Turn Off discovery for some selected Classes

[uzzawal]

Hello Experts,

I have requirement to turn off the discovery for some of the unwanted classes. Example: DNS Names(cmdb_ci_dns_name).

Please let me know the best approach to disable complete discovery for particular class so that it doesn't pull any data into this table.

Thanks in Advance !

There are two types of situations to disable discovery from creating certain classes.

The first is the hardware classes such as Linux or Network gear, which is easily done by disabling the classifier or creating a behavior to avoid discovery certain ports.

The second seems to be your situation that is to avoid creating the CI relationships such as dns, disks, or network adapters. This is a bit more of a challenge as these details are found in probes and sensors kicked off by discovery process. When you want to stop this you would have to either customize the probe or remove it from the classifier as a probe that is kicked off. This is usually harder to maintain and require a bit more digging to figure out which probe is generating them.

You could also create an ACL on that table that does not allow the create operation for any users with the mid_server role. This would prevent any creations from taking place. Or build a business rule to flag the creation of any records in a specific table that are created with the mid server user. You can then report on these or run a scheduled job on periodic basis to delete the records if not needed.

I liked the first option by ACLs, is there anything we can stop at discovery level itself.
