• CMDB Baseline created for "cmdb_ci_hardware" table doesn't capture the changes made to the fields of any CIs.

• Any release

The probable cause would be,

• some CIs may not have existed at the time the baseline was created, and
• it only lists changes of the CI's since the baseline was re-created.

In order to fix the issue,

• Delete the existing Baseline which is in place and create a new Baseline. (e.g. Name "Hardware baseline" for "cmdb_ci_hardware" table.)
• Once the baseline calculation gets completed, take 2 CI's from different table and perform the changes to the fields.
• In this case, a CI from the table "u_cmdb_ci_hybrid_device" and another CI from "cmdb_ci_linux_server" were taken and tried changing a few field attributes.
• The changes made to the CI from the table "u_cmdb_ci_hybrid_device" weren't captured in the baseline because the corresponding table "u_cmdb_ci_hybrid_device" was not audited.

• The changes made to the CI from the table "cmdb_ci_linux_server" were captured in the baseline because the table "cmdb_ci_linux_server" was audited.

Behavior:

• The baseline for the table will be calculated only when the corresponding table is Audited.
