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-data-to-Indexer/td-p/418246 ... View more
