Drift management to track changes in the CMDB
Important
Drift Management has been deprecated from BMC CMDB. The documentation provided for Drift Management is also deprecated and provided for information only.
See Deprecated features.
This use case describes the ways in which you can track changes in your CMDB. To perform auditing, verification, and management of infrastructure changes in your IT environment, you must first know the difference between the current physical state of your IT environment and the expected or correct state of your environment. Drift management helps you keep your data center operationally compliant with the business rules of your IT environment.
Drift management scenario
Drift management workflow
The following workflow describes the general steps of drift management:
- A snapshot of the initial state of the dataset is captured by the snapshot job and is used as a baseline for comparison later.
- Later, Discovery updates the dataset with CIs that may have changed and this is used as the target for comparison with the baseline.
- The comparison job compares the baseline snapshot to the target dataset.
- The output of the comparison job can be either used for change management or incident management depending on the use case.
The data on the compared CIs can also be used by a comparison service. - The list of detected CIs can be either displayed or exported to the drift report.
