Configure 10Gbps network capture - Invalid key in stanza [streamfwd] in /opt/splunk/etc/apps/Splunk_TA_stream/local/streamfwd.conf,

Hey Splunkers,

Why am I getting the following error message when running dedicated capture mode for Splunk stream? Followed the instructions outlined here.

I'm currently testing dedicated capture mode on Ubuntu instead of RHEL/CentOS. I don't think thats the problem though.

Invalid key in stanza [streamfwd] in /opt/splunk/etc/apps/Splunk_TA_stream/local/streamfwd.conf, line 4: dedicatedCaptureMode (value: 1).
Did you mean 'duplicatePacketWindow'?

Here are my current config files for directory /opt/splunk/etc/apps/Splunk_TA_stream/local#

inputs.conf
[streamfwd://streamfwd]
splunk_stream_app_location = http://localhost:8000/en-us/custom/splunk_app_stream/
stream_forwarder_id =
disabled = 0

streamfwd.conf
[streamfwd]
dedicatedCaptureMode = 1
streamfwdcapture.0.interface = 0000:86:00.1

streamfwd.xml.bak

<InterfaceRegex>enp134s0f1</InterfaceRegex>

Re: Configure 10Gbps network capture - Invalid key in stanza [streamfwd] in /opt/splunk/etc/apps/Splunk_TA_stream/local

Was this ever answered somewhere? I'm having the same issue now using Stream 8.0.2 and Splunk 8.2.5

@chrisjk , @joerosen2020 - That option (dedicatedCaptureMode) is not available in streamfwd.conf.spec file.

But I do see that option in the latest Add-on documentation (https://docs.splunk.com/Documentation/StreamApp/8.0.1/DeployStreamApp/ForwarderParameters). So it seems like it's an issue from the Add-on side.

I hope this helps!! Upvote/karma would be appreciated!!
