Where to set HEC httpinputq value ?

This is related to HEC queue size.

When I execute "index=_internal host=abc group="queue" name="httpinputq" | eval name=name+":"+host | stats values(name) by max_size_kb" => max_size_kb value showing as 107520KB.

Based on how indexing works diagram https://wiki.splunk.com/Community:HowIndexingWorks, HEC uses httpinputq but I am not able to find anything related to httpinpuq in Splunk Docs.

I am not sure from which configuration file max_size_kb value showing as 107520KB. I verified in all server.conf and inputs.conf files, but with no luck. Need help here to understand the source of max_size_kb value.

I also referred but with no luck: https://community.splunk.com/t5/All-Apps-and-Add-ons/When-HF-with-quot-Splunk-DB-Connect-quot-send-d...

To set httpinputq, below configuration is working in server.conf

Please change queue size as per your requirement.

[queue=httpInputQ]
maxSize = 10MB

server.conf and also as stated in your previous post, "queueSize" in inputs.conf also worked.

Thanks for your help and quick response on this.

Thank you for your quick response @harsmarvania57 

when I run above splunk query, existing max_size_kb value showing as 107520KB. But, I am not able to find from where this value is coming from. It's not there in any .conf files (Not in server.conf too).

Have you tried to check server.conf config using btool ?

@harsmarvania57 No luck with btool also. It's weird.

In that case, you have peristent queue configured. Check inputs.conf using btool for peristent queue.
