Hey, # rpm -q rsyslog rsyslog-elasticsearch rsyslog-8.24.0-16.el7_5.4.x86_64 rsyslog-elasticsearch-8.24.0-16.el7_5.4.x86_64 Rsyslog in RHEL 7.5 is not able to push data into Elastic 6.x due to breaking API change - https://www.elastic.co/blog/strict-content-type-checking-for-elasticsearch-rest-requests It used to be opt-out, now in 6.x series this can't be configured anymore: # curl -i -H "Content-Type: xxx" -XGET 'http://localhost:9200/' -d '{}\n' HTTP/1.1 200 OK Warning: 299 Elasticsearch-5.4.3-eed30a8 "Content type detection for rest requests is deprecated. Specify the content type using the [Content-Type] header." "Wed, 26 Jul 2017 14:33:28 GMT" Now in 6.x: # curl -i -H "Content-Type: xxx" -XGET 'http://localhost:9200/' -d '{}\n' HTTP/1.1 406 Not Acceptable content-type: application/json; charset=UTF-8 content-length: 74 {"error":"Content-Type header [xxx] is not supported","status":406} Upstream does seem to send the header correctly, I request backport of this into RHEL7 please. https://github.com/rsyslog/rsyslog/commit/462be8b2ee4747a5317930d11018ce5ccb3726e0 https://github.com/rsyslog/rsyslog/commit/50d8e5cb391d8e0b984c725066a688da8b723b61 Thanks!

I think we already have ticket for it here: https://github.com/openshift/origin-aggregated-logging/issues/625 This will be implemented once we upgrade to ES 6.x I would not expect us to implement it before we finish upgrade to ES 5.x

Is there any update on this? It's effecting my ES 6 infrastructure. I'd be happy to help in any way that I can.
This issue was not selected to be included either in Red Hat Enterprise Linux 7.7 because it is seen either as low or moderate impact to a small amount of use-cases. The next release will be in Maintenance Support 1 Phase, which means that qualified Critical and Important Security errata advisories (RHSAs) and Urgent Priority Bug Fix errata advisories (RHBAs) may be released as they become available. We will now close this issue, but if you believe that it qualifies for the Maintenance Support 1 Phase, please re-open; otherwise we recommend moving the request to Red Hat Enterprise Linux 8 if applicable.
