ALM Assets Table VS Computer CMDB Table

GChat · ‎06-23-2025

Hi There,

We've been making changes with our computers and I'm running into a small issue between the CMDB Manager and the Computer Class owner over which table I should be basing my numbers off. ALM_ASSETS vs CMDB_CI_COMPUTER.

Can anyone help me with how to choose between the 2 and what is the best option?

I know Alm Assets contains more of the financial and Lifecycle info but what are the main differences between the 2 and which do you generally run your numbers off?

Hi @GChat ,

Choosing Which Table to Report On

1: Define the Purpose of the Report

If your report is operational (e.g., how many active devices are discovered, incidents per laptop, OS distribution) use cmdb_ci_computer.
If your report is financial or lifecycle-related (e.g., asset aging, assignment, lease expiry, device refresh planning) use alm_asset.

2: Understand the Link Between the Two

Each record in alm_asset (if created properly) should reference a corresponding CI in cmdb_ci_computer using the CI reference field.
But not all CIs have a linked asset (e.g., discovered test VMs), and not all assets have CIs (e.g., new in-stock devices).

3: Validate Your Data

Cross-check: Run reports to identify how many assets have linked CIs and vice versa.
Understand the data health: Missing links can skew your reporting.

4: Align with Use Case Owners

CMDB Manager will advocate for data in cmdb_ci_computer due to accuracy via discovery.
Asset Manager/Owner will prefer alm_asset for lifecycle and ownership accuracy.

The ideal solution is to create a joined report:

Start from alm_asset and pull in fields from the linked CI (alm_asset.ci) - that way you get both lifecycle and technical data.

Recommendations

1 - Use alm_asset as your base when the report involves:

Lifecycle stage (In Use, In Stock, Retired)
Financials (cost, depreciation, PO)
Ownership (assigned to, location)
Compliance (e.g., warranty expired)

2: Use cmdb_ci_computer when you need:

Accurate hardware/software specs
IPs, hostnames, discovered data
Real-time status from Discovery

Common Pitfalls

Assets not linked to CIs → leads to missing data in joined reports.
Duplicate CIs from multiple discovery sources (SCCM, JAMF, etc.).
Over-reliance on either table without data governance.

Action Plan

Run a data audit:
- % of assets linked to CIs.
- % of discovered CIs without assets.

Define business KPIs:
- Choose table based on what’s being measured.
Propose a unified report:
Use alm_asset as the base → join cmdb_ci_computer via ci field.
