Most vendor management packs are sealed so that you cannot change any of the original settings in the management pack file. However, you can create customizations, such as overrides or new monitoring objects, and save them to a different management pack. By default, Operations Manager 2007 saves all customizations to the Default Management Pack. As a best practice, you should create a separate management pack for each sealed management pack you want to customize.
Creating a new management pack for storing overrides has the following advantages:
- It simplifies the process of exporting
customizations that were created in your test and pre-production
environments to your production environment. For example, instead
of exporting the Default Management Pack that contains
customizations from multiple management packs, you can export just
the management pack that contains customizations of a single
management pack.
- You can delete the original management pack
without first deleting the Default Management Pack. A management
pack that contains customizations is dependent on the original
management pack. This dependency requires you to delete the
management pack with customizations before you can delete the
original management pack. If all of your customizations are saved
to the Default Management Pack, you must delete the Default
Management Pack before you can delete an original management
pack.
- It is easier to track and update
customizations to individual management packs.
