1 ACCEPTED SOLUTION

JA:

There are a couple of approaches to this:

1. From the Asset table (Hardware, etc) look for all records with an empty cmdb ci field.  Those will not necessarily have an analog in the CMDB table.

2. From the CMDB tables look for all records with the Asset field not filled in.  Those will likely not have an analog in the Asset tables.

Not all assets will generate CMDB records automatically and visa-versa.  It depends on how your Model Category table is configured.  It also depends on when it was implemented.

This kind of diff reporting takes patience and time.  There is no quick process for this.

cmdb_ci_vm_instance extends from CMDB_ci_vm_object table which extends off Configuration Item table.  I cheated and looked it up.  It is not under Hardware hierarchy.

We are getting ready to depict applications for each environment to have relationships built for production environment, versus development environment, etc.
