UCMDB - NNMi Integration

In Discovery and Integration Content Guide,  we found below statement.

 

 

 

Can you please advise why we should not run UCMDB Layer 2 discovery jobs when NNMi integration is running? What will happen if we run both the adaptors?

Re: UCMDB - NNMi Integration

Hi!

 

You shouldn't run them in tandem because the NNMi server uses different (much better) logic to find Layer 2 Connections (i.e. via LDP, CDP, etc)... and so you will get excellent results from NNMi, but if you try running the same job in UCMDB, you may end up with duplicates.

 

At the end of the day, you should use the NNMi one rather than the internal UCMDB scripts.

Re: UCMDB - NNMi Integration

Keith,

 

If we only use NNMi Integration point in UCMDB to discover Network Devices, would that discover the relationships between CI's that are discovered by UCMDB discovery jobs vs NNMi SNMP Discovery?

 

For e.g. If there is physical top of the rack switch plugged into physical server in the Rack, would that relationship discovered in CMDB? In this case switch was discovered by NNMi and server by UCMDB.

 

Thanks

Sandeep

Re: UCMDB - NNMi Integration

The best use case I know of has to do with access point switches.  So,  you have a switch attached to a server that is an important server.  If you discover both the switch and the server in NNMi, it will merge the NNMi server with the UCMDB discovered server and connect your topolog this way.  You have to have the server Ci in both NNMi and UCMDB.

 

Make sense?

Re: UCMDB - NNMi Integration

Keith,

 

Yes that makes perfect sense. However, most of the customers use SiteScope or HPOM for server monitoring and NNMi for Network monitoring and practically they will not spend in licensing for Server monitoring in NNMi when they have other tools.

 

In this case if the server and both Network device are discovered in UCMDB, considering Cisco switch as most of the layer 2 topology jobs are for designed for catalyst, will it UCMDB discover that topology? Also when the same switch is imported from NNMi, reconciliation should merge the two CI's

 

Thanks

Sandeep;

 

I understand the licensing difficulties.  It might work with just UCMDB information... but the *preferred* method is the NNMi integration.  It discovers Layer2Connections based on many, many more protocols than UCMDB.

Re: UCMDB - NNMi Integration

Thanks Keith,

 

So take away is this, the best practice to map that kind of topology in CMDB is to


- Discover both server and switch in the NNMi

- Discover Server in UCMDB 

- Create Integration Point in CMDB for NNMi

- UCMDB will reconcile the Server CI and create CI for the Switch in CMDB (UUID)

- Switch is related CI to the Server and hence can be mapped in Studio with appropriate TQL

 

Cheers!

Sandeep;

 

Yep!  You have hit the nail on the head.  There are licensing implications of this approach, unfortunately.
