Discovery[Asset/device mapping to IP address]

[sushantm]

HI Everyone,

I have   some queries on discovery module. How MID server will update the CMDB about software or any other information of a device in IP range to service now instance.

As I read MID server will get the info from devices and update into service now database..

But not able to figure out,

1. In CMDB there will be asset(hardware) info   and MID server will push data based on IP address of the device.

2. Are we storing IP address of each asset in the table?

3. if not , How it is mapping the both?

Thank you

Hi Sushant,

Discovery is not a small module that we can explain in one thread. To begin you can start from here.

Hi Vivek,

Thank you for reply.

I have gone through documents, I understood the part where MID server will get the info from devices.But while updating it in CMDB, There should be some mapping ( may be device name-ip address) or something?

If you explain this part it will be more helpfull.

Thank You

Hi Sushant,

ServiceNow Discovery will discover the Hardware through four different phases.

- Shazzam phase- it will identify the end CI's open ports to give a way for classification

- Classification phase - Based on the open ports Classification phase will identify the device class based on operating system, etc.

- Identification phase - Identification will determine ServiceNow has to create a new record or update the existing record. There is set of hardware rules which will determine the unique fields like a Serial number, name, etc for each class in CMDB.

- Exploration phase - In this phase, it will identify more information about device like software, storage, applications.

This may answer your question i guess.

Vivek
