Symptoms

CMDB Dashboard not detecting duplicate CIs

Release

All

Cause

The duplicate process only query for records with the following conditions: 
(discovery_source=Unknown and updated on last 1 day) OR (discovery_source=empty)  

The reason for this query is:

  1. If a CI has a proper discovery_source, it should have been ran though Identification Engine or has been reconciled properly.
  2. The CI's with discovery_source = empty most likely hasn't been passed through Identification Engine yet.
  3. The CI with discovery_source = Unknown are the ones marked by the job itself so health results should have been generated. If the job failed the first time around the CI  discovery_source will be set up as Unknown and it it's over 1day old the duplicate jobs will not run on those CI.

Resolution

  1. Create a Reconciliation Definitions of each individual classes you wish to the rule to run on.  If you set it for the cmdb_ci_cluster (parent) it will not affect (child) cmdb_ci_win_cluster. 
  2. Set the discovery_source of all the CI to blank and rerun the health job again.
