Optimate the use of your CMDB
CMDB can be described as the life nerve in any IT service organisation. With an updated CMDB you give your organisation the best tools to deliver an unequalled service and at the same time ensure optimal efficiency. A well-oiled CMDB will have a significant effect on all the service management processes in your organisation.
CMDB stands for Configuration Management Database and contains all relevant information about your IT environment.
The items, which are included in CMDB, are named Configuration Items or shortly CI's.
Configuration Items (CI's) typically consist if the following elements: Hardware, software, documentation, governance, and the services, which are delivered to the business. In addition, there is information of how the individual items, solutions, and services are interconnected. CMDB can in many cases also contain intelligence of who in the organisation that has the responsibility in relation to the systems in question.
To the right the elements in CMDB are showed in overall terms.
This article concerns CMDB in general terms and in particular CMDB in ServiceNow.
Construction of your CMDB in ServiceNow
In the mind of many a CMDB project is both long-running and comprehensive. Syspeople recommends an approach, where the project is split up into logical units, making it possible to finish subprojects as you go along. By that means it becomes manageable and iterative and you will continually see progress in the project. With the right angle of approach and project model, the project will become both achievable and clear.
Identify your business services
An excellent method for structuring and simultaneously give usability pride of place is to take your business services as a starting point. In that way the CMDB can be designed and reflect the services, your IT organisation delivers.
A business service is designed based on the service being delivered to a user - as an example mail or ERP - and is described from technologies and configuration items (CI's) as well as their connections.
Simple identification of errors via CMDB
A significant and often applied part of CMDB is the relations between the individual items. When the relations and all the system connections are documented in CMDB and linked with your monitoring, error diagnostics and troubleshooting become considerably easier.
Locate the error with vertical maps in CMDB
With access to directories of business services combined with monitoring, you will get the entire overview. When a user reports an error on, for instance, mail, it will often be immediately visible in the vertical overview of that business service. The overview will display any errors that may arise from your monitoring solution - in the case to the right, an error on a mailbox server.
Errors can be prioritised by "Impact" - to what degree the error has an impact on the organisation, since it will be visible which business services that are affected by the error. The priority will for that reason typically happen from, how essential the business service affected is.

Manual or automated update of CMDB
Many people choose to update CMDB manually. It can give a reasonably thumbnail sketch of the company's items and construction of network. But what happens, when changes are made? Is it possible to get all changes documented in the CMDB?
In practice, experience show that is very difficult to keep the CMDB updated manually.
CI's and relations continuously change in connection to maintenance and error recovery. It speaks for a more automated approach to the maintenance of CMDB.
There are also examples of CI's consisting of e.g. virtual machines and environments that change over time depending on strains.
Furthermore, the picture does not become less complex on the fact that a great deal of environments consists of both on-site, cloud, and hybrid solutions.
Automated update of CMDB
There are several options available for automated update of CMDB. With ServiceNow accompanies the application "Discovery", which self-acting examines the network and registers and updates both items and relations. Other solutions in connection to ServiceNow are also legitimate, including SCCM and VMware.
In any circumstances it can be advisable to proceed with caution, since network, where complete updates are made, can show itself to be unnecessarily complex.
