Install the Splunk Common Information Model Add-on

1. Download the Common Information Model add-on from Splunkbase at https://apps.splunk.com/app/1621/.
2. Review the indexes defined in CIM.

   1. The previously deprecated cim_summary index definition is now removed. If you have a custom configuration for this in your local indexes.conf file, it will persist as-defined.

      1. If you are no longer using this index definition, remove the stanza from your local indexes.conf file before installation.
      2. If you are still using it, you will need to revise the stanza if you were previously relying on parts of the deprecated default cim_summary index definition.
   2. The cim_modactions index definition is used with the common action model alerts and auditing. Make sure that the index exists and assign the appropriate Roles to search the index.

3. Install the Splunk Common Information Model Add-on to your search heads only.
