eStreamer eNcore for Splunk is a plugin based eStreamer client built from scratch in Python designed to deliver fully qualified event data to Splunk from Firepower 6.x platforms. If you have experienced problems getting the Cisco eStreamer for Splunk app version 2.2.1 and 2.2.2 working with Firepower 6.x you should move to this new application so that you can leverage the many improvements listed below.
eStreamer eNcore for Splunk is a Technical Add-on designed purely to collect data and be installed on a forwarder.
New in this solution:

Version 3.5.6 Updates
*Removed default disabling of the cisco:estreamer:data source type
*Removed duplicate aliasing for action/blocked fields
- Fixed encore settings which did now allow for control the writing of metadata

eNcore v3.5.3 resolves issues with previous v3.5.x versions where eNcore would crash under certain conditions.
All eNcore v3.5.x versions provide significant performance enhancements over pre-v3.5 versions.
eNcore version 3.5.0 features performance improvements – the ability to process a significantly higher event rate. This improvement requires no additional configuration on the part of the user.
However, if the eNcore platform has four or more cores, then additional performance improvement can be gained by adjusting a parameter in the configuration file, estreamer.conf. This parameter is called “workerProcesses” and is highlighted below:
--- rest of config file omitted ---
The highlighted line shows the “workerProcesses” to be set at 4. It can be set anywhere from 4-12, but with four or more cores, testing showed the best performance when set to 12.
See Details section for more Release Notes on Version 3.5.0
