Bradley:

pre-Jakarta, there is no easy way to filter out CIs from the dashboard from being measured.   In Jakarta, we introduced something called the Health Inclusion Rules, which is a query we run against the CI Classes before we run the CMDB Health Dashboard measurements.

Pre Jakarta, there are some things you can do.   For stale CIs, you can setup a job that updates the field Most Recent Discovery (last_updated) field to the current date/time and they will not come up stale.

Orphans already use a filter so this may not be an issue.

Hi Richard,

In the Jakarta Health Inclusion Rules will it only be possible to filter out classes or will there be other options e.g. to filter out CIs with a specified status?

The dashboard is unlikely to work for us without a filter because we don't delete CIs but keep them under a different status and don't want them measured

thanks, Kate

Hi Richard,

May be I am trying something very stupid. But can I run my orphan rule using conditions like I have mentioned in screenshot?

I want to check only limited classes for orphans.

[richardbrounste]

I don't see your screenshot. But you can't apply a filter condition to an Orphan rule until Jakarta. In Jakarta we are introducing Health Inclusion Rules in the CI Class Manager, which is a filter of conditions applied to the CIs before it runs the Orphan Rule.

I am trying to run orphan rule for only active and not for retired CIs ones.

Will this work?

Or I should ask, what will it retrieve me?

I am setting condition for orphan rule as Active is 'True'

and CI Status is 'not Retired'. I have also checked 'No relationship' to True.

Will it only run this rule for all Active and non retired CIs?

Or will it mark all Active and non retired as Orphan?

Thanks,

Swapnil.
