It is based on the Class Manager > Dependent Relationships setting. There can be hosting or containment rules.

Let's take the hosting rules for example. We have a Win Server running a Tomcat application. IF we wanted to uniquely identify the Tomcat, based on e.g. the config file path, this will still not be good enough, as Tomcat can be installe don multiple machines, with same path everywhere. So the identification engine would not know which one to update.

By using dependent relationships (as most applications use), we force the identification to first identify the Win server host on which our Tomcat process is running, and only then identify the Tomcat app in the context of the host.

Hi,

Thanks for your reply.

I am new to this CMDB dependency rules.

I checked Out of the box class "Tomcat" and i can see below attached screen.

consider if i am importing tomcat records via Import set and how (based on which attribute)  it will identify the host(consider relationship - tomcat Runs on Win server).

do we need to add any identification rules to Win server table or adding dependent relationship will take care of the identification. please help here to understand the concept.

and where we can track the logs for Identification and recon rules execution logs after the import set run
