CMDB, integrations and reporting

Knowing what IT you have, connecting systems and measuring work.

📖 Key ideas

The CMDB (configuration management database) records IT items: servers, apps, laptops and how they connect.
Configuration items (CIs) link to incidents and changes to show impact.
REST APIs (Table API, Scripted REST) let other systems read and write records.
Reports and dashboards show counts, trends and SLA performance.
Clean CMDB data makes impact analysis and automation reliable.

💡 Real-life example: Like a family tree for a company's IT: if one server falls ill, you can see which apps and teams it affects.
