In Istanbul and older releases, the rules for Orphans, Staleness, Recommended and Required CIs are run against all CIs in the cmdb_ci table, which is the entire CMDB. In Jakarta, the CMDB Exclusion Rules will allow you to apply a filter so that the rules will only apply to a select set of CIs. The filter can look at the Operational Status field to see if the CI is "non operational". Or it could filter out on any other field.

Swapnil:

Instead of specifying each class in your filter, you should use the "is a" on the super class.   This will apply the filter condition to all subclasses of the class.   For example, if you say:   class is a server, it will be applied to all Windows Servers and each class of Unix Servers.

Did you achieve this? I have a similar requirement

CMDB Health Dashboard seems to be very raw mechanism - are there any known issues/challenges that being faced that you are aware of?

[Kate Dowling]

A useful presentation, thank you

You suggested clearing the cache to view the most recent data - is this required by the user after every job run regardless, or will the data automatically refresh after an elapsed time?   If after an elapsed time, how long is that period please?
