The CMDB Graph


GraphicalInterface_After2016Versions

Note: This graphical user interface is specific to Product name - ev itsm.png versions later than 2016.

Open url.png See version 2016 and earlier.

Definition

The CMDB Graph enables you to view relationships between configuration items, i.e. impacting CIs and impacted CIs, and browse through these interactions.

EndDefinition

You can save an image of the graph at any time. This image is called a baseline.

  • This snapshot represents an infrastructure or service at a given time in a specific context.
  • It provides a reference version when managing change or deploying a release. It facilitates rollback to an initial version in the event of unexpected issues.
     

Definitions

  • A CI is an impacting CI when its unavailability leads to the unavailability of another CI.
  • A CI is an impacted CI when its unavailability is due to the unavailability of another CI.
     

Benefits of the CMDB graph for the IT Department

  • Provide a quick view of the CIs impacted by incidents, service requests and change requests.
  • Understand how the failure or unavailability of a CI affects other CIs. In case of unavailability of one or more items, all the unavailability chain will be displayed in red.

    Example documentation icon EN.png You see that an application is no longer accessible because it is installed on an unavailable server.

  • Analyze the impact of an infrastructure modification on the production of services, or the impact of a software version upgrade prior to wide-scale deployment.

    Example documentation icon EN.png  You can identify all CIs affected by the installation of a patch on a server.

  • Provide a quick view of CIs whose capacity threshold is exceeded.

Examples

Impact of the unavailability of the Oracle Server CI on other CIs

  • Unavailability of the Database Server CI 
  • By extension, unavailability of the Payroll Application and Expense Account Application CIs
     

Capacity threshold of the Database Server CI exceeded

  • CPU Usage capacity is associated with the CI, with optimum usage thresholds between 10% and 50%.
  • An exceeded threshold alert appears in the graph once CPU usage exceeds 50%.

Notes

  • Values are displayed in real-time, e.g. number of incidents/requests for the current CI, state of unavailability, exceeded capacity threshold.
  • You should specify if the relationship is blocking or non-blocking in the Impacting CIs and Impacted CIs tabs of each CI form.
  • You can move a CI in the graph without affecting its relationship with the other CIs.

Best Practice big icon.pngBest practice

  • If you want to compare a current graph with a previous graph, you should save the image in a baseline.
  • If you only want to store a snapshot of the display without creating a baseline, you can save it as an image.
  • You should start with the display of an existing baseline when organizing your graph.

Characteristics specific to versions 2016 and earlier

The CMDB graph in versions 2016 and earlier is different:

You can also view baselines by selecting Extended CMDB > Administration > Baseline in the menu.
