Does in-memory input queue configuration have any impact on response?</P> Tue, 16 Aug 2016 23:55:59 GMT https://community.splunk.com/t5/Getting-Data-In/Will-the-HTTP-Event-Collector-respond-with-any-error-if-it-can-t/m-p/230808#M44938 sandeep23 2016-08-16T23:55:59Z https://community.splunk.com/t5/Getting-Data-In/Will-the-HTTP-Event-Collector-respond-with-any-error-if-it-can-t/m-p/230809#M44939 <P>Yes - if we fail to enqueue events into the queues (in memory or persistent) we will give you back an error (and a 502 response code) to say the service is too busy to handle requests.</P> Wed, 17 Aug 2016 00:26:37 GMT https://community.splunk.com/t5/Getting-Data-In/Will-the-HTTP-Event-Collector-respond-with-any-error-if-it-can-t/m-p/230809#M44939 ineeman 2016-08-17T00:26:37Z https://community.splunk.com/t5/Getting-Data-In/Will-the-HTTP-Event-Collector-respond-with-any-error-if-it-can-t/m-p/230810#M44940 <P>@ineeman<BR /> How should we make sure that we don't hit this issue?
