Cisco Firepower eStreamer eNcore Add-on for Splunk version 4 Install

Path Finder

I know this version is still in beta, I personally had a lot of issues getting it to install properly. In case it would help someone else, I wanted to provide some notes I wrote up.

You do not need to create a bookmark file. One reason you might want to would be to avoid ingesting old data.

# Where "" is the IP of your defense center


# Install the app through the UI and restart

# Missing steps:
# Edit the '/opt/splunk/etc/apps/TA-eStreamer/bin/' and '/opt/splunk/etc/apps/TA-eStreamer/bin/' adding the environment variable.
# For most, that will just be uncommenting out "#SPLUNK_HOME=/opt/splunk"

# Make sure your cert is located here: /opt/splunk/etc/apps/TA-eStreamer/bin/encore/client.pkcs12

# Instructions:
# TLS communication with the FMC, running the start up script, $SPLUNK_HOME/bin/bash test will detail those commands

# I had to change the commands a little bit to get them working in my environment:
/opt/splunk/bin/splunk cmd /opt/splunk/etc/apps/TA-eStreamer/bin/ test
# Please Enter the FMC IP:

/opt/splunk/bin/splunk cmd openssl pkcs12 -in /opt/splunk/etc/apps/TA-eStreamer/bin/encore/"client.pkcs12" -clcerts -nokeys -out "/opt/splunk/etc/apps/TA-eStreamer/bin/encore/"
#Enter Import Password:
#MAC verified OK

/opt/splunk/bin/splunk cmd openssl pkcs12 -in /opt/splunk/etc/apps/TA-eStreamer/bin/encore/"client.pkcs12" -nocerts -nodes -out "/opt/splunk/etc/apps/TA-eStreamer/bin/encore/"
# Enter Import Password:
# MAC verified OK

Create and update your local folder:

# app.conf

# encore.conf
client_enabled = 0
port = 8302
write_packets = 1
host =

# inputs.conf
# Where data is written to
index = org_ids

# The current status

# Maintain cleanliness every 15 mins - this should never have any output
[script://./bin/ clean]
disabled = 0

# The main data source

disabled = 0

# props.conf
# Sourcetype
TIME_PREFIX = \sevent_sec=
# the original 'TIME_PREFIX = event_sec' was being damaged by the 'orig_event_sec' field
# TIME_FORMAT = %s was commented out in the default

# NOTE: (Optional)the following transforms replaces the "source" field with the "rec_type_desc" 
# value. I find this to be helpful as it creates an efficient way to search your events after indexing
TRANSFORMS-extract_rec_type = estreamer_replace_source

# transforms.conf
DEST_KEY = MetaData:Source
REGEX = \srec_type_desc\=\"([^\"\=]+)"

# /opt/splunk/bin/splunk cmd /opt/splunk/etc/apps/TA-eStreamer/bin/ stop

If you run into additional issues here, I would suggest enabling/disabling the app and the scripted inputs through the UI.

Also, this app requires the pid and bookmark files in "/opt/splunk/etc/apps/TA-eStreamer/bin/encore"

Hey joe, last line of your post about the bookmarks. Did you have to create that bookmark file manually? I get a "Bookmark file <path> not found" error in my estreamer logs.
