptop B's performance, or which services are affected if Router C failed. Most downtime is caused by issues stemming from configuration changes. Accurate relationship information can help you prevent those issues.
