ServiceNow Integration with SCCM

[sayub]

Hi,

I have a client requirement to integrate SCCM with Service and i think i understand the steps of integration but i wanted to understand a few things from the conceptual perspective.

We are discovering assets in their environment such has (Hardware: windows, UNIX devices, SNMP enabled devices, Storage etc). E.g. in case of windows devices e..g we are finding all out of box information that discovery finds such as information regarding the node, model, manufacture, IP, Domain, RAM, version also running process and applications running on that Node, Disk and network adapters, memory and TCP connections. All this information is retrieved from out if box discovery.

I am not a SCCM expert but based on my research SCCM managing large groups of computers running both Windows and Unix which are discovered as part of our discovery,; and it find information regarding

• Operating System: ram, os_version, os_service_pack
• Processor: cpu_core_thread, cpu_speed, os_address_width, cpu_manufacturer, cpu_core_count, cpu_name, cpu_type, cpu_count
• Disk: disk_type, short_description, manufacturer, device_id, last_discovered, name, computer, disk_space
• Network: dhcp_enabled, mac_address, name, cmdb_ci, netmask, last_discovered, ip_address, default_gateway
• Software: Software packages installed

Now i am curious to understand a couple of thing:

• Why would we need SNMP integration when our out of box discovery is finding the information; or is that a question for the client to specify what information is not found by out of box discovery and can be imported from SCCM (if available)?
• Lets assume we ran discovery on a IP target and created a CI for that node in the CMDB, but out of box discovery didnt provide a specific set of information which is getting captured in SCCM database, now once i import the same IP node data from SCCM (post SN to SCCM integration); will my CI record be update or there will be a new record created in CMDB with extra information from SCCM for the same IP?
• Does it store info for SNMP enabled devices also?
• What i am trying to understand is what new metrics/data does SCCM integration provides that out of box discovery doesn't and how to make sure that existing IP that were found using discovery are updated when SCCM data is imported rather than creating duplicates and mess up the integrity of the CMDB.

Thanks

On the go so a placeholder response till I get more time.  

We have sccm and serveral other integrations and last I checked sccm uses transform and import tables. This means I don't think it uses the same datasource precedence rules I might use for keeping other integrations from overwriting each other fields.  

While we pull in many fields with SCCM we primarily use it for last logged in, last hw scan date, and IP/network adapters.  

Cannot speak to the SNMP question as that doesn't get usd within our sccm integration st all.

Thanks Malone and i will wait for your detailed response, but it seems from your response that since SCCM might provide some extra information for a IP thats already been discovered but it might not follow the same datasource precedence rules and not merely just add extra info to the discovered IP node BUT instead either create a new record for the same IP with information from SCCM or require normalization of some sort after the data is imported.

Is that a valid understanding?

Found a great article on Service Now Docs and it answers my question

Collect software data with either SCCM or Discovery
