uCMDB 10.01 + UD versus DDMi for network appliance asset data

Consider this:

DDMi currently collects detailed asset data about Network appliances ( the example I'll use is a fully loaded Cisco 6509 switch)

DDMI, through SNMP only, disocveres such things as the chassis, each fan module, each port module, each power module. It discovers at minimum a serial number and complete model description.

 

The same switch discovered in uCMDB 10 with SNMP consists of a single chassis with 144 ports, one chassis serial and that is it. No granularity, no individual modules modelled. This is fine for configuration management, but not for asset management.

 

So, if I move from DDMi to UD and lose my DDMi server, how am I going to get the amount of detail required into Asset Manager ?

When will the SNMP implementation in uCMDB 10.nn be augmented to discover the same amount of detail as DDMi does ?

 

As it stands, this is a show stopper for me migrating to UD. I would lose an enourmous amount of asset data in Asset Manager.

Re: uCMDB 10.01 + UD versus DDMi for network appliance asset data

Hello jowillia,

 

Due to the urgency issue that not all the attributes are being discovered by UCMDB UD, I would suggest to open a support case.

In addition to the contract data, please attach the following:

 

1) Provide also output of System Information
http://<ucmdb_server_name>:8080/jmx-console
UCMDB:service=ServerServices
viewSystemInformation

 

2) Communication log generated by the "Host connection by SNMP", The properties of the Discovered CI.

 

3) Exported properties of the DIscovered CI Cisco 6509

 

4) output of SNMPWALK sowing the attributes not discovered by the job.

 

Best Regards,

Juan Calderon

Re: uCMDB 10.01 + UD versus DDMi for network appliance asset data

Hi,

I have had a support case open for some time on this. The upshot is that there is a recognised gap between some aspects of DDMi server and UD replacement, and those gaps may be addressed in future releases of UD.

You are the first person I have spoken to, that recognises the sensible approach is to develop the uCMDB v 10 SNMP host resource scripts and the network device CIs and relationships,  to model a chassis based device as a bunch of related modules rather than a single device.

But, the walk for any specific switch will even differ from IOS version to IOS version. Walks of different types of switch will be even more different. 

Thus, fixing the current scripting is not a feasible approach. It may be possibe to fix it to recognise the specific 6509 I have used as an exampe, but there are at least 15 other device types in our network that have similar discrepancies between the DDMi detail and the DDMa detail.

I think that somone needs to take the DDMi SNMP scripting and modelling methods, and then turn them into a distinct uCMDB package.

 

But, having had that rant 😉 I will take your suggestion and open another specific case and see where it leads.

Thanks,

John

Re: uCMDB 10.01 + UD versus DDMi for network appliance asset data

Hi,

In my opinion, comparison of DDMi to SNMP related jobs isn't completely correct.

UD 10.01 using same to DDMi agents with exactly same capabilities.

I clearly understand that there are gaps, but it should not have such differencies.

Am I missing something?

Yes, the SNMP discovery of network devices is carried out by DDMi server, not the agents.

Converting the agents to UD then pointing them at uCMDB doesn't solve the problem. There are no agents on network devices..
