Discovery: Virtual Servers vs Virtual Machine Instance

[kmlutz]

Hello All,

We have recently rolled out Discovery to our production environment.   We are starting with our main data centers and mostly targeting infrastructure items such as servers.

We are comparing the results from Discovery to our homegrown CMDB.

One thing we have noticed relates to "virtual" servers and vCenter.

In our homegrown system, the team has entries listed as virtual servers but when Discovery collects the data on these entries - they are listed only as a Virtual Machine Instance and have no record in the virtual server class.

I have reviewed the WIKI and it seems like it may have to do with how these servers are created within vCenter...possibly because a template is used to "build" this entries.

Can someone provide a specific distinction between a virtual server and virtual machine instance and how Discovery makes that distinction?

Thanks.

HI Doug,

A quick question>

Is it possible that Servers which were discovered first and then their vmware instances were discovered, may not be able to create relationship? I have deleted few of the servers and then rediscovered, the relatioship established when rediscovered.

Absolutely possible since you proved it, but not the way I have always understood it to work.  "Shouldn't" matter what side gets discovered first.
