Learning CMDB

[its_SumitNow]

Hi everyone,

I’m planning to start learning CMDB and ITOM. Could you please suggest a structured learning path or key topics I should focus on to gain solid insights into CMDB?

Hi @its_SumitNow ,

ITOM consist of several different products, but in general, I would recommend to follow the ServiceNow University training modules for CIS Discovery, CIS Service Mapping, CIS Event Management and CIS Data foundation... just as examples.

Hi @its_SumitNow 

Even I have interest to learn ITOM and have been going through playlist of various itom specialist YouTube channels. Most of them follow same flow and here are topics which I understand needs be learnt for ITOM.

Here is what I gathered and hope to learn in coming days:

1) Introduction to Cmdb. Showcase CI classes, CI health and compliance dashboards, CI relation and dependency to each other

2) about Mid server, How to install and configure it. And control using PDI

3) About discovery, how to configure it and classic example of window system discovery 

4) Further delve into topics and types of discovery like top and bottom approach

5) teach about 4 stages of discovery like identification, reconciliation,probes, sensors etc

6) Event mapping and how alerts are mapped in system and how to create incident using alerts.

7) About monitoring tools available market and some showcase integration with solar wind. And how to debug and identify issue using Ecc queues etc

Thanks and Regards,

Mohammed Zakir

• Learn CMDB basics: what CMDB is, what CIs are, CI classes, attributes, and lifecycle

• Understand CI relationships and how servers, applications, and services are connected

• Learn how CMDB data is populated: Discovery, Service Mapping, integrations, and imports

• Study Discovery (ITOM): MID Server, credentials, patterns, schedules, and troubleshooting

• Learn Service Mapping to build Application Services and dependencies

• Understand CMDB Health: completeness, correctness, compliance, and governance

• Learn Event Management: events, alerts, correlation, and impact using CMDB

• Practice real use cases: change impact analysis, incident impact, and root cause analysis

• Do hands-on practice in a PDI: run discovery, create relationships, and check CMDB health

Hi @its_SumitNow I would recommend below sequence.

1. Knowing CMDB concepts are important for ITOM. For CMDB, you can go through "Configuration Management Database (CMDB) Fundamentals On Demand" course in Now Learning which covers the details of three main components of CMDB. "Data Ingestion, Governance and Insights" including the technical components used in ServiceNow for each functionality.

2. ITOM has 3 parts: Visibility, Health and Optimize.

Visibility has two applications mainly: Discovery and Service Mapping. Again, the now learning courses are available for each application with simulation labs.

Health: Event Management, Health Log analytics and Agent Client collector. Understanding the overall functionality and features of Event Mgmt itself will take lot of time. So, take time to learn and practice before stepping on to HLA, ACC and Cloud Provisioning applications (Optimize).

All the best for your learning!
