Discovery picks up a pattern randomly if there are multiple active patterns on the same CI typeIssue If we see an issue with the Application service displaying different results after each discovery process, it may be a condition where different patterns are being picked up during different attempts of discovery as a result, there may be a difference in map creation. This condition may result in any of the below: On the map, the number of connections generated differs significantly for each discovery attempt.There can be new CIs appearing and disappearing on the map.The number of levels the map drills down may vary.ReleaseAnyCauseThis condition can be seen in a scenario where there are two or more specific patterns, one OOTO targeting a specific CI type and the others created manually for a requirement targeting the same CI type and if more than one is active. For example, there is an OOTB pattern, 'WebLogic', which targets the CI type cmdb_ci_app_server_weblogic and of a new pattern is created on the same class say with the name 'NT Weblogic Version 10.3', this scenario is seen when both the patterns are left active. The below screenshot will give us a context of the issue (You may see one of the patterns as active false but this issue would be seen if both the patterns are active) ResolutionAs a part of the top-down discovery schema, if in case there are multiple patterns (all of them being active) targeting the same CI and has similar identification conditions set, one of them would be 'randomly' chosen. Because of this behaviour of the product, you may see a difference in outgoing connections or sometimes the entire map structure. The only way to streamline the pattern pick up by the discovery process is to evaluate and have one single pattern as active for one CI type. All the rest of the patterns should be inactive. OOB there would be one pattern actively targeting one CI class type and if there is a requirement to create more than the available pattern, then it has to be made sure that only of the patterns are active.
