Ask the Expert: Setting up the CMDB Health metrics and applying them to a real world CMDB

[Lisa Latour]

Join us on this discussion page for a YouTube Live Presentation on setting up CMDB health metrics and how to apply them.

It's an opportunity to see how the new CMDB Health Dashboard can help you manage the data quality of server and network device data. This new dashboard provides an actionable view of CI health and a remediation framework to take corrective actions.

The infrastructure is hosted with the service provider. We have set up an integration between the service providers CMDB (HP uCMDB) and our CMDB.

The class used to represent the AIX LPARs is the AIX Server class, and therefore we cannot immediately use the LPAR class instead...

Hi

How will the dashboard's and the calculation work in a domain separated instance?

Best regards

Stig

From the documentation in Istanbul:

https://docs.servicenow.com/bundle/istanbul-servicenow-platform/page/product/configuration-management/concept/c_CMDBHealth.html

CMDB Health is domain aware. If the domain separation plugin has been activated, then the CMDB dashboard displays health based on data, rules, and settings from the logged-on user domain. If rules and settings are not defined for a child domain, then the parent's settings are applied, recursively.

Giving access to my itl_admin and ecmdb_admin to work with the module (istanbul), but seems to have Issue with access rights:

- If I'm and Ititl_admin or ecmdb_admin I'm not able to see dictionary entries, is there any reason why this form is shown at all?

- When click on a class, table dictionary shows up but all columns/attribues are restricted due to security, is this intended and does it have any impact on the functionality?

- not able to configure rules and properties - all field are read only?

Create or edit a CMDB Health staleness rule

If the CMDB Health sub-metric staleness is in effect, then staleness rules are used to determine the percentage of stale CIs in the CMDB. This sum is then aggregated into the correctness metric, and weighs into the overall CMDB health calculation. Staleness rules are defined per class per data source.

Before you begin

Role required: itil_admin (on top of itil)

[richardbrounste]

The itil_admin role is designed to allow non-admin users to configure the Health Dashboard settings for Staleness, Duplicates, Orphans, Compliance and recommended fields. It will not allow you to update CI Classes in the data dictionary.
