CMDB Heath Dashboard Jobs: How to run the Health jobs on filtered CIs

[RahulY00040]

Hello friends,

We don't have CMDB Health Jobs configured and running. I would like to configure one for targeted set of CIs that I can filter, so that i can measure CI - 3Cs at least for filtered CIs. Anyone has any idea, please help.

Thanks in advance,
Rahul

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.

To target specific CIs for the 3Cs (Completeness, Compliance, and Correctness), you should use CMDB Health Inclusion Rules. Navigate to CMDB Health Preferences and create a rule for your desired CI class, adding filters to narrow down the specific records you want to measure. Once your filters are set, you can configure the health metrics in the CI Class Manager and execute the CMDB Health Dashboard scheduled jobs to generate scores only for those filtered CIs.
