Obsolescence

Introduced by iTop 2.4, the Data Model now includes an obsolescence notion defined per class of object, to improve user experience by highlighting / hiding obsolete objects.

Purpose

Highlight obsolete objects

Object defined as obsolete are flagged in the console to make this aspect obvious, by graphical icon and tag.

On a list:

On an object:

On a list of linked object:

Improved Impact Analysis

Obsolete objects are ignored by Impact Analysis

Before iTop 2.4.0:

After:

Hide obsolete objects

Based on user preference, objects which are defined as obsolete, are removed from displayed lists in the iTop console.

An obsolete object details is displayed regardless of user preference.

The same Farm as above displayed for a user, requesting to not display obsolete objects:

Be cautious with this user preference, it does hide existing objects:

modify mode

  • In details screen, on a drop-down list: obsolete objects will not be proposed.
  • In a relation tab, obsolete objects will not be displayed, so cannot be removed.
  • In a relation tab, obsolete objects cannot be added.

other display difference

  • Shortcut display a list without obsolete objects
  • Dashlets do not include obsolete objects
  • Global Search do not return obsolete objects
  • Audit does not report audit errors on obsolete objects
  • RunQuery does not return obsolete objects
  • Export should return a list without obsolete objects
CSV import of obsolete objects is still possible in this mode

Searching for obsolete objects

Use RunQuery and automatic attribute obsolescence_flag

Be cautious to set User Preference show obsolete data before running the query, otherwise the query won't return anything!

Limitations

obsolescence_date won't be documented unless the iTop cron is running.
This is done in background as an asynchronous task
User Portal never takes into account the user preferences, so obsolete data are visible unless filtered by portal scopes

Default obsolescence rules

Which objects are Obsolete?

In general:

  1. Objects with a status equal to obsolete or inactive
  2. Objects being a sub-object of another one, are obsolete if their main object is. Example: Physical Interface is obsolete if its ConnectableCI is. There are two exceptions to this rule: a Virtual Machine and an Hypervisor are obsolete if and only if their own status is obsolete
  3. License expired more than 15 months ago, (Search query cannot be cached, so cautious with high volumes)
If you want to notify obsolete contacts, be aware that this will fail if the user chose to hide obsolete objects in his preference
