HTTP event collector client AJAX error "readyState 0, status 0, statusText error"

cafissimo — Mon, 05 Mar 2018 15:12:05 GMT

Hello,
while trying to send messages to Splunk HTTP event collector through javascript inside a web page, I sometimes get this erro:

readyState 0, status 0, statusText error

It seems, but I am not sure, that this error is related to the volume of HTTP POSTS that are concurrently made.
Is there any kind of limit to HTTP POSTS that a single HEC is able to handle at a time?
If yes, what is this limit? I cannot find a sizing guide for HECV, other than what is suggested in this page " http://dev.splunk.com/view/event-collector/SP-CAAAE73 ", but there are no clues about volumes.

Thanks in advance.

Are you getting this error after executing an AJAX request from a click or keystroke action?
If so, are you doing a return false or e.preventDefault(); (Where e is your event).

function onClick(sender, e) {
  e.preventDefault();
  $.ajax({
    type: 'POST',
    url: 'http://yoursplunk.com:8088'
  });
}

You can override this automatic configuration by making changes to server.conf. Increasing the number of threads can increase the amount of memory that the Splunk Enterprise instance uses.

In the $SPLUNK_HOME\etc\system\local, create or edit server.conf.
In the [httpServer] stanza, set the maxThreads attribute to specify the number of threads for REST HTTP operations that Splunk Enterprise should use.
Set the maxSockets attribute to specify the number of sockets that should be available for REST HTTP operations.
Save the file.
Restart Splunk Enterprise. The changes should take effect immediately

Please find the default value
maxThreads=100000
maxSockets=50000

Hi logloganathan

This is an exact copy of the Splunk Documentation: https://docs.splunk.com/Documentation/Splunk/7.0.2/Troubleshooting/HTTPthreadlimitissues
You cannot copy answers from Splunk Documentation and post them as your own, that is plagiarism.

Well you should add your source to the copied section, then it would not be a problem.
This has to do with the respect of the original writer...
