Configuration Management (CMDB)

The configuration management module defines the objects to be managed inside iTop. It defines all the physical devices (PCs, Servers, Printers, Network devices, Telephones, etc.) but also some logicals elements (Groups, Application Solutions, Business Processes), software objects (Software Instances, Licenses, etc.) and structuring entities (Organizations and Locations). Persons and Teams are also defined in this module.

In order to keep the elements to manage as simple as possible while covering most IT needs, the configuration management domain has been split into 5 modules:

Module Name Required Description
Configuration Management Core mandatory It includes all the basic building blocks of the CMDB: Organizations, Persons, Teams, Servers, Software Entitites, Groups…
End-Users Devices optional This module adds end-user related devices: PCs, Telephones, Printers and other Peripherals.
Virtualization Management optional This module adds Virtual Machines, Hypervisors, Farms
Advanced Storage Management optional This module adds storage objects: SAN, NAS, Storage Systems, Fiber Channel Interfaces, Volumes…
Data Center Management optional This module adds objects to manage a datacenter: racks, enclosures, power connections…

Service Management

At the heart of the ITIL methodology, service management is a key part of iTop. The relations between the organizations are defined by the customer and provider contracts defined in this module. The delivery model used by the ticketing is also defined in this module. In iTop 2.0, service management comes in to alternative flavors:

Service Management for Enterprises This module is best suited to describe an single company environment where the same shared infrastructure is used to deliver IT services to all the organizations.
Service Management for Providers This module aimed at describing a service provider environment in which a dedicated infrastructure is operated for each customer.

The documentation for these two modules is grouped in: Service Management (services, SLAs, contracts) Module.

Ticketing

When installing iTop, two different types of ticketing are available:

Simple Ticketing This module provides a simple ticketing scheme for processing all user requests and incidents using a unified ticketing with a simple workflow.
ITIL Compliant Tickets This module follows the ITIL guidelines by distinguishing User Requests tickets from Incident tickets

Change Management

Two different types of Change Management tickets are available in iTop:

Simple Change Management Use this module to track all your changes using one type of “Change” ticket with a simple process.
ITIL Compliant Change Management Use this module to track all your changes using ITIL compliant processes, with Normal / Routine or Emergency changes, each with a different life-cycle.

Problem Management

Obsolescence and Archiving

Introduced since iTop 2.4, the standard Data Model includes an obsolescence and an archived notions defined per class of object.

  • Obsolescence: On user preference, obsolete objects can be hidden from lists displayed in the console.
  • Archiving an object is equivalent to a 'soft delete'
