Hi @RahulY00040 ,
you can measure the 3Cs (Completeness, Correctness, Compliance) for a targeted set of CIs by using CMDB Groups, which effectively act as a filter for CMDB Health dashboards.
Below is a step-by-step approach to achieve this.
1️⃣ Create a CMDB Group (This acts as your CI “filter”)
Think of a CMDB Group as a logical container for the CIs you want to measure (for example: only Linux servers, only production CIs, only Discovery-sourced CIs).
Navigation: Configuration > CMDB Groups
Backend Table:cmdb_group
What to do:
Click New
Give the group a meaningful name (example: Critical Linux Servers)
Make sure the Group Type includes “Health”
Save the record
Now, in the CMDB Group Queries related list:
Add one or more queries to define your scope
(for example: Class = Linux Server, Environment = Prod, Discovery source, etc.)
👉 This is where you “filter” your CIs. Any CI matching these queries becomes part of the group automatically.
2️⃣ Configure Group Thresholds (This links the Group to the 3Cs)
This is the bridge between your CMDB Group and CMDB Health metrics.
Navigation (via filter navigator): cmdb_health_scorecard_group_threshold.list
What to do:
Click New
Select your CMDB Group from Step 1
Choose a Metric (for example: Completeness)
Define thresholds:
Lower Threshold (example: 10%)
Upper Threshold (example: 30%)
Repeat this step for below metrics:
Correctness
Compliance
This tells ServiceNow how to score and classify health for only the CIs in this group.
3️⃣ Execute CMDB Health Calculation Jobs
CMDB Health scores won’t appear unless the background jobs are active and executed.
Navigation: System Definition > Scheduled Jobs
Backend Table:sys_trigger
What to look for:
Search for jobs with names starting with “CMDB Health Dashboard”, such as:
CMDB Health Dashboard – Completeness Score Calculation
CMDB Health Dashboard – Compliance Score Calculation
CMDB Health Dashboard – Correctness Score Calculation
For each job:
Open it
Set Active = true
Click Execute Now (for initial results)
4️⃣ View Health Results for Your Targeted CI Group
Navigation: CMDB Workspace> Home > under quick link section CMDB health Dashboard >
At the top of the dashboard:
Change the Class selector to Group
Select your CMDB Group
- The dashboard will now show Completeness, Correctness, and Compliance scores only for the CIs in that group.
If this helpful mark it as helpful and accept my solution
