Release notes for the Splunk Common Information Model Add-on

Version 4.9.0 of the Splunk Common Information Model Add-on was released on September 22, 2017.

New features

Version 4.9.0 of the Splunk Common Information Model Add-on includes the following new features.

Setup page improvements

  • Improved user experience for adding index constraints to data models.
  • Choose whether to run acceleration searches until the maximum time is reached or not. This option can improve performance for some deployments.

See Set up the Splunk Common Information Model Add-on.

Common action model improvements

  • You can now use the ModularActionTimer class in the cim_actions.py library to report duration for your action. Update modular action scripts to use this script to continue to report duration for your actions. Modular action data is no longer retrieved from the _internal index and added to the Splunk Audit Logs data model. For an example script using the new class, see Example response action in the Splunk developer portal.
  • Improved support for complex ad-hoc actions.

Data model improvements

  • The Splunk Audit Logs model now includes a component field to specify which part of a modular action script is involved in the event. For example, to specify the portion of the script that populates the duration field.
  • Updated descriptions for the user and src_user fields in the Change Analysis data model for clarity. See Change Analysis.
  • The Splunk_Audit.Search_Activity dataset is now a BaseEvent dataset instead of a BaseSearch dataset. As a result, you can use that dataset in a search with tstats. Update searches with this dataset to account for the new format. For example, you can use the dataset in search:

| tstats count from datamodel=Splunk_Audit.Search_Activity where (Search_Activity.info="granted" OR (Search_Activity.info="completed" Search_Activity.search_type="subsearch")) by Search_Activity.search_type

| tstats `summariesonly` first(Search_Activity.search) as search,first(Search_Activity.total_run_time) as run_time,first(Search_Activity.user) as user from datamodel=Splunk_Audit.Search_Activity by Search_Activity.search_id | stats min(run_time),avg(run_time),max(run_time),values(user) as user,count by search | eval "min(run_time)"=round('min(run_time)', 1),"avg(run_time)"=round('avg(run_time)', 1),"max(run_time)"=round('max(run_time)', 1) | sort 500 - "avg(run_time)"

Upgrade requirements

Splunk platform version Upgrade activity
6.6.X or later If you apply custom tags to data mapped to CIM data models and you use these tags in searches and search filters, add these tags to the whitelists for those models. See Set up the Splunk Common Information Model Add-on for details about the tags whitelist field.
6.5.X or earlier No upgrade activity required.

Compatibility

Version 4.9.0 of the Splunk Common Information Model Add-on requires Splunk platform version 6.4.x or later. Some functions on the CIM setup page, such as the accelerate until max time setting, are only available in version 6.6.x and later.

Known issues

This version of the Splunk Common Information Model Add-on has the following reported known issues.

Date filed Issue number Description
2018-12-05 CIM-784 Common Action Model calculates info_file incorrectly when using per-result alerting
2018-01-10 CIM-616 CIM 4.8+ causes "guided search" build_id errors in Enterprise Security.

Workaround:
Upgrade to Enterprise Security 4.7.x or higher
2017-11-01 CIM-584, CIM-601 Setup View (cim_setup) does not work on 6.4.x.

Workaround:
Use Splunk Enterprise 6.5.x or higher.

Use Splunk Enterprise Settings to update data models and macros.

2017-10-31 CIM-583 Network Resolution data model has multiple references to reply_code_id field
2017-09-27 CIM-575 CIM Standalone: Setup page is broken

Workaround:
Expose macros in web.conf.
  1. Create a local web.conf file: $SPLUNK_HOME/etc/apps/Splunk_SA_CIM/local/web.conf"
  2. Place the following lines in the file:
[expose:admin_macros]
pattern = admin/macros

[expose:admin_macros_ELEMENT]
pattern = admin/macros/*
methods = GET,POST


2017-09-14 CIM-571, CIM-577 Python logging is not user-timezone agnostic.
2016-10-05 CIM-433 btool error: Invalid key in stanza lookup:cam_category_lookup in Splunk_SA_CIM.

Workaround:
Edit SA-Utils/README/managed_configurations.conf.spec to include this entry at the very end (under the lookups stanza): 
expose = [0|1]
   * Whether to expose the contents of file backed lookups
   * Exposes contents via eai:data
   * Optional.
2016-09-16 CIM-428, SPL-128919 sendalert reflects owner="system" for adhoc action invocations
2016-07-08 CIM-383 Setup screen shows "I am legend" or "Unable to render setup" on 6.4.x

Workaround:
Delete the setup.xml file (usually left over from a previous version) from the Splunk_SA_CIM/default folder and browse to the "cim_setup" view directly.
2014-07-07 CIM-169 Remote search log warning messages from acceleration due to long search strings

Workaround:
Turn off truncation on indexers in etc/system/local/props.conf as shown:

[splunkd_remote_searches]
TRUNCATE = 0
