View CMDB benchmarks

CMDB calculates several CMDB Health benchmarks which then display in the Benchmarks dashboard. These benchmarks are based on various CMDB Health metrics, displaying monthly averages, trends, comparisons to industry averages of your ServiceNow peers, and global benchmarks.

Before you begin

The CMDB Health Dashboard jobs must be enabled and health data must be collected. Also, navigate to Benchmarks > Setup and ensure that the CMDB KPIs are enabled under IT Operations Management.

About this task

CMDB provides the following benchmarks:
  • % of non-compliant CIs
  • % of duplicate CIs
  • % of stale CIs
For an instance, each of these benchmarks is the calculated monthly average for the corresponding CMDB Health metric. Calculating a monthly average requires that there is a metric result value for each day of the month. Therefore, each day on which the respective Health Dashboard job did not run, is assumed with the aggregated result from the run that is most recent to that day. The monthly average is then calculated based on the sum of all the daily aggregated results for the metric in that month, divided by the number of days of the month. For a CMDB Health Dashboard job that ran multiple times in a single day, only the results of the last run in that day are used for the monthly average calculation.
Note: The frequency of CMDB Health Dashboard job executions depend on whether the job is enabled, its schedule and on manual runs.

Global averages are based on the sum of monthly averages of all peer instances, divided by the number of instances (aside from instances for which the monthly average is 0).
